calling an element and multiplying from a double list

am saying that if Wait is found it writes in the csv file the line that was written in the previous step as it is.. if the previous step was presskey. then it writes the line of presskey and if it is touchscreen it writes the line of touchscreen.. but i don't know how to get the previous line and write it again. u know what i mean. Its not list ... when it finds wait .. it writes the previous line as it is

So this is the if condition but,, how to read the previous line of the csv file..
I maean if it found Wait. It just reads the previous line and repeat it and put in the pause column the value inside MenuInfoList[i].-.. Putting the value is not a problem..

but the problem if there were two waits after each other..

if (MenuActionList[i].Contains("Wait")){
                     * if(!MenuInfoList[i]=0) continue;
                     * int pause=MenuInfoList[i];

// reading the previous line and repeat it

I can then put the pause inside the csvgenerate method

I don't think you'll need countSize now as you can get the size of the buffer from the Count property of the Lists which should be the same for all three.

This is broadly what I think the generatecsv method should look like now (you don't need the two other 'helper' methods):

The Menu_Tree method won't work as it stands since you need to return all 3 lists, not just XX. You'll therefore need to use out parameters for this:

Addline in csv Method

static void addlinecsv(int MobileID) {
            List La = Menu_Tree(MobileID);
            List Br = Menu_Tree(MobileID);
            List zz = Menu_Tree(MobileID);
            //  double La=0;
           // double Br=0;
           // double zz=0;
            int a = 4;
            string[] buffer = new string[a];
            string ProgramPfad = (@"C:\Robotron\MobileRobotDaten\" + MobileID + ".csv");
            Menu_Tree(MobileID);
           for (int i = 0; i < a;i++ )
           {
               buffer[i] = (MobileID + ";" + 3 + ";" + 1 + ";" + La + ";" + Br + ";" + zz + ";" + 71 + ";" + -51 + ";" + 30 + ";" + 400 + '\n');
               File.AppendAllText(ProgramPfad, buffer[i] + "\r\n");
           }
        }

I don't see why it should be a problem.

The List variables (X, Y and Z say) will be passed in as out parameters. So all you need to do at the top of the Menu_Tree method is to instantiate them:

X = new List();
Y = new List();
Z = new List();

As Lange, Breite and z will no longer be out parameters, you'll need to define them within the method itself:

double Lange = Breite = z = 0;

Now, each time you generate a new set of Lange, Breite and z values, just add them to the appropriate Lists:

X.Add(Lange);
Y.Add(Breite);
Z.Add(z);

There shouldn't be anything else to do and the presence of the Lists won't interfere with the rest of the existing code.

This implys that i should change every Lange and Breite and z in the Menu_Tree Method into double List which will make many errors when multipying Math.Abs(L[0]) * X / 100; and when List X = Convert.ToDouble(words[0]); List Y = Convert.ToDouble(words[1]); how can this be solved

If you want to print multiple lines to the file, then your Menu_Tree method has to return Lists of values rather than just a single set of values.

There's no way around that because, as things stand, the method will always return the same set of values.

Once you have the Lists you should be able to write the whole lot to the file from within a single method using a loop. The fixed lines can be written individually before and after the loop.

This is what i did in the second method that adds line into the csv line

what it does is that: it writes the x,y,z of the first presskey it finds and also in one line... It does not begin a new line each time

So, what am trying to do is to make a new line after the value 400 and add the vaalues line by line of the MenuAction according to if its Touchscreen or PressKey and not the first value only and repeating it.. like it does now

 // Add Line to csv
        static void addlinecsv(int MobileID) {
           
            double La=0;
            double Br=0;
            double zz=0;
            int a = Menu_Tree(MobileID, out La, out Br, out zz);
            string[] buffer = new string[a];
            string ProgramPfad = (@"C:\Robotron\MobileRobotDaten\" + MobileID + ".csv");
            Menu_Tree(MobileID, out La, out Br, out zz);
           for (int i = 0; i < a;i++ )
           {
               buffer[i] = (MobileID + ";" + 3 + ";" + 1 + ";" + La + ";" + Br + ";" + zz + ";" + 71 + ";" + -51 + ";" + 30 + ";" + 400);
            File.AppendAllText(ProgramPfad, buffer[i]);
           }
        }

I am returning x,y,z depending on if its touchscreen or presskey....

Well, it's only returning one set of values because the 'out' parameters for the Menu_Tree method (namely: La, Br and zz) are all 'scalar' doubles.

I thought at one time you were returning Lists of doubles?

The thing is ... in the buffer[2]... The coordinates of the steps should be written.. For example

for MobileID 1002

Coordinates of Q in the first press key
Then Coordinates of O in pressKey
Then TS:Coord
Then T in pressKey

so x,yz of each one of those should be written line after line

So what i did is the following..

I made 3 methods the first one is adding the first 2 fixed lines.. The values of these lines are fixed

 static void generatecsv(int MobileID)
        {
            string ProgramPfad = (@"C:\Robotron\MobileRobotDaten\" + MobileID + ".csv");
            double La=0;
            double Br=0;
            double zz=0;
           // double Lange = 0;
          //  double Breite = 0;
         //   double z = 0;
          //  int a = Menu_Tree(MobileID, out Lange, out Breite, out z);
            Menu_Tree(MobileID, out La, out Br, out zz);
            string[] buffer = new string[2];
            using (System.IO.StreamWriter file = new System.IO.StreamWriter(ProgramPfad))
            {
                double x_robot = 10.0;   // to be modified when robot works in cm
                double y_robot = 20.0;   // to be modified when robot works in cm
                double z_robot = 30.0;   // to be modified when robot works in cm

                double x_distance = 10.0;  // After Measurements between robot and cradle in cm
                double y_distance = 5.0;   // After Measurements between robot and cradle in cm

                // Convert Lange, Breite, z into cm


                file.WriteLine("PROJECT;SEQUENCE;STEP;XPOS;YPOS;ZPOS;WRIST;WRISTROT;SPEED;PAUSE");

              

                    buffer[0] = (MobileID + ";" + 1 + ";" + 1 + ";" + x_robot + ";" + y_robot + ";" + z_robot + ";" + 71 + ";" + -51 + ";" + 30 + ";" + 400);
                    buffer[1] = (MobileID + ";" + 2 + ";" + 1 + ";" + (x_robot + x_distance) + ";" + (y_robot + y_distance) + ";" + z_robot + ";" + 71 + ";" + -51 + ";" + 30 + ";" + 400);
                   
                    file.WriteLine(buffer[0]);
                    file.WriteLine(buffer[1]);

               

            }


        }

Then The second method is adding lines on the csv file.... This is where i should aadd all the coordinates according to the mobile ID.. but what it does now.,.. It adds only one value which is the value of the first press key


  // Add Line to csv
        static void addlinecsv(int MobileID) {
            string[] buffer = new string[1];
            double La=0;
            double Br=0;
            double zz=0;
            string ProgramPfad = (@"C:\Robotron\MobileRobotDaten\" + MobileID + ".csv");
            Menu_Tree(MobileID, out La, out Br, out zz);
            buffer[0] = (MobileID + ";" + 3 + ";" + 1 + ";" + La + ";" + Br + ";" + zz + ";" + 71 + ";" + -51 + ";" + 30 + ";" + 400);
            File.AppendAllText(ProgramPfad, buffer[0]);
       
        }    


Then the third method is to finish the csv file by writting a fixed line

  static void finishcsv(int MobileID)
        {
            string[] buffer = new string[1];
            double La = 0;
            double Br = 0;
            double zz = 0;
            double x_robot = 10.0;   // to be modified when robot works in cm
            double y_robot = 20.0;   // to be modified when robot works in cm
            double z_robot = 30.0;   // to be modified when robot works in cm
            string ProgramPfad = (@"C:\Robotron\MobileRobotDaten\" + MobileID + ".csv");
            Menu_Tree(MobileID, out La, out Br, out zz);
            buffer[0] = (MobileID + ";" + 4 + ";" + 1 + ";" + x_robot + ";" + y_robot + ";" + z_robot + ";" + 71 + ";" + -51 + ";" + 30 + ";" + 400);
            File.AppendAllText(ProgramPfad, buffer[0]);

        }    

The problem now is in the second method.. it does not add all the coordinates.. It only adds the first coordinate of the first PressKey.. and the third method does not add anything yet

what about writing the displayed coordinates in the csv file. I made another method that generates csv file, but my problem is that i want to write the data for press key and touch screen so my buffer size should be the size of menuActionList but without the Wait... do u understand me??..

Here is the method... but how can i specify to write the data of all the Actions except wait

  static void generatecsv(int MobileID)
        {
            string ProgramPfad = (@"C:\Robotron\MobileRobotDaten\" + MobileID + ".csv");
            double La=0;
            double Br=0;
            double zz=0;

            Menu_Tree(MobileID, out La, out Br, out zz);
            string[] buffer = new string[5];
            using (System.IO.StreamWriter file = new System.IO.StreamWriter(ProgramPfad))
            {
                double x_robot = 10.0;   // to be modified when robot works in cm
                double y_robot = 20.0;   // to be modified when robot works in cm
                double z_robot = 30.0;   // to be modified when robot works in cm

                double x_distance = 10.0;  // After Measurements between robot and cradle in cm
                double y_distance = 5.0;   // After Measurements between robot and cradle in cm

                // Convert Lange, Breite, z into cm


                file.WriteLine("PROJECT;SEQUENCE;STEP;XPOS;YPOS;ZPOS;WRIST;WRISTROT;SPEED;PAUSE");
                for (int k = 0; k < 4; k++)
                {

                    buffer[k] = (MobileID + ";" + 1 + ";" + 1 + ";" + x_robot + ";" + y_robot + ";" + z_robot + ";" + 71 + ";" + -51 + ";" + 30 + ";" + 400);
                    buffer[k+1] = (MobileID + ";" + 2 + ";" + 1 + ";" + x_robot + x_distance + ";" + y_robot + y_distance + ";" + z_robot + ";" + 71 + ";" + -51 + ";" + 30 + ";" + 400);
                    buffer[k+2] = (MobileID + ";" + 3 + ";" + 1 + ";" + La + ";" + Br + ";" + zz + ";" + 71 + ";" + -51 + ";" + 30 + ";" + 400);
                    buffer[k+3] = (MobileID + ";" + 4 + ";" + 1 + ";" + x_robot + ";" + y_robot + ";" + z_robot + ";" + 71 + ";" + -51 + ";" + 30 + ";" + 400);
                    file.WriteLine(buffer[k]);

                }

            }


        }

According to the Mobile Id entered by the user. It should check the three if conditions and write the x,y,z of the corresponding letter such as user_key 1 for that mobile ID.

Yeah, I've decompressed the RAR files and I'm looking at them now.

On the "PressKey" point, I see that the column before this shows something like 'user_key1'. However, there could be several matches of this in the Tastatur.csv file. So do you want to find all matches or is there some way of identifying a single one which you want?

Also, there's definitely a problem with the code as it stands:

 
As you already have the relevant columns for MenuTree.csv, you should be iterating through the lines in Tastatur.csv  (i.e. TT) looking for a match.

CSV Files

Look, There are 3 cases

The first if condition is when it finds TouchScreen.. It should display the X,Y of the percentage values.. It does that at the moment

The second if condition is when it finds pressKey.. It should get the X,Y,Z coordinates from another csv file for the corresponding Letter in the column before the Presskey.. I did it but I wanna double check with you..

The third if condition is when it finds Wait.. It should do nothing..

Then after these 3 if conditions it opens a new csv file and writes the x,y,Z in it...

SO ITS NOT IMPORTANT TO DISPLAY THE VALUES AS ITS MORE IMPORTANT TO WRITE THEM IN THE CSV FILE CORRECTLY:: i WAS DISPLAYING IT IN THE FIRST STEP TO SEE IF ITS CORRECT     ..

When i copy paste the whole method here it does not work.. I will attach it but please confirm if u received it.. This is my last question for you. I really appreciate ur help...

The method is attached

Just to be clear, so could there be multiple 'TouchScreen' lines in the file each of which will generate a Lange and Breite value?

If so, would you want to associate some other variable with these values, to identify where they came from, when printing them out?

So the Lists only have one value each and that value will be at index 0.

If that's the case, then these lines:

This is the method that gets length and width...

Nothing has been uploaded but, fortunately, I saw the code (and copied it so I could format it into a readable fashion) before you edited the post. Here it is for the benefit of other members:

if (MenuNameList.Count() > 0)        
{            
   Console.WriteLine("The Corresponding MenuTree Information is: ");                
   for (int i = 0; i < MenuNameList.Count; i++)            
   {                
       Console.WriteLine("  {0} : {1} : {2}: {3}", MenuTreeViewList[i], MenuNameList[i], MenuInfoList[i], MenuActionList[i]);                
       //  Console.WriteLine("Please select the EndKnot you want to choose");          
       //   Console.ReadKey();                  
       if (MenuActionList.Contains("TouchScreen") && MenuInfoList[i].Contains("%"))                
       {                      
           string a = MenuInfoList[i];                      
           string[] words = a.Split('%');                      
           List L;                    
           List W;                      
           GetLengthWidth(MobileID, out L, out W);                    
           double X=Convert.ToDouble(words[0]);                    
           double Y = Convert.ToDouble(words[1]);                      
           double Lange = Math.Abs(L[i]) * X / 100;                    
           double Breite = Math.Abs(W[i]) * Y / 100;                            
           Console.WriteLine(Lange);

First of all, I wondered whether this line:

  if (MenuActionList.Contains("TouchScreen") && MenuInfoList[i].Contains("%"))

should be

  if (MenuActionList[i].Contains("TouchScreen") && MenuInfoList[i].Contains("%"))

Secondly, are you wanting here to multiply EVERY member of the Lists, L and W, by X/100 and Y/100 respectively or just the L[i] and W[i] elements?

If it's the latter, are you sure that the 'i' being used here (i.e. the index of the 'TouchScreen' line in the file) will correspond to the 'i' th element of the Lists?

If it doesn't then this could be reason for the error.
