reading from text file: each line in seperate array?

vin lantwert

Hello,

I am very new to programming so please bare with me. I need to make a program that can read a .txt file and store each line in an array, so i can use some of its contents later (store in a database). Is this possible? and how would i go about doing that. I have tried with the streamreader and then making each line a list item, but then it wont let me convert to array. i would really like some help here, TNX!

            }

            //Show First Line's 3 Words in Text Box
            int count = 0;
            foreach (string str in ArraysWithWords[0])
            {
                if (count <3)
                {
                    textBox1.Text += str;

so the above piece of code puts all words in ArraysWithWords right? how would i show the 3 word in a textbox? if i try it doesnt work:
bestand = openFileDialog1.FileName;
            string[] allLines = File.ReadAllLines(bestand);

            List ArraysWithWords = new List();

            foreach (string str in allLines)
            {

                string[] Words = str.Split(' ');

                ArraysWithWords.Add(Words);

            }
            textBox1.Text = ArraysWithWords[3];

        }

Thanks, thats very kind of you. what i want is this:
i have a text file that gets automatically generated by a website.
in this file there is a lot of data i need.
what i want is to read the file and have an array for each individual line
the text file size differs with each file.
is this enough info?

I have now coded this, it works but its ugky, is there no other way i can do this?

string[] readtext = File.ReadAllLines(bestand, Encoding.UTF8);


            textBox1.Text = readtext[1];

            string regel1 = textBox1.Text;

            string[] aRegel1 = regel1.Split(' ');

Now i have to use the textbox to convert it to the string, but this would mean that i have to make a textbox for every line i want in an array.

Hi,

When I try the above i get an error message saying cannot implicitly convert string[] to string. This is my code:

openFileDialog1.ShowDialog();
            ChosenFile = openFileDialog1.FileName;

            string[] readtext = File.ReadAllLines(ChosenFile, Encoding.UTF8);

            string[] linesArray = new string[readtext.Length];

            int counter = 0;

            foreach (string line in readtext)
            {
                string[] _wordsArray = line.Split(' ');
                linesArray[counter] = _wordsArray;
                counter++;
            }
Thanks for your help sofar

just run on the string[] and build whatever you need:

 string[] linesArray = new string[_array.Length];

int counter = 0;

 foreach(string line in _array)
 {
   string[] _wordsArray = line.Split(' ');
   linesArray[counter] = _wordsArray;
   counter++;
}

Hi Thanks,

This works partly, what happens now is each line is one item in the array, what i actually need is one array per line where the items in the array are the single words. is this possible?

you can use this

         // Open the file to read from.
        string[] readText = File.ReadAllLines(path, Encoding.UTF8);
