Cicle for auto assign TextBox to variables, how to do it?

Ricardo Cunha

Hey, in class the teacher told us to do some programs, some of them with many TextBox and I tried hard to read the TextBoxes and save them onto a array inside a for, so that I didn't had to assign every single one of them manually, but in the end that was the result, a very stupid way of programming I think, I asked my teacher and even she could come up with a way of doing that...

All the textboxes are named "txt*" were * is 1, then 2, 3.... You get the idea, so I thought, well gonna save a string were it was "txt" + x(variable that is incremented) + ".Text"(Because if I don't put a real TextBox name it doesn't recognise it, if instead of putting txt1 I put txtx, txt(x), txt + x or other way in the end I couldn't put .Text, so I made that string) but without result, as it didn't accept the string.

For Example:
Instead of doing:
Vec[0] = Convert.ToInt32(txt1.Text);
Vec[1] = Convert.ToInt32(txt2.Text);
Vec[2] = Convert.ToInt32(txt3.Text);
Vec[3] = Convert.ToInt32(txt4.Text);
Vec[4] = Convert.ToInt32(txt5.Text);

I want some cicle that could do something like:
int x = 1;

for (int i = 0; i < 5; i++)
{
Vec[i] = Covert.ToInt32(txt(x).Text);
x++;
}

Or instead a way to convert a string to the TextBox name would be appreciated...

I couldn't find a way to do something like that, please help me...

Sorry but, I haven't had much experience with object-oriented, because I've just began my course's second year... If either of you wouldn't mind could you explain to me how to apply that? I've tried but without success... for example a program that would read 10 TextBox with int numbers and then say what's the bigger number, I think that it isn't much complicated to do, and it would help me greatly...

here is the better aligned code, which is a bit more flexible on the array Length

 private void button1_Click(object sender, EventArgs e)
        {
            List<String> txtStrings = new List<String>();
            List<TextBox> txtList = new List<TextBox>();
            foreach (Control c in this.Controls)
            {
                if (c is TextBox)
                {
                    txtList.Add((TextBox)c);
                    txtStrings.Add( ((TextBox)c).Text);
                }
             }
        }

Friend,

Here is Code for your Logic :)

dont Forget to mark "Do you like answer" it will give me some credits :)

private void button1_Click(object sender, EventArgs e)
        {
            int ArrSize =4;
            string[] x = new string[ArrSize];
            int i;
            List<TextBox> txtList = new List<TextBox>();
            foreach (Control c in this.Controls)
            {
                if (c is TextBox)
                {
                    txtList.Add((TextBox)c);
                }
             }

            i = ArrSize-1;
            foreach (TextBox t in txtList)
            {
                x[i] = t.Text;
                i--;
            }
        }
