To loop or not...?

Hi there!
I am stuck and looking for help. I have a text box in which I ask the user up to what number he/she would like to start, end the count in the range of 1 to 100. If the input is 3,25 or 7,12,52 how would I implement the loop?



  • I'm still having a little difficulty understanding your question but I'll answer it to the best of my ability.

    You have a TextBox control on a windows form. The user types in "3,25" into the textbox. You want 3 to be your starting number and you want to look until 25 (the end count).

    If your user types "7,12,52" into the textbox, this is not a valid input because you have an extra number. So tell your user he made a mistake and to try again.

    string Input = textBox1.Text;
    string[] Splitted = Input.Split(new char[] {','}, StringSplitOptions.RemoveEmptyEntries);
    if (Splitted.Length == 2)
    int Start = Int32.Parse(Splitted[0]);
    int End = Int32.Parse(Splitted[1]);
    for (int i = Start; i < End; i++)
    // do stuff in this loop
    MessageBox.Show("You can only have 2 numbers in the textbox separated by one comma. Please try again.", "Get it right");
    // Computer.CallBSOD();
