Storing Value of Text Box to int Variable in Windows Form

Question

_{Thursday, October 8, 2009 5:11 PM}

I want this text box to be numerical values only, and I want it to store the value that is typed into it.

I tried an Int32.Parse of the text box, but that didn't work.

How can I do this?

I'm using Visual Studio 2008 with C#.

I'd greatly appreciate it.

You will need to do

     int value = Int32.Parse(textBox.Text );

However, if the user types "a" into the text box, it'll raise an exception.  It might be better to put error handling in here:

     int value;
     if (!Int32.TryParse(textBox.Text, out value))
     {
         // The text box isn't a valid number - tell the user!
         MessageBox.Show("Please enter a valid number!");
     }

Did you try using the toString() method?

Thank you very much sir. I wouldn't have remembered to do the error handling either.
