Code: Select all

int num1  = Int.Parse(textBox1.Text);
int num2  = Int.Parse(textBox2.Text);
int add   = num1 + num2; 

now that you know this, you can do directly:

Code: Select all

int add = Int.Parse(textBox1.Text) + Int.Parse(textBox2.Text);

Also, don't forget to validate the key on input in your textbox...I think it's the propertie OnKeyPress(Object e)
if the char entered is higher than 47 and lower than 58
txtbox.text = txtbox.text + e.toString();

Something like this...

Also you can do this:

Code: Select all

int num1=Convert.ToInt32(textbox1.text)

If is doesn't work then try ToInt16 or 64.
