I am messing around trying to understand Classes and I am pretty sure I understand them now, but I am trying to make a Windows Form that has 2 text boxes where the user inserts a number in each one and then they get passed to a classes that adds the 2 together. I am taking it that textboxes are not considered INTs which makes sence, but how to I convert them to an INT?
thanks for any help.

1st to get the string values in the textboxes
string text = textbox1.Text;
then to convert it to integer
int num = int.Parse(text);
but be sure that what you've type there are numbers because this may throw exception

put a try catch block
int i = 0;
try
{
i=int.Parse(txtMyText.Text);
}
catch(Exception)
{
MessageBox.Show("Please put only numbers");
}
