Question

I want to convert a value entered in a textBox (which can only be empty or “1” or “2” or “3”) to an integer. If empty I want it to be 0, otherwise, it’s corresponding value (1, 2, or 3).

Is there a way to do that like:

MyIntVal = TryConvertToInt(textBox1.Text, 0);

…where an empty string or anything not readily convertible to an int would default to 0?

Answer 1

int result = 0;
int.TryParse(stringValue, out result);

Will default to 0 if stringValue cannot be parsed to an int.
