How can I test if a string is a number

I want to test in my program if the user input is a number, because I don’t want the program to crash.

I’ve already tried

int.Parse(ipt);

but this doesn’t work if the user puts in a non-number.

>Solution :

You can use this:

int outInt;
bool isNumeric = int.TryParse(ipt, out outInt);
