int.TryParse(, out ); code example
Example 1: c# how to convert string to int
var myInt = int.Parse("123"); // this one throw exception if the argument is not a number
var successfullyParsed = int.TryParse("123", out convertedInt); //this returns true if the convertion has been successfully done (integer is stored in "convertedInt"), otherwise false.
Example 2: c sharp tryparse
// Any Parse() function has a TryParse function, which returns
// 'true' on a success and 'false' on a failure. On a succes
// it also saves the conerted value in the second parameter.
string value = "160"
int number;
bool success = Int32.TryParse(value, out number);
// success = true
// number = 160
