It sounds like your best option would be int.TryParse, if you encounter a string that can't be set to a valid value, it will set it to the default value for an integer (0) as well as returning a boolean so you can know this has happened.

int myInt;
if(!int.TryParse(myStringVariable, out myInt))
{
    //Invalid integer you can put something here if you like but not needed
    //myInt has been set to zero
}

//The same code without the if statement, still sets myInt
int.TryParse(myStringVariable, out myInt);
