Best way to handle Integer overflow in C#?

Asked 2010-06-02T04:13:03.450

Handling integer overflow is a common task, but what's the best way to handle it in C#? Is there some syntactic sugar to make it simpler than with other languages? Or is this really the best way?

int x = foo();
int test = x * common;
if(test / common != x)
    Console.WriteLine("oh noes!");
else
    Console.WriteLine("safe!");

Sometimes, the simplest way is the best way. I can't think a better way to write what you wrote, but you can short it to:

int x = foo();

if ((x * common) / common != x)
    Console.WriteLine("oh noes!");
else
    Console.WriteLine("safe!");

Note that I didn't remove the x variable because it'd be foolish to call the foo() three times.
