Tell if string to double/float/int/short/byte is out of range

Question

I have the following:

string outOfRange = "2147483648"; // +1 over int.MaxValue

Obviously if you have anything other than a number this will fail:

var defaultValue = 0;
int.TryParse(outOfRange, out defaultValue);

My question is, since this IS a number, and it WILL fail when you int.TryParse(), how do you tell that it failed because the string was out of the bounds of the container it's stored in?

Answer 1

I'd go with the Try/Catch solution for this scenario.

        string outOfRange = "2147483648";
        try
        {
            int.Parse(outOfRange);
        }
        catch (OverflowException oex)
        {

        }
        catch (Exception ex)
        { }

I know that most people here would recommend avoiding this but sometimes we just have to use it (or we don't have to but it would just save us a lot of time).
here's a little post about the efficiency of Try/Catch.

Answer 2

can parse to decimal and then check range, avoids try/catch

string s = "2147483648";
decimal.Parse(s) > int.MaxValue;
