Question

Im playing around with TryParse()

But lets say the parsing fails, then returns false, and … nothing.. Is there a way to get info back about what failed the parsing?

I saw something like that at codeproject, but i didnt really understand it.

Thanks 🙂

No, there’s no way of getting that information from the normal .NET routines. You could check for a few things manually:

• Try parsing the number as a decimal. If that works, but parsing as an integer doesn’t, then it’s either out of the range of the integer, or it’s not an integer.
• Look for non-decimal, non +/-, non-decimal-point characters
• Check whether it’s an empty string

You haven’t said what you’re trying to parse (integer, double etc) or what options you want (allow hex, thousands separators etc) which makes it harder to give a good list of things to check.
