Description Caronte 2014-12-11 12:36:16 UTC
When i try to overflow a int data type using int.Parse, this doesn't happen.

Ex:
System.UInt32 x = System.UInt32.MaxValue + System.UInt32.Parse("1");
int y = int.MaxValue + int.Parse("1");

//returns 0

short.MaxValue implicity converts short type to int.

Ex:
short x = short.MaxValue - short.Parse("1");

// returns Error CS0266.

I think that there are more problems with doubles, decimals, etc, too.

Please, excuse me my english.

Regards.

that's expected because it's running un unchecked context.

You probably want to do instead something like

System.UInt32 x = checked (System.UInt32.MaxValue + System.UInt32.Parse("1"));
