It's so fun to discover new, simple things in the .NET Framework that make your life easier. Did you know you can call Int32.Parse on a string that contains a hex value and it will convert to decimal for you? If you did, I'm sure I won't be the last person to find this and think it is pretty darn cool. :-)
int
x = System.Int32.Parse("A",
NumberStyles.AllowHexSpecifier);
Console.WriteLine(x);
