Adding Some Armor to Methods Using Passed Enums

In my previous post I demonstrated the fallibility of methods that take enumerations as parameters. As a defense you can use the Enum.IsDefined() method to check the validity of passed enum values:

static void SafeColorToString(EnumLegalColor color) {
           
   if(!Enum.IsDefined(typeof(EnumLegalColor), color))
      throw new Exception(string.Format("{0} is not a valid EnumLegalColor", (int) color));
               
   Console.WriteLine(color.ToString());               
}
