The problem is that a string such as Green can't be converted to an integer. What you need to do is to convert it to an EnumColor value instead using the Enum.Parse method: http://msdn.microsoft.com/en-us/library/kxydatf9(v=vs.100).aspx Try this instead: using System; namespace Test { class Program { enum EnumColor: int { Red=0Green=1Blue=2 }; static void Main(string[]args) { Console.WriteLine(Please Enter a Color Name); EnumColor x = (EnumColor)Enum.Parse(typeof(EnumColor) Console.ReadLine() true); switch(x) { case EnumColor.Red: { Console.WriteLine(Your Choise is Red); break; } case EnumColor.Green: { Console.WriteLine(Your Choise is Green); break; } case EnumColor.Blue: { Console.WriteLine(Your Choise is Blue); break; } } } } }
