    Enum comparison not working.

    Code:
    using System;
    using System.Collections.Generic;
    using System.Linq;
    using System.Text;
    
    namespace ConsoleApplication1
    {
        class Program
        {
            public enum TagLabels : uint
            {
                TurnLeft = 0x0000000000000000000030A38DB1,
                TurnRight = 0x00000000000000000000307346CC,
                LiftApproach = 0x0000000000000000000012107A8D
            }
            
            static void Main(string[] args)
            {
                TagLabels friend;
                string Tag = TagLabels.TurnRight.ToString();
                string actual, returned;
                actual = "0x0000000000000000000012107A8D";
                returned = "0x0000000000000000000012107A8D";
                
                if (actual == TagLabels.LiftApproach.ToString() )
                    Console.WriteLine("equivalent");
    
                friend = (TagLabels)Enum.Parse(typeof(TagLabels), actual);
                Console.Write("Attempting to convert: ");
                Console.WriteLine(actual);
                
                Console.Read();
            }
        }
    }
    Can some one tell me what's wrong with the section in bold please?
    I have no idea why it wont work.

    Because
    Code:
    TagLabels.LiftApproach.ToString()
    is LiftApproach. Check your debugger. Also your method of comparison is pretty wierd, why cant you just compare one enum to another, or an enum to the number value. Also why are you preceeding so many meaningless zeros?

    Because that's the return of a possible list of devices from a reader... Also I solved it. I needed to compare a return to the enum list so that I can use it to set another variable in the class.

    His point with the zeros comment was that the compiler ignores them completely. These are equivalent:

    Code:
                TurnLeft = 0x0000000000000000000030A38DB1,
                TurnRight = 0x00000000000000000000307346CC,
                LiftApproach = 0x0000000000000000000012107A8D

    Code:
                TurnLeft = 0x30A38DB1,
                TurnRight = 0x307346CC,
                LiftApproach = 0x12107A8D
    There's no difference between the two at all. They both are the exact same value to the compiler.
