How do I overload an operator for an enumeration in C#?

Question

I have an enumerated type that I would like to define the >, <, >=, and <= operators for. I know that these o

As other mentioned before, one cannot override operators on Enums, but you can do it on struct. See an example below. Let me know if it helped:

public struct SizeType
{
    private int InternalValue { get; set; }

    public static readonly int Small = 0;
    public static readonly int Medium = 1;
    public static readonly int Large = 2;
    public static readonly int ExtraLarge = 3;

    public override bool Equals(object obj)
    {
        SizeType otherObj = (SizeType)obj;
        return otherObj.InternalValue.Equals(this.InternalValue);
    }

    public static bool operator >(SizeType left, SizeType right)
    {
        return (left.InternalValue > right.InternalValue);
    }

    public static bool operator <(SizeType left, SizeType right)
    {
        return (left.InternalValue < right.InternalValue);
    }

    public static implicit operator SizeType(int otherType)
    {
        return new SizeType
        {
            InternalValue = otherType
        };
    }
}

public class test11
{
    void myTest()
    {
        SizeType smallSize = SizeType.Small;
        SizeType largeType = SizeType.Large;
        if (smallSize > largeType)
        {
            Console.WriteLine("small is greater than large");
        }
    }
}
