Get int value from enum in C#

Question

I have a class called Questions (plural). In this class there is an enum called Question (singular) which looks like this.

public e

I came up with this extension method that includes current language features. By using dynamic, I don't need to make this a generic method and specify the type which keeps the invocation simpler and consistent:

public static class EnumEx
{
    public static dynamic Value(this Enum e)
    {
        switch (e.GetTypeCode())
        {
            case TypeCode.Byte:
            {
                return (byte) (IConvertible) e;
            }

            case TypeCode.Int16:
            {
                return (short) (IConvertible) e;
            }

            case TypeCode.Int32:
            {
                return (int) (IConvertible) e;
            }

            case TypeCode.Int64:
            {
                return (long) (IConvertible) e;
            }

            case TypeCode.UInt16:
            {
                return (ushort) (IConvertible) e;
            }

            case TypeCode.UInt32:
            {
                return (uint) (IConvertible) e;
            }

            case TypeCode.UInt64:
            {
                return (ulong) (IConvertible) e;
            }

            case TypeCode.SByte:
            {
                return (sbyte) (IConvertible) e;
            }
        }

        return 0;
    }
