Byte enum comparison in C#

Question

Given this enum

public enum UserStatus : byte
{
    Approved = 1,
    Locked = 2,
    Expire = 3
}

why does this check always return false

Answer 1

The first thing any Equals implementation usually checks is: "is this the right type". And UserStatus is not the same as byte.

(actually, this only happens because you have boxed the items via your incompatible use of Equals; at the IL level they are indistinguishable until boxed)

You must compare them as items of the same type. To borrow some code from byte:

public override bool Equals(object obj)
{
    return ((obj is byte) && (this == ((byte) obj)));
}
