Enum Boxing and Equality

Question

Why does this return False

    public enum Directions { Up, Down, Left, Right }

    static void Main(string[] args)
    {
        bool matches = IsOneOf(Directi         


        

Answer 1

As JB says, boxing. You can see this by changing from Enum to Directions:

public static bool IsOneOf(Directions self, params Directions[] values)
{
    foreach (var value in values)
        if (self == value)
            return true;
    return false;
}

true is returned.
