Min and Max operations on enum values

Question

Using C#, how can I take the min or max of two enum values?

For example, if I have

enum Permissions
{
    None,
    Read,
    Write,
    Full
}

is there a method that lets me do Helper.Max(Permissions.Read, Permissions.Full) and get Permissions.Full, for example?

Enums implement IComparable so you can use:

public static T Min<T>(T a, T b) where T : IComparable
{
    return a.CompareTo(b) <= 0 ? a : b;
}
