C# non-boxing conversion of generic enum to int?

Question

Given a generic parameter TEnum which always will be an enum type, is there any way to cast from TEnum to int without boxing/unboxing?

See this example code. This w

...I'm even 'later' : )

but just to extend on the previous post (Michael B), which did all the interesting work

and got me interested into making a wrapper for a generic case (if you want to cast generic to enum actually)

...and optimized a bit... (note: the main point is to use 'as' on Func<>/delegates instead - as Enum, value types do not allow it)

public static class Identity
{
    public static readonly Func Cast = (Func)((x) => x) as Func;
}

...and you can use it like this...

enum FamilyRelation { None, Father, Mother, Brother, Sister, };
class FamilyMember
{
    public FamilyRelation Relation { get; set; }
    public FamilyMember(FamilyRelation relation)
    {
        this.Relation = relation;
    }
}
class Program
{
    static void Main(string[] args)
    {
        FamilyMember member = Create(FamilyRelation.Sister);
    }
    static T Create(P value)
    {
        if (typeof(T).Equals(typeof(FamilyMember)) && typeof(P).Equals(typeof(FamilyRelation)))
        {
            FamilyRelation rel = Identity.Cast(value);
            return (T)(object)new FamilyMember(rel);
        }
        throw new NotImplementedException();
    }
}

...for (int) - just (int)rel
