Should “or” work with .Net4 Hasflags: enum.HasFlag(AccessRights.Read | AccessRights.Write)

Question

I am trying out the new HasFlags features, and was wondering if the following should work:

enum.HasFlag(AccessRights.Read | AccessRights.Writ

Answer 1

Alternatively, you could just reverse the order of the expression:

//returns true - a bit easier on the eye
(AccessRights.Read | AccessRights.Write).HasFlag(myAccessRights)

This will return true if you have either Read | Write access. That would be functionally equivalent to:

//also returns true - as per @Ani's answer
myAccessRights & (AccessRights.Read | AccessRights.Write) != 0

EDIT

As pointed out in the comments, The first expression will return true if myAccessRights is empty, and false if myAccessRights has more than just Read and Write.
