Is it Possible to create a Custom MembershipCreateStatus Enumeration Member

Hello everyone:

This page shows all the available Members in the MembershipCreateStatus Enumeration:

http://msdn.microsoft.com/en-us/library/system.web.security.membershipcreatestatus.aspx

Example: Lets say I needed an additional Email Validation Member, is this possible?

I try using an enum like this:

public enum MembershipCreateStatus { DuplicateUserName, DuplicateEmail, InvalidPassword,
InvalidEmail, InvalidAnswer, InvalidQuestion,
InvalidUserName, ProviderError,UserRejected, myOwnMember }

Then adding that to a switch block:

public string ValidateUserEnrty(MembershipCreateStatus status)
        {
            switch (status)
            {
              case MembershipCreateStatus.myOwnMember:
              return "Dude wheres my car.";

              default:
              return "Bad things happen to good people";
          }
    }

Of coarse I added some conditions to catch errors on the enum but it does not work. I also try overriding it but no luck, I am thinking I'll have to create a defferent validation method in addition to using the member. The truth is I am not sure what the hell I am doing.

Can I create my own member?

Thank you!

Thanks!
