Implementing Custom Membership Provider Membership User Issues

Question

I am trying to implement a custom membership provider and want to change the GetUser method. The problem is that GetUser returns MembershipUser and I want to return MyMembershipUser which has two additional properties FirstName and LastName. I can create a new method in my membership provider which returns MyMembershipUser but then I think it won't make any sense.

How would I go about doing this?

Answer 1

That would defeat the purpose of the Membership classes. Do something like this if you need to access other properties:

var user = Membership.GetUser(userName, true) as MyMembershipUser;

Really you should have a separate Profile class that handles things that MembershipUser does not provide.

var profile = Profile.GetProfile(Membership.GetUser(userName, true));

Answer 2

If MembershipUser is the base class of MyMembershipUser then you can return instances of MyMembershipUser even though the return type of GetUser() is MembershipUser and then, if necessary, cast them back to MyMembershipUser (but do you really need to do that?)

BTW, this is an example of polymorphism.

Answer 3

You should go for Profile Provider. check this link, you have either SqlStoredProcedureProfileProvider and SqlTableProfileProvider, this way you have ability to store Profile data “in the clear” in the database, letting you query the db whenever u want.

"you can implement whatever business logic you need in the stored procedures to map the Profile data to your own database schema and database logic."
