How to change username using mvc4 and simplemembership [duplicate]

问题

Why is it that you can't change a simplemembership username. I've tried

MembershipUser memUser = Membership.GetUser(existingUser);
memUser.UserName = model.UserName;
Membership.UpdateUser(memUser);

I get that MembershipUser.UserName is read only. There are no other available methods for changing the username.

Is there a way around this problem?

Edit: New problem. When the line

 var confirmationToken = WebSecurity.CreateUserAndAccount(model.UserName, Request["Password"], new { NameFirst = model.NameFirst, NameLast = model.NameLast, ContactId = newContact.ContactId },true);

is run, I get a MembershipCreateUserException and says the username is already in use (it really isn't). It manages to add the user to my UserSecurity table(UserProfile) but doesn't add it to the membership table. It's attempting to add the user in the webpages_Membership table and not the UserMembership table I created.

回答1:

You may not be able to edit the users name with the MembershipProvider. In SimpleMembership you have to add a UserProfile table to your Model, where the username is stored.

You specify the table on initialization:

WebSecurity.InitializeDatabaseConnection("DBname", "UserProfileTable", "IdColumn", "UsernameColumn", autoCreateTables: true);
