Question

I’m trying to build Custom Membership Provider. I would like to capture additional information (First Name and Last Name) during the registration and I’m not using usernames (email is a login).

In my custom Membership Provider I’m trying to overload CreateUser method like this:

    public override MyMembershipUser CreateUser(string firstName, string lastName, 
                                       string email, string password)
    {
        ...
    }

But when I want to call it from the Account controller:

    [HttpPost]
    public ActionResult Register(RegisterModel model)
    {
        if (ModelState.IsValid)
        {
            // Attempt to register the user
            MembershipCreateStatus createStatus;
            Membership.CreateUser(model.FirstName, model.LastName, 
                                  model.Email, model.Password);

            if (createStatus == MembershipCreateStatus.Success)
            {
                return RedirectToAction("Index", "Home");
            }
            else
            {
                ModelState.AddModelError("", ErrorCodeToString(createStatus));
            }
        }

        // If we got this far, something failed, redisplay form
        return View(model);
    }

I get the error stating that “No overload for method takes 4 arguments”.

How do I call my custom CreateUser method from Custom Membership Provider class?

Thank you!

Answer 1

Isn’t it obvious? You’re referencing Membership, not MyMembershipProvider when you call Membership.CreateUser.

It looks like Membership is a static class that internally calls into your membership provider, so there is no real way to change this other than creating your own “MyMembership” static class that does the same thing. Since you can’t inherit from static classes, you would have to either call into Membership.XXX from your static version, or implement the functionality yourself.

Your own MyMembership class could then have any methods you wanted it to have.

Another option would be to do something like this:

((MyMembershipProvider)Membership.Provider).CreateUser()

I don’t like this approach though because it requires you to remember to call the provider CreateUser rather than the Membership.CreateUser. Plus, casting is often a code smell (unless encapsulated, which is why i recommended your own MyMembership static class).
