Membership user in ASP.NET‎ MVC3

I have been working on ASP.Net MVC3. I created view and controller. Also, I have a model to create account.

Controller:

[HttpPost]
    public A开发者_如何学编程ctionResult LogOn(LogOnModel model, string returnUrl)
    {
        if (ModelState.IsValid)
        {
           ----> if (model.UserName == "Guven" && model.Password == "12345")
            {
                FormsAuthentication.SetAuthCookie(model.UserName, false);
                return RedirectToAction("Index", "Home");
            }
            else
            {
                ModelState.AddModelError("", "aaaaaaaaaaaaaaaaaa.");
            }
        }
        return View(model);
    }

I want to make from the database to control that the line marked on the above code.My question is:How can I do that controller?

If you're using MembershipProvider it has the ValidateUser Method.

you'll need to change your marked line to:

if (Membership.ValidateUser(model.UserName, model.Password))

If your not using MembershipProvider yet, you'll might want to implement it.

There are two primary reasons for creating a custom membership provider.

• You need to store membership information in a data source that is not supported by the membership providers included with the .NET Framework, such as a FoxPro database, an Oracle database, or other data sources.

• You need to manage membership information using a database schema that is different from the database schema used by the providers that ship with the .NET Framework. A common example of this would be membership data that already exists in a SQL Server database for a company or Web site.
