c# - .net MVC与数据库的简单成员身份验证

使用.net mvc 4中的代码优先实体框架，我创建了一个新的web应用程序，并用如下所示的对象填充了数据库。

 public class GratifyGamingContext : DbContext
{
    public DbSet<Game> Games { get; set; }
    public DbSet<Genre> Genres { get; set; }
    public DbSet<UserProfile> UserRepository { get; set; }
}

我想使用我的userrepository表，而不是accountmodel.cs中的内置usercontext类来访问我的用户帐户，因为我无法使用现有的dbcontext来完成这项工作。

    public class UsersContext : DbContext
{
    public UsersContext()
        : base("DefaultConnection")
    {
    }

    public DbSet<UserProfile> UserProfiles { get; set; }
}

[Table("UserProfile")]
public class UserProfile
{
    [Key]
    [DatabaseGeneratedAttribute(DatabaseGeneratedOption.Identity)]
    public int UserId { get; set; }
    public string UserName { get; set; }
}

从initializeSimpleMembershipAttribute.cs构造SimpleMembershipInitializer对象时，我的程序总是崩溃。我已经注释掉了我认为应该无关紧要的代码。

    [AttributeUsage(AttributeTargets.Class | AttributeTargets.Method, AllowMultiple = false, Inherited = true)]
public sealed class InitializeSimpleMembershipAttribute : ActionFilterAttribute
{
    private static SimpleMembershipInitializer _initializer;
    private static object _initializerLock = new object();
    private static bool _isInitialized;

    public override void OnActionExecuting(ActionExecutingContext filterContext)
    {
        // Ensure ASP.NET Simple Membership is initialized only once per app start
        LazyInitializer.EnsureInitialized(ref _initializer, ref _isInitialized, ref _initializerLock);
    }

    private class SimpleMembershipInitializer
    {
        public SimpleMembershipInitializer()
        {
            //Database.SetInitializer<UsersContext>(null);

            try
            {
                using (var context = new GratifyGamingContext())
                {
                    if (!context.Database.Exists())
                    {
                        // Create the SimpleMembership database without Entity Framework migration schema
                        ((IObjectContextAdapter)context).ObjectContext.CreateDatabase();
                    }
                }

                WebSecurity.InitializeDatabaseConnection("DefaultConnection", "UserProfile", "UserId", "UserName", autoCreateTables: true);
            }
            catch (Exception ex)
            {
                throw new InvalidOperationException("The ASP.NET Simple Membership database could not be initialized. For more information, please see http://go.microsoft.com/fwlink/?LinkId=256588", ex);
            }
        }
    }
}

我的连接字符串如下：

<add name="DefaultConnection" connectionString="Data Source=.\SQLEXPRESS;Initial Catalog=aspnet-GratifyGaming-20120917185558;AttachDbFilename=|DataDirectory|\Games.mdf;Integrated Security=True" providerName="System.Data.SqlClient" />

从任何accountcontroller页调用websecurity.initializedatabaseconnect时出现以下错误：
[sqlexception（0x80131904）：文件的目录查找

如果不转到任何accountcontroller驱动的页面，则应用程序将连接到数据库。
如何将此应用程序配置为使用我的userrepository表而不是userscontext作为用户成员？

最佳答案

从web.config中的defaultconnectionstring中删除attachdbfilename

<add name="DefaultConnection" connectionString="Data Source=.\SQLEXPRESS;Initial Catalog=aspnet-GratifyGaming-20120917185558;Integrated Security=True" providerName="System.Data.SqlClient" />

在global.asax.cs中调用websecurity.initialisedatabase方法

 public class MvcApplication : System.Web.HttpApplication
{
    protected void Application_Start()
    {

        AreaRegistration.RegisterAllAreas();
        Database.SetInitializer<GratifyGamingContext>(new DatabaseInitializer());
        WebApiConfig.Register(GlobalConfiguration.Configuration);
        FilterConfig.RegisterGlobalFilters(GlobalFilters.Filters);
        RouteConfig.RegisterRoutes(RouteTable.Routes);
        BundleConfig.RegisterBundles(BundleTable.Bundles);
        AuthConfig.RegisterAuth();

        WebSecurity.InitializeDatabaseConnection(
                  connectionStringName: "DefaultConnection",
                  userTableName: "UserProfile",
                  userIdColumn: "UserID",
                  userNameColumn: "UserName",
                  autoCreateTables: true);
    }
}

在accountcontroller.cs中注释掉[InitializeSimpleMembership]

 [Authorize]
    //[InitializeSimpleMembership]
    public class AccountController : Controller
