与数据库.NET MVC简单成员身份验证(.net MVC Simple Membership Au

使用代码首先实体框架与.NET MVC 4我创建了一个新的Web应用程序和填充对象的数据库，如下图所示。

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

我想用我的UserRepository表，而不是内置的UserContext类从AccountModel.cs我的用户帐户访问，因为我不能让与我现有的DbContext的工作。

    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; }
}

从构建一个InitializeSimpleMembershipAttribute.cs对象SimpleMembershipInitializer当我的程序总是崩溃。 我注释掉我觉得应该是无关的代码。

    [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ConnectionString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" />

调用任何的AccountController页面WebSecurity.InitializeDatabaseConnect时，我得到了以下错误：

[SQLEXCEPTION（0x80131904）：文件目录查找 “C：\用户\虚幻\文档\ Visual Studio 2010的\项目\ GratifyGaming \ GratifyGaming.WebUI \ App_Data文件\ Games.mdf” 与操作系统错误2失败（未能检索文字此错误的原因：15105）。 无法附加文件 'C：\用户\虚幻\文档\ Visual Studio 2010的\项目\ GratifyGaming \ GratifyGaming.WebUI \ App_Data文件\ Games.mdf' 数据库 'ASPNET-GratifyGaming-20120917185558'。

[TargetInvocationException：异常已被调用的目标抛出。] System.RuntimeTypeHandle.CreateInstance（RuntimeType类型，布尔publicOnly，布尔NOCHECK，布尔逻辑canBeCached，RuntimeMethodHandleInternal＆构造函数，布尔逻辑bNeedSecurityCheck）+0

我的应用程序，否则连接到数据库，如果我没有去任何的AccountController驱动页面。 如何配置这个应用程序使用，而不是UsersContext用户会员我UserRepository表？

Answer 1:

从DefaultConnectionString在web.config中删除AttachDbFileName

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

调用Global.asax.cs中的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);
    }
}

注释[InitializeSimpleMembership]在AccountController.cs

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