在 asp.net 網頁中嘗試 WebSecurity.CreateAccount 時遇到錯誤“提供程序遇到未知錯誤”

我是 asp.net 的新手。我正在嘗試使用 WebMatrix 創建一個簡單的登錄和註冊網頁。但是當我嘗試創建帳戶時出現以下錯誤：

---

The Provider encountered an unknown error.

任何幫助表示讚賞。謝謝。

務必：

1. 首先創建使用者記錄
2. 呼叫 WebMatrix 以創建使用者帳戶。

以下是我的程式碼，它解決了您遇到的相同問題：

public ActionResult SignUp(SignUpModel model)
   {
       if (ModelState.IsValid)
       {
           using (MorphometryContext context = new MorphometryContext())
           {
               User user = new User
               {
                   Email = model.Email,
                   FirstName = model.FirstName,
                   LastName = model.LastName,
                   Username = model.UserName
               };
               context.Users.Add(user);
               context.SaveChanges();
           }

           // Attempt to register the user
           try
           {
               WebSecurity.CreateAccount(model.UserName, model.Password);
           }
           catch (MembershipCreateUserException e)
           {
               ModelState.AddModelError("", ErrorCodeToString(e.StatusCode));
               return View();
           }

           WebSecurity.Login(model.UserName, model.Password);
           return RedirectToAction("Index", "Projects");
       }

此外，您不想 Respoonse.Redirect 到 .cshtml 文件。相反，您應該返回一個 RedirectToAction 並傳入 Action 和 Controller 名稱。

我只是遇到了同樣的問題……我正在使用

WebSecurity.CreateAccount(model.UserName, model.Password);

及以上產生的問題..

然後我嘗試了：

WebSecurity.CreateAccountAndUser(model.UserName, model.Password);

並發現我缺少使用者表 (UserProfile) 的其他必填欄位。以下為我工作：

WebSecurity.CreateAccountAndUser(model.UserName, model.Password, new {RequiredColumn1 = Value1, RequiredColumn2 = Value 2, ...... });

文章很舊，但希望這可以幫助其他人..
