Question

我在mvc 4应用程序中添加新角色...但每次都会出现此错误

这是我的注册方法

 //
        // POST: /Account/Register
         [AllowAnonymous]
        [HttpPost]
        public ActionResult Register(RegisterModel model)
        {
            if (ModelState.IsValid)
            {
                object x = Membership.GetUser(model.UserName);

                if (Membership.GetUser(model.UserName) == null)
                {
                    // Attempt to register the user
                    MembershipCreateStatus createStatus;
                    Membership.CreateUser(model.UserName, model.Password, model.Email, null, null, true, null,
                        out createStatus);

                    if (createStatus == MembershipCreateStatus.Success)
                    {


                        Roles.AddUserToRole(model.UserName, model.Role);

 //model.Role is the DropDown Selected Text.. its value is 'Admin'

                        FormsAuthentication.SetAuthCookie(model.UserName,   
   false /* createPersistentCookie */);
                        return RedirectToAction("Index", "EUT");
                    }
                    else
                    {
                        ModelState.AddModelError("",  
     ErrorCodeToString(createStatus));
                    }

                }
                else
                {

                    ModelState.AddModelError("", "User Already exists");
                }
            }

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

在我的Web配置中

 <membership>
      <providers>
        <clear/>
        <add name="AspNetSqlMembershipProvider" type="System.Web.Security.SqlMembershipProvider" connectionStringName="ApplicationServices"
             enablePasswordRetrieval="false" enablePasswordReset="true" requiresQuestionAndAnswer="false" requiresUniqueEmail="false"
             maxInvalidPasswordAttempts="5" minRequiredPasswordLength="6" minRequiredNonalphanumericCharacters="0" passwordAttemptWindow="10"
             applicationName="/" />
      </providers>
    </membership>

    <profile>
      <providers>
        <clear/>
        <add name="AspNetSqlProfileProvider" type="System.Web.Profile.SqlProfileProvider" connectionStringName="ApplicationServices" applicationName="/" />
      </providers>
    </profile>

    <roleManager enabled="true"  defaultProvider="AspNetSqlRoleProvider"
                                    cacheRolesInCookie="true"
                                    cookieName=".myroles"
                                    cookieTimeout="30"
                                    cookieSlidingExpiration="true"
                                    cookieProtection="All">
      <providers>
        <clear/>
        <add name="AspNetSqlRoleProvider" type="System.Web.Security.SqlRoleProvider" connectionStringName="ApplicationServices" applicationName="/" />
        <add name="AspNetWindowsTokenRoleProvider" type="System.Web.Security.WindowsTokenRoleProvider" applicationName="/" />
      </providers>
    </roleManager>

我看过类似的帖子：

Add User Roles on Registration (Forms Authentication) MVC3

Adding users to roles on registring failed ASP.NET MVC3

Adding roles only adding one to user

尝试将所选值与模型属性绑定...仍然无效...

任何建议都会有所帮助

您可以检查角色是否存在，如果不是这样，则添加它：

var adminRoleExists = Roles.RoleExists(AppRoles.Admin.ToString());
if (!adminRoleExists)
{
    Roles.CreateRole(AppRoles.Admin.ToString());
}

角色＆＃39; ＆＃39;没找到
