MVC4：UserIsInRole - 无法连接到SQL Server数据库

围绕打破我的头这一点，昨天它工作得很好，今天似乎被打破：MVC4：UserIsInRole - 无法连接到SQL Server数据库

此行生成错误：

@if (Roles.IsUserInRole(HttpContext.Current.User.Identity.Name, "Admin"))

错误是： 无法连接到SQL Server数据库。

整个异常：

的数据库表看上去精致，用户和角色存在，就像之前。

我尝试了以下方法：1.注释掉该行。 2.进入网站并注销。 3.未评论该行。 4.再次登录。 - >这确实解决了这个问题，但是当我再次进入网站时，它弹出。这似乎很奇怪，因为它在2秒钟之前就已经运行了。 – Chen

对于我的使用情况下，添加下面一行在web.config文件中定了！

<add key="enableSimpleMembership" value="false"/>

我发现，使用UserManager.IsInRole(User.Identity.GetUserId(), "Admin")解决了这个问题对我来说。干杯
