我正在使用许可的 Devart dotConnect 产品连接到我的 ASP.NET MVC5 项目中的 PostgreSql 数据库。我对 Devart Rolemanager 有疑问。我按照本教程安装了 Dotconnect PostgreSql https://www.devart.com/dotconnect/postgresql/articles/aspproviders.html#role

一切正常，但是当我在 View 中调用管理员角色时，此功能无法正常工作。

在 DB 表 (aspnet_users) 我有一个用户 (Foo)，在表 (aspnet_roles) 管理员角色中，在表 (aspnet_usersinroles) 中与 Id 连接。
功能：

@if(User.IsInRole("admin"))
{
<p>Test Admin page!</p>
}

快速手表显示：错误。

这是我的 web.config 的一部分：

不确定这是查询中的拼写错误还是您的视图有问题，但被剪断的代码（非常缩写）似乎包含错误。你那里似乎没有 if 语句。

@User.IsInRole("admin") { }

应该

@if (User.IsInRole("admin")) { }
