在ASP.NET页，带有 HttpContext 当前，如何获得对当前 RoleProvider 实例?
When inside an ASP.NET page, module or handler with an HttpContext present, how do I get a reference to the current RoleProvider instance?
当调用IPrincipal.IsInRole(..)方法.默认情况下或通过配置，我的提供程序似乎是SqlRoleProvider 实例由我在运行应用程序时给出的错误引起.
It's the provider used for authorization when the IPrincipal.IsInRole(..) method is called. By default, or from configuration, my provider seems to be a SqlRoleProvider instance by an error given when I'm running the app.
我想在运行时检查提供程序的类型，以提供有关实际使用哪个提供程序的反馈.
I want to inspect the type of provider at runtime to provide feedback on which one is actually being used.
推荐答案
静态角色类上具有Provider属性，您可以使用该属性来引用当前的提供程序.
The static Roles class has a Provider property on it which you can use to reference the current provider.
Roles.Provider
，如果您使用的是自定义RoleProvider，则可以对其进行强制转换以访问自定义功能.
and if you are using a custom RoleProvider, you can cast it in order to access custom functionality.
((MyCustomRoleProvider)Roles.Provider).AllYourRoleAreBelongToUs();
