ASP.NET MVC 3: How to get User's Role in a Controller Method?

问题

I want to be able to

1. Get a list of roles of the current authenticated user.
2. Filter the data provided to that user based on their role.

I see ways to check if the user is in a particular role, but I don't care what role they participate. The database will know what roles are allowed to see what data. I need to submit a collection of these roles to the data service to filter the data based on those roles.

So first step is how do I get all roles associated with the current user in a controller method?

EDIT:

This seemed to work out nicely:

Roles.GetRolesForUser(User.Identity.Name)

Supporting answers still welcome.

回答1:

Roles.GetRolesForUser(User.Identity.Name)

回答2:

This can be done with a single statement:

User.IsInRole("admin");

回答3:

If anyone need this information, in case your user has many roles but you're looking for one, you could do this:(i thought id share)

@if (Request.IsAuthenticated)
{
   string[] roles = Roles.GetRolesForUser();
   foreach (string role in roles)
   {
       if (role.Contains("admin"))
       {
           <li>@Html.ActionLink("Administration", "Admin", "Movies")</li>
           break;
       }
   }
}
