How to Get a User Roles in ASP.NET Identity

In this article, I am going to discuss How to Get User Roles in ASP.NET Identity with Examples. Kindly take a look at our previous article, where we discussed How to Assign a User to a Role in ASP.NET Identity.

How to Get a User Roles in ASP.NET Identity

In order to get a user role in ASP.NET Identity, we need to use the GetRoles or GetRolesAsync method. The GetRoles or GetRolesAsync method returns all roles for a given user and returns the result of the operation as an IList<string> object as follows.

IList<string> userRoles = UserManager.GetRoles(userId);
IList<string> userRoles = await UserManager.GetRolesAsync(userId);

The GetRoles method is called by the UserManager, which is responsible for performing the user-related operations in ASP.NET Identity.

UserManager In ASP.NET Identity:

In ASP.NET Identity, we need to use the GetUserManager method to get the ApplicationUserManager from the Owin context as follows.

ApplicationUserManager UserManager = HttpContext.GetOwinContext().GetUserManager<ApplicationUserManager>();

Example to Get a User Roles in ASP.NET Identity:

So, you can use the following method in ASP.NET MVC Application to get a User Roles using ASP.NET Identity. In the below code, we have declared a method that takes the id of the user we want to get its roles. We pass this id to the GetRoles method that returns all of its roles as a collection of role names. We then return this result set.

private IList<string> GetUserRoles(string userId)
{
    ApplicationUserManager UserManager = HttpContext.GetOwinContext().GetUserManager<ApplicationUserManager>();
    var roles = UserManager.GetRoles(userId);

    return roles;
}

Namespaces:

In order to use the GetUserManager method and the GetRoles method, we have to include the following two namespaces:
using Microsoft.AspNet.Identity;
using Microsoft.AspNet.Identity.Owin;
