Get ASP.NET Identity users by role

I created a new MVC project with ASP.NET Identity as my authentication and authorization framework, using the individual authentication method. I successfully added 3 roles to the application: Admin, Customer, Owner.

Now I've made three action methods in my HomeController: "All Admins", "All Customers", "All Owners". How can I, in each action method, display the users that are in each role and their total count? Meaning when I click on "All Admins" it display all users with admin roles, and the same with the "All Customers" and "All Owners" actions.

I could not find the SingleAsync method of the RoleManager as described by CodeCaster.

So there is another way to get the role by name:

        string roleName = "Employee";

        var role = await RoleManager.FindByNameAsync(roleName);

and then get the users:

    var users  = UserManager.Users.Where(x=>x.Roles.Any(y=>y.RoleId==role.Id))
                    .Select(x => new {UserId = x.Id,FullName = x.FullName });

I had similar problem so I used something like this:

var administrators = from role in _roleManager.Roles
    from userRoles in role.Users
    join user in _userManager.Users on userRoles.UserId equals user.Id
    where role.Name == "Administrator"
    select new UserVm()
    {
        Id = user.Id,
        FirstName = user.FirstName,
        LastName = user.LastName,
        Email = user.Email,
        Role = role.Name
    };

You can use the RoleManager and UserManager. The latter lets you query on RoleId only, so you'll have to look up the Role first:

// Look up the role
string roleName = "Admin";
var role = await _roleManager.Roles.SingleAsync(r => r.Name == roleName);

// Find the users in that role
var roleUsers = _userManager.Users.Where(u => u.Roles.Any(r => r.RoleId == role.Id));

Now you can send the roleUsers to a view that displays the users and their total count.
