How to iterate Roles in IEnumerable and display role names in razor view

Am using Identity 2.1.0 with MVC and razor Views. One of my views gets a list of all users with this GET Controller Action:

public async Task<ActionResult> Users() { return View(await UserManager.Users.ToListAsync()); }

Within the View there is a foreach that iterates through each user and displays the usual information like email address, username, etc. I would like to know if there is also a way of iterating through the roles for each user so that I can display the role membership of each user something like this:

Customer Employee

I haven't been able to figure this out. Part of my problem is that I don't have any Intellisense within razor views and haven't been able to find anything helpful on Google.

The View Model is @model IEnumerable<XXXX_My_App.Models.ApplicationUser>. ApplicationUser has a base class of IdentityUser.


The easiest way would be to create a custom ViewModel which contains the user itself and the roles he is member of. An implementation could look like the following:


public async Task<ViewResult> Users() { var users = UserManager.Users; var model = new Collection<UserRoleViewModel>(); foreach (var user in users) { var roles = await UserManager.GetRolesAsync(user.Id); var rolesCollection = new Collection<IdentityRole>(); foreach (var role in roles) { var role = await RoleManager.FindByNameAsync(roleName); rolesCollection.Add(role); } model.Add(new UserRoleViewModel { User = user, Roles = rolesCollection }); } return View("Users", model); }


public class UserRoleViewModel { public ApplicationUser User { get; set; } public Collection<IdentityRole> Roles { get; set; } }

With that you can use the following model in your view to iterate over the appropriate properties

@model ICollection<YourProject.Models.UserRoleViewModel>


If your Usermanager is returning a list of identityusers and so each identityuser should have a roles property which you should be able to enumerate. However this will only be populated if your implementation includes a class which implements IRoleStore but you haven't provided details of your implementation so we can only guess.
