asp.net identity get all roles of logged in user

I created a role based menu for which I followed this tutorial. Some where down that page you'll see this line of code:

String[] roles = Roles.GetRolesForUser();

It returns all roles of the currently logged in user. I was wondering how to accomplish this with the new ASP.NET Identity system?

It's still pretty new and there is not much to find about it.

Solution 1:

Controller.User.Identity is a ClaimsIdentity. You can get a list of roles by inspecting the claims...

var roles = ((ClaimsIdentity)User.Identity).Claims
                .Where(c => c.Type == ClaimTypes.Role)
                .Select(c => c.Value);

--- update ---

Breaking it down a bit more...

using System.Security.Claims;

// ........

var userIdentity = (ClaimsIdentity)User.Identity;
var claims = userIdentity.Claims;
var roleClaimType = userIdentity.RoleClaimType;
var roles = claims.Where(c => c.Type == ClaimTypes.Role).ToList();

// or...
var roles = claims.Where(c => c.Type == roleClaimType).ToList();

Solution 2:

Here's an extension method of the above solution.

    public static List<string> Roles(this ClaimsIdentity identity)
    {
        return identity.Claims
                       .Where(c => c.Type == ClaimTypes.Role)
                       .Select(c => c.Value)
                       .ToList();
    }

Solution 3:

After getting the Identity User from SignInManager, call GetRolesAsync on UserManager and pass identity user as parameter.

It will return a list of roles the identity user has enrolled in.

var rolesList = await userManager.GetRolesAsync(identityuser).ConfigureAwait(false);
