asp.net identity get all roles of logged in user

Question

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.

Answer 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();

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();
    }

Don't use @using System.IdentityModel.Claims namespace, Instead of that use

@using System.Security.Claims

    @using System.Security.Claims
    @using Microsoft.AspNet.Identity
    @{      
       var claimsIdentity = User.Identity as System.Security.Claims.ClaimsIdentity;
       var customUserClaim = claimsIdentity != null ? claimsIdentity.Claims.FirstOrDefault(x => x.Type == "cutomType") : null;
       var customTypeValue= customUserClaim != null ? customUserClaim .Value : User.Identity.GetUserName();
       var roleOfUser = claimsIdentity != null ? claimsIdentity.Claims.FirstOrDefault(x => x.Type == ClaimTypes.Role).Value :"User";

}

After getting Identity User from SignIn Manager, callGetRolesAsync on UserManager and pass identity user as parameter. It will return of List of roles, identity user enrolled in

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