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();
