Microsoft.AspNetCore.Mvc namespace provides public property User of ClaimsPrincipal type which hold the information of current logged in user , to get current role id ClaimsPrincipal class have static method FindFirstValue you can use that e.g. string User.FindFirstValue(ClaimTypes.Role);

In Identity you could use UserManager to access each users roles as well. Since roles already have been implemented therefor you don't need any extra configuration. So consider this example:

public ActionResult MyAction()
{
    userManager = HttpContext.GetOwinContext().GetUserManager<ApplicationUserManager>();

    // return a list of current user's roleIDs
    var roles = userManager.FindById(User.Identity.GetUserId()).Roles.Select(r => r.RoleId);
}

You can get the roles the member has like this:

using System.Web.Security;    
string[] roles = Roles.GetRolesForUser(User.Identity.Name);

A user can have multiple roles so the type of return value is string[].

UPDATED
In ASP.NET Identity 2.0, you can enable RoleManager as the following example:

Models/IdentityModels.cs

public class ApplicationRole : IdentityRole
{
}

App_Start/IdentityConfig.cs

public class ApplicationRoleManager : RoleManager<ApplicationRole, string>
{
    public ApplicationRoleManager(IRoleStore<ApplicationRole, string> store)
        : base(store)
    {
    }
    public static ApplicationRoleManager Create(IdentityFactoryOptions<ApplicationRoleManager> options, IOwinContext context)
    {
        var dbContext = context.Get<ApplicationDbContext>();
        var roleStore = new RoleStore<ApplicationRole>(dbContext);
        var manager = new ApplicationRoleManager(roleStore);

        // Add some roles (e.g. "Administrator") if needed
        if (!manager.Roles.Any(r => r.Name == "Administrator"))
        {
            manager.Create(new ApplicationRole
            {
                Name = "Administrator"
            });
        }
        return manager;
    }
}

App_Start/Startup.Auth.cs

public partial class Startup
{
    public void ConfigureAuth(IAppBuilder app)
    {
        app.CreatePerOwinContext(ApplicationDbContext.Create);
        app.CreatePerOwinContext<ApplicationUserManager≥(ApplicationUserManager.Create);

        // Add this line
        app.CreatePerOwinContext<ApplicationRoleManager>(ApplicationRoleManager.Create);
    }
}

Controllers/AccountController.cs

public class AccountController : Controller
{
    private ApplicationUserManager _userManager; 
    private ApplicationRoleManager _roleManager;

    public AccountController()
    {
    }

    public AccountController(ApplicationUserManager userManager, ApplicationRoleManager roleManager, ApplicationSignInManager signInManager)
    {
        UserManager = userManager;
        RoleManager = roleManager;
        SignInManager = signInManager;
    }

    public ApplicationRoleManager RoleManager
    {
        get
        {
            return _roleManager ?? HttpContext.GetOwinContext().Get<ApplicationRoleManager>();
        }
        private set
        {
            _roleManager = value;
        }
    }
}

Then, you can get roles from UserId in Account controller.

var roles = UserManager.GetRoles(User.Identity.GetUserId());
