Checking User Roles to Display

I recently added Identity to my ASP.NET project, but I'm having trouble checking user roles.

I originally create my Admin role in Startup.cs:

private void createRolesandUsers()
{
        ApplicationDbContext context = new ApplicationDbContext();

        var roleManager = new RoleManager<IdentityRole>(new RoleStore<IdentityRole>(context));
        var UserManager = new UserManager<ApplicationUser>(new UserStore<ApplicationUser>(context));

        if (!roleManager.RoleExists("Admin"))
        {

            var role = new Microsoft.AspNet.Identity.EntityFramework.IdentityRole();
            role.Name = "Admin";
            roleManager.Create(role);

            var user = new ApplicationUser();
            user.UserName = "admin";
            user.Email = "[email protected]";

            string userPWD = "********";

            var chkUser = UserManager.Create(user, userPWD);

            if (chkUser.Succeeded)
            {
                var result1 = UserManager.AddToRole(user.Id, "Admin");
            }
        }
}

In my UserController.cs, I have a function to check if the user is an admin:

public Boolean isAdminUser()
{
    if (User.Identity.IsAuthenticated)
    {
        var user = User.Identity;
        ApplicationDbContext context = new ApplicationDbContext();
        var UserManager = new UserManager<ApplicationUser>(new UserStore<ApplicationUser>(context));
        var s = UserManager.GetRoles(user.GetUserId());
        if (s[0].ToString() == "Admin")
        {
            return true;
        }
        else
        {
            return false;
        }
    }
    return false;
}

However, I can't seem to find a way to access the isAdminUser() function from both my Views and my Controllers.

I've done a little bit of research the IsUserInRole() function, but when I tried:

@if (Roles.IsUserInRole(User.Identity.Name, "Admin")) { Html.ActionLink("Edit", "Edit", new { id=item.GuestID }); }

The if statement always returns false.

Try to use HttpContext.Current.User.IsInRole("Admin"); as Roles.IsUserInRole related to old membership provider under System.Web.Security namespace and need roleManager provider configuration in web.config.

@if(HttpContext.Current.User.IsInRole("Admin")) 
{
    Html.ActionLink("Edit", "Edit", new { id = item.GuestID });
}

Another way is to use UserManager

userManager.IsInRole("userId","Admin")
