{

}

However How can I check if my user is

Answer 1

Please, use this simple way :

@using Microsoft.AspNet.Identity

@if (Request.IsAuthenticated)
{
    if (User.IsInRole("Administrator") || User.IsInRole("Moderator"))
    {
        ... Your code here
    }
}

Answer 2

I wanted to elaborate a little on mattytommo's answer, here is what I use:

Extension Method:

public static bool IsInAnyRole(this IPrincipal user, string[] roles)
        {
            //Check if authenticated first (optional)
            if (!user.Identity.IsAuthenticated) return false;
            var userRoles = Roles.GetRolesForUser(user.Identity.Name);
            return userRoles.Any(roles.Contains);
        }

Constants:

public static class Role
{
    public const string Administrator = "Administrator";
    public const string Moderator = "Moderator";
}

Usage:

if (User.IsInAnyRole(new [] {Role.Administrator,Role.Moderator}))
{
    //Do stuff
}
