Here is my code...can someone help? Thanks.

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.DirectoryServices;
using System.DirectoryServices.AccountManagement;


 public static List<string> GetGroups()
    {
        using (PrincipalContext ctx = new PrincipalContext(ContextType.Domain))
        {
            using (p = Principal.FindByIdentity(ctx, "yourUserName")) 
        {
            var groups = p.GetGroups();

            using (groups)
            {
                foreach (Principal group in groups)
                {
                    Console.WriteLine(group.SamAccountName + "-" + group.DisplayName); 
                } 
            }
        }
        } 

    }
