Question

Hello; I am  junior developer and pretty new to C# was wondering if someone could take look at my code and tell me why I get a "Object reference not set to an instance of an object" error message. my code is posted below... thanks in advance for any type of help.

using System;

using System.DirectoryServices;

 

using System.Linq;

namespace AuctionDash

{ 

public partial class ActiveDirectory : System.Web.UI.Page

    {

protected void Page_Load(object sender, EventArgs e)

        {                        

DirectoryEntry activeDirectory = new DirectoryEntry("LDAP://dc-1.domain.local",null,null)

activeDirectory.Path =

LDAP://dc-1.zachys.local/CN=aduc,CN=Users,DC=domian,DC=local;

           

DirectorySearcher adSearcher = new DirectorySearcher();

adSearcher.PropertiesToLoad.Add("name")

adSearcher.PropertiesToLoad.Add("Description");

adSearcher.Filter = (

"(&(&(objectClass=person)(objectcatagory=Group))(objectclass=Members))");         

 

adSearcher.SearchScope = SearchScope=.Base: 

      

SearchResultCollection results = adSearcher.FindAll();

         

if ((results != null) && (results.PropertiesLoaded.Contains("name" + "Description")))

  results.PropertiesLoaded.ToString();

           

foreach (SearchResult result in results)

            {
               {

                   adSearcher.PropertiesToLoad.Add("name").ToString

                   adSearcher.PropertiesToLoad.Add("Description").ToString;

                }

            lblStatus.Text = adSearcher.SearchRoot.ToString();

                adSearcher.Dispose();

            }

            }

        }

}
