Essentially I want to query 2 domain controllers in AD and compare the information between the two.  I only need to be able to store the HostName and Last Login time stamp from each Domain Controller.  I would like to modify the code to return the array to the calling function.  

I----------------------------------------------------------------------------------------------------------------------
       private void Button_1_Click(object sender, EventArgs e)
        {
                string OUDN = txtTargetList_Path.Text;
                try
                {
                    DirectoryEntry entry = new DirectoryEntry("LDAP://" + OUDN);
                    DirectorySearcher DirSearch = new DirectorySearcher(entry);
                    DirSearch.Filter = "(objectClass=computer)";
                    DirSearch.PageSize = 100000;

                    foreach(SearchResult results in DirSearch.FindAll())
                    {
                        string Line = "";
                        string HName = "";
                        string LstLgn = "";
                       
                        foreach(string Value in results.Properties.PropertyNames)
                        {
                            if(results.Properties[Value]!=null)
                            {
                                if (Value == "name")
                                {
                                    HName = (string)results.Properties[Value][0];
                                }
                                if(Value == "lastlogon")
                                {
                                    long lastLogon = (long)results.Properties[Value][0];
                                    LstLgn = DateTime.FromFileTime(lastLogon).ToString();
                                }
                            }
                        }
                        Line = HName + "," + LstLgn;
                        listBox1.Items.Add(Line);
                    }
                }
                catch (IOException Iox)
                {
                    lstErrorLog.Items.Add(Iox.Data.ToString());
                }
                catch (DirectoryServicesCOMException ex)
                {
                    lstErrorLog.Items.Add(ex.Message.ToString());
                }
        }

The code below shows how to build and return an ArrayList from a function.
using System;

using System.Collections;
 

namespace clrtest

{

    // Data will represent one element in the array

    class Data

    {

        public Data(string name_, string lastlogin_)

        {

            m_name = name_;

            m_lastlogin = lastlogin_;

        }
 

        // Accessor for name

        public string Name

        {

            get

            {

                return m_name;

            }

        }
 

        // Accessor for lastlogin

        public string LastLogin

        {

            get

            {

                return m_lastlogin;

            }

        }
 

        private string m_name;

        private string m_lastlogin;

    }
 

    class Program

    {

        // Dummy function just to demonstrate how to return array

        static ArrayList foo()

        {

            // Build a dummy array

            ArrayList al = new ArrayList();

            al.Add(new Data("John Doe", "18/11/2007"));

            al.Add(new Data("Jane Smith", "18/11/2007"));
 

            // Return array

            return al;

        }
 

        static void Main(string[] args)

        {

            // foo() will return an ArrayList object

            ArrayList al = foo();
 

            // Iterate through items in ArrayList

            foreach (Object obj in al)

            {

                // Cast boxed object to Data element

                Data data = obj as Data;
 

                // IF cast was successful output the data as proof

                if (data != null)

                {

                    Console.WriteLine(data.Name);

                    Console.WriteLine(data.LastLogin);

                }

            }

        }

    }

}

So you'd need to change your function to something like this...
private ArrayList Button_1_Click(object sender, EventArgs e)

{

        //////////////////////////////////////////////////////////////////////

        // Create new array

        ArrayList al = new ArrayList();

        //////////////////////////////////////////////////////////////////////
 

        string OUDN = txtTargetList_Path.Text;

        try

        {

            DirectoryEntry entry = new DirectoryEntry("LDAP://" + OUDN);

            DirectorySearcher DirSearch = new DirectorySearcher(entry);

            DirSearch.Filter = "(objectClass=computer)";

            DirSearch.PageSize = 100000;
 

            foreach(SearchResult results in DirSearch.FindAll())

            {

                string Line = "";

                string HName = "";

                string LstLgn = "";

                

                foreach(string Value in results.Properties.PropertyNames)

                {

                    if(results.Properties[Value]!=null)

                    {

                        if (Value == "name")

                        {

                            HName = (string)results.Properties[Value][0];

                        }

                        if(Value == "lastlogon")

                        {

                            long lastLogon = (long)results.Properties[Value][0];

                            LstLgn = DateTime.FromFileTime(lastLogon).ToString(); 

                        }

                    }

                }

                Line = HName + "," + LstLgn;

                listBox1.Items.Add(Line);
 

                //////////////////////////////////////////////////////////////

                // Add name/logintime to array

                al.Add(new Data(HName, LstLgn));

                //////////////////////////////////////////////////////////////

            }

        }

        catch (IOException Iox)

        {

            lstErrorLog.Items.Add(Iox.Data.ToString());

        }

        catch (DirectoryServicesCOMException ex)

        {

            lstErrorLog.Items.Add(ex.Message.ToString());

        }
 

        //////////////////////////////////////////////////////////////////////

        // Return array

        return al;

        //////////////////////////////////////////////////////////////////////

al.Add(new Data(HName, LstLgn));

Returns 3 errors when I compile it?  I think that I am missing a Library.  Can you please help with this too?

Error      1      The type or namespace name 'data' could not be found (are you missing a using directive or an assembly reference?)      C:\Documents and Settings\tcbea\Desktop\VS Projects Nathan\SITS-SQT\SITS-SQT\SQT.cs      4433      32      SITS-SQT
