Store Active Directory Querry into a Multidimensional array

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);
                }
            }
        }
    }
}

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

Thanks,
