.CS fil der skal hente fra anden .CS fil

Jeg er nok lidt at en newbie i C# (startede idag *s*), så jeg har lige et lille spørgsmål...

Jeg har følgende kode fordelt på 3 filer....

//Filen hedder ForumThreadData.cs
using System;
using System.Configuration;

using System.Web;
using System.Web.UI;
using System.Web.UI.HtmlControls;
using System.Web.UI.WebControls; 

public class ForumThreadData: Page
{
    private int intForumThreadID;
    private int intForumID;
    private int intOriginalThreadID;
    private string stringTitle;
    private string stringBody;
    private DateTime dateCreatedDate;
    private bool boolIsOriginalThread;
    private bool boolApproved;
   
    public int forumThreadID
    {
        get { return intForumThreadID; }
        set { intForumThreadID = value; }
    }
   
    public int forumID
    {
        get { return intForumID; }
        set { intForumID = value; }
    }
   
    public int originalThreadID
    {
        get { return intOriginalThreadID; }
        set { intOriginalThreadID = value; }
    }
   
    public string title
    {
        get { return stringTitle; }
        set { stringTitle = value; }
    }
   
    public string body
    {
        get { return stringBody; }
        set { stringBody = value; }
    }
   
    public DateTime createdDate
    {
        get { return dateCreatedDate; }
        set { dateCreatedDate = value; }
    }
   
    public bool isOriginalThread
    {
        get { return boolIsOriginalThread; }
        set { boolIsOriginalThread = value; }
    }
   
    public bool approved
    {
        get { return boolApproved; }
        set { boolApproved = value; }
    }
}


/*
Filen hedder ForumData.cs, ideen er at denne container class skal have en instanser af den forrige klasse
*/
using System;
using System.Configuration;

using System.Web;
using System.Web.UI;
using System.Web.UI.HtmlControls;
using System.Web.UI.WebControls; 

public class ForumData: Page
{
    private int intForumID;
    private int intImageID;
    private int intPortalID;
    private int[] arrayCategoryID;
    private string stringTitle;
    private string stringDescription;
    private bool boolApproved;
    private forumThreadData[] forumThreads;
   
    public int forumID
    {
        get { return intForumID; }
        set { intForumID = value; }
    }

    public int imageID
    {
        get { return intImageID; }
        set { intImageID = value; }
    }

    public int[] categoryID
    {
        get { return arrayCategoryID; }
        set { arrayCategoryID = value; }
    }
   
    public int portalID
    {
        get { return intPortalID; }
        set { intPortalID = value; }
    }
   
    public string title
    {
        get { return stringTitle; }
        set { stringTitle = value; }
    }
   
    public string description
    {
        get { return stringDescription; }
        set { stringDescription = value; }
    }
   
    public bool approved
    {
        get { return boolApproved; }
        set { boolApproved = value; }
    }
}


<!--- Denne fil hedder ForumData.aspx og skal blot teste eksemplet --->
<%@ Page Language="C#" Inherits="ForumData" Src="ForumData.cs" Description="MainPage" %>

<script language="C#" runat="server">
void Page_Load(Object Source, EventArgs E)
{
    ForumData fd = new ForumData();
   
    //Create category array for test
    int[] arrayCategory = {1,2,5,8,3,7};
   
    //Insert test
    fd.forumID = 1;
    fd.imageID = 1;
    fd.portalID = 1;
    fd.title = "Børnetøj - Piger";
    fd.categoryID = arrayCategory;   
    fd.description = "Skal børnetøj til piger altid være i pigefarver?";
    fd.approved = true;
   
    //Instanciate message variable   
    string message = "";
   
    message += "ForumID: " + fd.forumID + "<br>";
    message += "ImageID: " + fd.imageID + "<br>";
    message += "PortalID: " + fd.portalID + "<br>";
    message += "Title: " + fd.title + "<br>";
    message += "Category 1: " + fd.categoryID[0] + "<br>";
    message += "Description: " + fd.description + "<br>";
    msg.Text = message;
   
}
</script>
<asp:label id="msg" runat="server"></asp:label>


Kort sagt har jeg problemer med at få min ForumData.cs fil til at fange en ForumThreadData classen....
