Object reference not set to an instance of an object.

Hej, jeg har siddet super l�nge og bakset med dette kodev�rk, der bare ikke vil virke.

M�let er at lave et forum, koden giver fin mening i sig selv, men min "ForumEntry" vil ikke populate min "Entries", der ellers er en "IList<ForumEntry>"

Thread.aspx.cs

CSharp kode

 namespace Forum
 {
     public partial class Thread : System.Web.UI.Page
     {
         private Int32 ThreadIdentifier;
         private IList<ThreadEntry> Entries;
         protected void Page_Load(object sender, EventArgs e)
         {
             this.ThreadIdentifier = Convert.ToInt32(Request.QueryString["ID"]);
 
             populateThread();
             showthreads();
         }
 
         public void populateThread()
         {
             ThreadEntry entry = new ThreadEntry(this.ThreadIdentifier);
             entry.ThreadName = "abe";
             entry.EntryID = 1;
             entry.UserID = 1;
             entry.NickName = "T1MeW4sTeR";
             entry.Text = "Dette er det først indlæg i en ellers lang tråd. :)";
             entry.datetime = "hh";
 
             this.Entries.Add(entry);
         }
 
         public void showthreads()
         {
             foreach(ThreadEntry entry in this.Entries)
             {
                 DivEntries.InnerHtml += "Nickname: " + entry.NickName.ToString();
                 DivEntries.InnerHtml += " Time: " + entry.datetime.ToString();
                 DivEntries.InnerHtml += "<br /><br />" + entry.Text.ToString();
             }
         }
     }
 }

Thread.cs

CSharp kode

 namespace Forum
 {
     public abstract class ForumThread
     {
         public Int32 ThreadID;
         public string ThreadName;
     }
 }

ThreadEntry.cs

CSharp kode

 namespace Forum
 {
     public class ThreadEntry : ForumThread
     {
         public Int32 EntryID;
         public Int32 UserID;
         public string NickName;
         public string datetime;
         public string Text;
 
         public ThreadEntry(Int32 id)
         {
             this.ThreadID = id;
         }
     }
 }

Er der ikke en, der kan hooke mig up med en l�kker l�sning?
