it is no necessary to copy list from form to from then you can declare a class and within that class you declare a static ListBox object then you can use it in both forms I mean public class myList { static public ListBox TheList = new ListBox(); } in the form1 and form2 you can get the same List myList.TheList you can

Why a form2 to do this? You can do it from form1 without displaying to the user. Simply declare and don't add to controls. Just place ListBox MyHiddenListBox = new ListBox(); Before public Form1() and use it.

isnt there any other way because this seems a bit complicated all i want to do is copy one listbox from form2 to form1's listbox and the listbox will have results which i do not know about so i can just put items.add (somthing); because i dont know what will be in the listbox.

you can create your own clonable listbox public class myListBox : ListBox ICloneable { #region ICloneable Members public object Clone() { return this.MemberwiseClone(); } #endregion } Here how to use it myListBox x = new myListBox(); x.Items.Add(a); x.Items.Add(b); x.Items.Add(c); myListBox y = x.Clone() as myListBox; for (int i = 0; i { MessageBox.Show(y.Items[i].ToString()); }
