OutOfRange Exception from ArrayList

Question

I have a ListBox and set its Datasource to an ArrayList, If I remove the last item in the ArrayList and then click on the ListBox I get an outOfRange Exception. I have copied the code which removes the item from the ArralList and error below. Any help would be greatly appreciated: Code ------ private void butRemove_Click(object sender, System.EventArgs e) { //g_InterestedPartiesArray is the ArrayList this.bChangesMade=true; BLUser blUser = new BLUser(); int nLoop=0; foreach (BLUser row in this.g_InterestedPartiesArray) { blUser=row as BLUser; if (blUser.Pid==System.Convert.ToInt32(this.lbInterestedPeople.SelectedValue)) { this.g_InterestedPartiesArray.RemoveAt(nLoop); break; } nLoop++; } //Refresh the listbox with the changed data in the ArrayList this.lbInterestedPeople.DataSource=null; this.lbInterestedPeople.DataSource=this.g_InterestedPartiesArray; this.lbInterestedPeople.DisplayMember="FullName"; this.lbInterestedPeople.ValueMember="Pid"; } Error ------ Error : Index was out of range. Must be non-negative and less than the size of the collection.
