Hi, I am creating an addressbook where you can add First Name, Last Name, Address, City, State and Zip into textboxes and have them display in a listbox on the add button click event. Now I need to be able to remove the selected Item from the listbox and from the Array they are stored in. The whole program works good and I have it so that the selected item is removed from the Array I just can not get the entry to remove from the listbox display. I have tried a while statement and a for statement with no luck. Any help would be great. Thanks.
I commented out the two statements that did not work for me. The For errors saying the index is going to -1, and the while tells me that there is an unhandled null reference.

private void btnDelete_Click(object sender, EventArgs e)
        {
            //select record for deletion, deletes from array
            adrary[SelectedIndex] = null;

            for (int i = SelectedIndex; i < index; i++)
            {
                adrary[i] = adrary[i + 1];
            }
            index--;


            //while (lstOutput.SelectedItems.Count > 0)
            //{
            //    lstOutput.Items.Remove(lstOutput.SelectedItems[0]);
            //}
            //index--;

            //ListBox.SelectedObjectCollection Obj = new ListBox.SelectedObjectCollection(lstOutput);
            //for (int i = Obj.Count - 1; i >= 0; i--)
            //{
            //    lstOutput.Items.Remove(Obj[i]);
            //} 
        }
