        e = new DrawItemEventArgs(e.Graphics, 
                                  e.Font, 
                                  e.Bounds, 
                                  e.Index,
                                  e.State ^ DrawItemState.Selected,

                                  Color.Yellow);//Choose the color

    // Draw the background of the ListBox control for each item.
    e.DrawBackground();
    // Draw the current item text
    e.Graphics.DrawString(listBox1.Items[e.Index].ToString(),e.Font, Brushes.Black, e.Bounds, StringFormat.GenericDefault);
    // If the ListBox has focus, draw a focus rectangle around the selected item.
    e.DrawFocusRectangle();
