先贴代码        private void listBox2_DrawItem(object sender, DrawItemEventArgs e)
        {
            Brush b;
            string str = listBox2.Items[e.Index].ToString();
            int z = str.IndexOf(" ");
            string sj = str.Substring(z);
            if (gettime(sj)==true)//方法,判断用哪种颜色
            {
                b = new SolidBrush(Color.Black);
            } 
            else
            {
                b = new SolidBrush(Color.Red);
            }
            e.Graphics.DrawString(str, this.Font, b, e.Bounds);
        }虽然我实现了我希望突出显示的项的颜色,但是这个列表框却不能选中了,点点没反映求高手帮忙解答
