C#中用listview显示列表

        //干部人事档案目录列表

            listView1.SmallImageList = imgList;
            this.listView1.Columns.Add(ch);    //将列头添加到ListView控件。
            this.listView1.BeginUpdate();   //数据更新，UI暂时挂起，直到EndUpdate绘制控件，可以有效避免闪烁并大大提高加载速度

            this.listView1.EndUpdate();  //结束数据处理，UI界面一次性绘制。
