1. 把需要用的图片存入imageList控件中。

2. 设置listview的OwnerDraw属性：true。

3. 在listview的DrawColumnHeader事件中写如下代码

view plaincopy to clipboardprint?
private void listView1_DrawColumnHeader(object sender, DrawListViewColumnHeaderEventArgs e)
        {
            e.DrawDefault = true;   // 由操作系统绘制此标题。
        }
private void listView1_DrawColumnHeader(object sender, DrawListViewColumnHeaderEventArgs e)
        {
            e.DrawDefault = true;   // 由操作系统绘制此标题。
        }

4. 在listview的DrawSubItem事件中绘制图片

view plaincopy to clipboardprint?
private void listView1_DrawSubItem(object sender, DrawListViewSubItemEventArgs e)
        {
Image tmp_image = this.imageList1.Images[0]; //声明Image实例，用来指定后面要画的那个图标
            Rectangle rect = new Rectangle(); //指明画的矩形对象
            if (e.ColumnIndex == 1) //在第几列画
            {
                switch (e.SubItem.Text)
                {
                    case "2":
                        tmp_image = this.imageList1.Images[0];
                        break;
                }
                rect.X = e.Bounds.X;
                rect.Y += e.Bounds.Y;
                rect.Width = tmp_image.Width;
                rect.Height = e.Bounds.Height;
                e.Graphics.DrawImage(tmp_image, rect);
            }
            else if (e.ColumnIndex == 2)
            {
                switch (e.SubItem.Text)
                {
                    case "3":
                        tmp_image = this.imageList1.Images[1];
                        break;
                }
                rect.X = e.Bounds.X;
                rect.Y += e.Bounds.Y;
                rect.Width = tmp_image.Width;
                rect.Height = e.Bounds.Height;
                e.Graphics.DrawImage(tmp_image, rect);
            }
            else if (e.ColumnIndex == 3)
            {
                switch (e.SubItem.Text)
                {
                    case "4":
                        tmp_image = this.imageList1.Images[2];
                        break;
                }
                rect.X = e.Bounds.X;
                rect.Y += e.Bounds.Y;
                rect.Width = tmp_image.Width;
                rect.Height = e.Bounds.Height;
                e.Graphics.DrawImage(tmp_image, rect);
            }
            else if (e.ColumnIndex == 4)
            {
                switch (e.SubItem.Text)
                {
                    case "1":
                        tmp_image = this.imageList1.Images[0];
                        break;
                    case "2":
                        tmp_image = this.imageList1.Images[1];
                        break;
                    case "5":
                        tmp_image = this.imageList1.Images[2];
                        break;
                    case "不等于":
                        tmp_image = this.imageList1.Images[3];
                        break;
                }
                rect.X = e.Bounds.X;
                rect.Y += e.Bounds.Y;
                rect.Width = tmp_image.Width;
                rect.Height = e.Bounds.Height;
                e.Graphics.DrawImage(tmp_image, rect);
            }
            else
            {
                e.DrawDefault = true;
            }
        }
