这篇博客介绍了如何在Winform的datagridview中绘制斜线表头。通过自定义绘制事件`PaintLine`，根据给定的参数`type`、`name1`和`name2`，在特定单元格上绘制斜线并显示两个名称。内容包括使用`Graphics`对象进行绘图，设置画笔和刷子颜色，以及定位和绘制文本。

                gp.DrawLine(gridLinePen, new Point(rec.X, rec.Y), new Point(rec.X + rec.Width, rec.Y + rec.Height));

                float x = 55;
                if (type == "1")
                    x = x + 30;
                gp.DrawString(name1, e.CellStyle.Font, Brushes.Black, new PointF(rec.X + 12, rec.Y + 22));
                gp.DrawString(name2, e.CellStyle.Font, Brushes.Black, new PointF(rec.X + x, rec.Y + 5));
            }
