Winform 窗口圆角实现

项目需要，得把Winform的窗口做成圆角，同时把标题栏等一堆东西去掉，做成如下的样子：

首先，在新建Winform之后，在属性栏中，把MaximizeBox和MinimizeBox 置为False，同时将ShowIcon置为False，FormBorderStyle置为None。之后，窗口就变成一块白板了。

然后，PS出一张如上的背景图来，把图做成圆角。将改图设为Winform的背景，BackgroundImageLayout设为Stretch。

网上有人说此后只需要将Winform的BackColor置为Color.Transparent就Ok了，但是VS2010会报错，控件背景不允许使用透明色。

所以只能学习网上有人提到的办法，实现Winform的Paint时间，将窗口重绘成圆角的。

141             list.Add(new Point(2, height - 38));
142             list.Add(new Point(1, height - 42));
143             list.Add(new Point(0, height - 47));
144
145             #endregion
146
147             Point[] points = list.ToArray();
148
149             GraphicsPath shape = new GraphicsPath();
150             shape.AddPolygon(points);
151
152             this.Region = new System.Drawing.Region(shape);
153
154         }

这样就把圆角窗口做出来了。需要说的是，这样设置出来的圆角是又毛刺的，精细程度跟你手动设置的点的个数有关，是个体力活。

借鉴了别人的工作，致敬~
