绘制圆角矩形：

1. public static void DrawRoundRectangle(Graphics g, Pen pen, Rectangle rect, int cornerRadius)
   
2. {
   
3.     using (GraphicsPath path = CreateRoundedRectanglePath(rect, cornerRadius))
   
4.     {
   
5.         g.DrawPath(pen, path);
   
6.     }
   
7. }
   
8. public static void FillRoundRectangle(Graphics g, Brush brush, Rectangle rect, int cornerRadius)
   
9. {
   
10.     using (GraphicsPath path = CreateRoundedRectanglePath(rect, cornerRadius))
    
11.     {
    
12.         g.FillPath(brush, path);
    
13.     }
    
14. }
    
15. internal static GraphicsPath CreateRoundedRectanglePath(Rectangle rect, int cornerRadius)
    
16. {
    
17.     GraphicsPath roundedRect = new GraphicsPath();
    
18.     roundedRect.AddArc(rect.X, rect.Y, cornerRadius * 2, cornerRadius * 2, 180, 90);
    
19.     roundedRect.AddLine(rect.X + cornerRadius, rect.Y, rect.Right - cornerRadius * 2, rect.Y);
    
20.     roundedRect.AddArc(rect.X + rect.Width - cornerRadius * 2, rect.Y, cornerRadius * 2, cornerRadius * 2, 270, 90);
    
21.     roundedRect.AddLine(rect.Right, rect.Y + cornerRadius * 2, rect.Right, rect.Y + rect.Height - cornerRadius * 2);
    
22.     roundedRect.AddArc(rect.X + rect.Width - cornerRadius * 2, rect.Y + rect.Height - cornerRadius * 2, cornerRadius * 2, cornerRadius * 2, 0, 90);
    
23.     roundedRect.AddLine(rect.Right - cornerRadius * 2, rect.Bottom, rect.X + cornerRadius * 2, rect.Bottom);
    
24.     roundedRect.AddArc(rect.X, rect.Bottom - cornerRadius * 2, cornerRadius * 2, cornerRadius * 2, 90, 90);
    
25.     roundedRect.AddLine(rect.X, rect.Bottom - cornerRadius * 2, rect.X, rect.Y + cornerRadius * 2);
    
26.     roundedRect.CloseFigure();
    
27.     return roundedRect;
    
28. }
