winform重绘窗体成圆角（网上借鉴）
winform做圆角窗体：
1 //重绘窗体为圆角 2 private void frmMain_Paint(object sender, PaintEventArgs e) 3 { 4 #region 5 6 List<Point> list = new List<Point>(); 7 int width = this.Width; 8 int height = this.Height; 9 10 #region 四个圆角 11 12 //左上 13 list.Add(new Point(0, 5)); 14 list.Add(new Point(1, 5)); 15 list.Add(new Point(1, 3)); 16 list.Add(new Point(2, 3)); 17 list.Add(new Point(2, 2)); 18 list.Add(new Point(3, 2)); 19 list.Add(new Point(3, 1)); 20 list.Add(new Point(5, 1)); 21 list.Add(new Point(5, 0)); 22 23 //右上 24 list.Add(new Point(width - 5, 0)); 25 list.Add(new Point(width - 5, 1)); 26 list.Add(new Point(width - 3, 1)); 27 list.Add(new Point(width - 3, 2)); 28 list.Add(new Point(width - 2, 2)); 29 list.Add(new Point(width - 2, 3)); 30 list.Add(new Point(width - 1, 3)); 31 list.Add(new Point(width - 1, 5)); 32 list.Add(new Point(width - 0, 5)); 33 34 //右下 35 list.Add(new Point(width - 0, height - 5)); 36 list.Add(new Point(width - 1, height - 5)); 37 list.Add(new Point(width - 1, height - 3)); 38 list.Add(new Point(width - 2, height - 3)); 39 list.Add(new Point(width - 2, height - 2)); 40 list.Add(new Point(width - 3, height - 2)); 41 list.Add(new Point(width - 3, height - 1)); 42 list.Add(new Point(width - 5, height - 1)); 43 list.Add(new Point(width - 5, height - 0)); 44 45 //左下 46 list.Add(new Point(5, height - 0)); 47 list.Add(new Point(5, height - 1)); 48 list.Add(new Point(3, height - 1)); 49 list.Add(new Point(3, height - 2)); 50 list.Add(new Point(2, height - 2)); 51 list.Add(new Point(2, height - 3)); 52 list.Add(new Point(1, height - 3)); 53 list.Add(new Point(1, height - 5)); 54 list.Add(new Point(0, height - 5)); 55 #endregion 56 57 Point[] points = list.ToArray(); 58 59 GraphicsPath shape = new GraphicsPath(); 60 61 shape.AddPolygon(points); 62 63 this.Region = new System.Drawing.Region(shape); 64 #endregion 65 }
