private void Form1_Paint(object sender, PaintEventArgs e)         { 　　　　　// (实心刷)                   Rectangle  myrect1 = new Rectangle(20, 80, 250, 100);                  SolidBrush  mysbrush1 = new SolidBrush(Color.DarkOrchid);                                   SolidBrush  mysbrush2 = new SolidBrush(Color.Aquamarine);                         SolidBrush  mysbrush3 = new SolidBrush(Color.DarkOrange); 　　　　　//(梯度刷)                   LinearGradientBrush  mylbrush5 = new LinearGradientBrush(rect1,                   Color.DarkOrange, Color.Aquamarine,                   LinearGradientMode.BackwardDiagonal);                  //(阴影刷)                  HatchBrush  myhbrush5 = new HatchBrush(HatchStyle.DiagonalCross,                   Color.DarkOrange, Color.Aquamarine);                   HatchBrush  myhbrush2 = new HatchBrush(HatchStyle.DarkVertical,                   Color.DarkOrange, Color.Aquamarine);                   HatchBrush  myhbrush3 = new HatchBrush(HatchStyle.LargeConfetti,                   Color.DarkOrange, Color.Aquamarine);                  //(纹理刷)                   TextureBrush textureBrush = new TextureBrush(new Bitmap(@"e:/123.jpg"));                   e.Graphics.FillRectangle(mysbrush1, rect1);　        // (实心刷) 　　　　　　 e.Graphics.FillRectangle(mylbrush1, rect1);            //(梯度刷) 　　            e.Graphics.FillRectangle(myhbrush1, rect1);             //(阴影刷)                        e.Graphics.FillRectangle(mytextureBrush, rect1);       //(纹理刷)          } 注意 LinearGradientBrush 类的命名空间为  System.Drawing.Drawing2D
