C# Brush的使用

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)

}
