LZ 直接给Button 的背景添加图片不行吗？LZ想要什么样的效果？
button1_Paint  事件中画
Graphics g = e.Graphics;
形状使用Region属性可以控制，绘制放在其Paint事件处理方法中。
自己做一个Button1.新建一个UserControl
2. Protected override void OnPaint(...)
   {
     Graphics g = e.Graphics;//建立画图对象
     GraphicsPath buttonPath = new GraphicsPath(); //自定义Button的形状;
     buttonPath.AddRectange(this.ClientRectange); //矩形Button;
     g.DrawImage((image),ClientRectange); //Image背景;//也可以用渐变色填充
      g.DrawPath(Pens.Black,buttonPath);
     g.DrawString(.....);
     ......
   }
   //鼠标事件
   private void MouseClick(...) {...}
   private void MouseEnter(...) {...}
   ......
3.生成就可以用了.
上图中,1-5图分别为素材图和窗体设计时截图,6为运行时效果图下面的代码是通过通过VB2008在线转换成的C#代码Graphics G;
Bitmap B_LEFT;
Bitmap B_TOP;
Bitmap B_BOTTOM;
Bitmap B_RIGHT;
Bitmap BP;
Bitmap B1;
Bitmap B_TR;

    矩形 = new Rectangle(0, 0, 物件.Width, 物件.Height);
    B1 = new Bitmap(矩形.Width, 矩形.Height);
    G = Graphics.FromImage(B1);
