在Winform的窗体中，存在背景图的情况下，不想在画面上加入按钮，只希望利用窗体自身的几个事件来实现按钮按下的效果，怎么样实现呢？
其实这也不难，只需要按照下列步骤即可实现，首先确定要按下的几个区域的坐标点和大小，准备好按下和弹出的图片，将这些坐标点和大小
组成一个个区域（使用GraphicsPath来完成）。然后使用几个Flage标志，标识是否区域的按下。具体实现的代码如下：
/// <summary>
/// 实时监控，酒位展示，酒柜介绍，网络订购4个按钮的位置参数
/// </summary>
int[,] BtnLocation = new int[4, 2]{{637,161},{683,269},{714,374},{637,478}};
/// <summary>
/// 4个按钮的Size参数
/// </summary>
Size BtnSize = new Size(285,92);
/// <summary>
/// 实时监控按钮是否按下的标志
/// </summary>
bool FlageMouseDownRealTime = false;
/// <summary>
/// 酒位展示按钮是否按下的标志
/// </summary>
bool FlageMouseDownWinePos = false;
/// <summary>
/// 酒柜介绍按钮是否按下的标志
/// </summary>
bool FlageMouseDownCupIntrol = false;
/// <summary>
/// 网络订购按钮是否按下的标志
/// </summary>
bool FlageMouseDownNetPurchase = false;
/// <summary>
/// 实时监控按钮的位置范围
/// </summary>
GraphicsPath gpRealTime = new GraphicsPath();
/// <summary>
/// 酒位展示按钮的位置范围
/// </summary>
GraphicsPath gpWinePos = new GraphicsPath();
/// <summary>
/// 酒柜介绍按钮的位置范围
/// </summary>
GraphicsPath gpCupIntrol = new GraphicsPath();
/// <summary>
/// 网络订购按钮的位置范围
/// </summary>
GraphicsPath gpNetPurchase = new GraphicsPath();
Graphics dc = null;
/// <summary>
/// 获取4个按钮的区域范围
/// </summary>
private void GetButtonGraphicPath()
{

new Point(BtnLocation[0,0]+BtnSize.Width,BtnLocation[0,1]+BtnSize.Height),
new Point(BtnLocation[0,0],BtnLocation[0,1]+BtnSize.Height)
};
gpRealTime.AddLines(pt);
pt = new Point[]{
new Point(BtnLocation[1,0],BtnLocation[1,1]),

new Point(BtnLocation[1,0]+BtnSize.Width,BtnLocation[1,1]+BtnSize.Height),

new Point(BtnLocation[2,0],BtnLocation[2,1]+BtnSize.Height)
};
gpCupIntrol.AddLines(pt);
pt = new Point[]{
new Point(BtnLocation[3,0],BtnLocation[3,1]),
new Point(BtnLocation[3,0]+BtnSize.Width,BtnLocation[3,1]),
new Point(BtnLocation[3,0]+BtnSize.Width,BtnLocation[3,1]+BtnSize.Height),
new Point(BtnLocation[3,0],BtnLocation[3,1]+BtnSize.Height)
};
gpNetPurchase.AddLines(pt);
}
private void InitialButtonsStyle()
{
GetButtonGraphicPath();
