C# 在winform画面上点击某个区域造成按钮按下效果的方法

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;
