关于C#多屏幕显示器编程

在窗口的中间有一个System.Windows.Forms.PictureBox控件（该控件区域的面积为所在窗口的1/4），当该控件的大部分区域落在其中一台显示器时，在另一台显示器将不显示该控件，（该PictureBox控件将移动到主显示器所在的窗口区域）。
是否应该调用GetMonitorInfo？

首先你需要知道一个屏幕是如何分割成多个显示器显示的，即每个显示器显示多大region。
而在初始化picturebox的时候，你可以通过
Screen.PrimaryScreen.Bounds
来获得屏幕大小，至于控件的位置，你可以先转换到屏幕坐标，然后按照前面获得比例尺寸（一个屏幕是如何分割成多个显示器显示的，即每个显示器显示多大region），最后进行判断处理。

 

多屏幕编程简单么？
比如分辨率1024*768
第一个屏幕就是0~1024，第二个屏幕就是1025~2048，....
如果你要把某一画面显示在第二个屏幕。。。只要把它的x,y位置即可。。。

 

受了Knight94(愚翁)的启发，做了个测试，可以实现我需要的效果了，谢谢Knight94。
测试代码如下：
