Winform窗口实现多显示屏显示的2种方法

一台主机连接了2台显示器（2个显卡），要求一个程序的两个窗体在不同的显示器上显示：显示器1 显示from1，显示器2  显示from2。代码及说明如下：

form1不需要变更代码，from2添加如下代码：

// 方法一：

from2 frm2 = new from2();
if (screen.allscreens.count() != 1)
{
  frm2.left = screen.allscreens[0].bounds.width;
  frm2.top = 0;
  frm2.size = new system.drawing.size(screen.allscreens[1].bounds.width, screen.allscreens[1].bounds.height);
}
// 方法二：
   this.left = ((screen.allscreens[1].bounds.width - this.width) / 2);
   this.top = ((screen.allscreens[1].bounds.height - this.height) / 2);
   this.size = new system.drawing.size(screen.allscreens[1].bounds.width, screen.allscreens[1].bounds.height);

说明：
获取当前系统连接的屏幕数量： screen.allscreens.count();
获取当前屏幕的名称：string currentscreenname = screen.fromcontrol(this).devicename;
获取当前屏幕对象：screen currentscreen = screen.fromcontrol(this);
获取当前鼠标所在的屏幕：screen currentscreen = screen.frompoint(new point(cursor.position.x, cursor.position.y));
