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));
