一臺主機連接了2臺顯示器（2個顯卡），要求一個程序的兩個窗體在不同的顯示器上顯示：顯示器1 顯示From1，顯示器2 顯示From2。代碼及說明如下：
Form1不需要變更代碼，From2添加如下代碼：
// 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);
說明：
獲取當前系統連接的屏幕數量： Screen.AllScreens.Count();
獲取當前屏幕的名稱：string CurrentScreenName = Screen.FromControl(this).DeviceName;
獲取當前屏幕對象：Screen CurrentScreen = Screen.FromControl(this);
獲取當前鼠標所在的屏幕：Screen CurrentScreen = Screen.FromPoint(new Point(Cursor.Position.X, Cursor.Position.Y));
