[C#] 在指定螢幕顯示視窗

首先要引入命名空間

1. using Screen = System.windows.Forms.Screen;

自訂一個方法用來處理在指定螢幕顯示的功能

1. void ShowOnMonitor(Window win, int monitorIndex)
   
2. {
   
3.     int screenCount = Screen.AllScreens.Count();
   
4.     if (monitorIndex >= screenCount) monitorIndex = 0;
   
5. 
   
6.     Screen sc = Screen.AllScreens[monitorIndex];
   
7. 
   
8.     win.WindowStartupLocation = WindowStartupLocation.Manual;
   
9.     win.Top = sc.WorkingArea.Top;
   
10.     win.Left = sc.WorkingArea.Left;
    
11.     win.Width = sc.WorkingArea.Width;
    
12.     win.Height = sc.WorkingArea.Height;
    
13.     win.Loaded += Window_Loaded;
    
14. }
    

複製代碼

在視窗的 Loaded 事件加入上面的方法

1. private void Window_Loaded(object sender, RoutedEventArgs e)
   
2. {
   
3.     var senderWindow = sender as Window;
   
4.     if (null == senderWindow) return;
   
5.     senderWindow.WindowState = WindowState.Maximized;
   
6. }
