wpf 多屏显示

wpf需要在分屏上显示窗体代码：

?

1 2 3 4 5 6 7 8 9 10 11 12 13

<Window x:Class="WpfApp1.MainWindow"         xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"         xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"         xmlns:d="http://schemas.microsoft.com/expression/blend/2008"         xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"         xmlns:local="clr-namespace:WpfApp1"           xmlns:vlc="clr-namespace:Vlc.DotNet.Wpf;assembly=Vlc.DotNet.Wpf"         mc:Ignorable="d"         Title="MainWindow" Height="450" Width="800">     <Grid>         <vlc:VlcControl x:Name="vlcControl" Loaded="vlcControl_Loaded" MouseMove="vlcControl_MouseMove"/>     </Grid> </Window>

需要在分屏显示的窗体后台代码

?

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18

#region 分屏显示               this.Loaded += (s, e) =>                      {                          foreach (Screen scr in Screen.AllScreens)                          {                              if (!scr.Primary)                              {                                  LogHelper.WriteLog(GetType(), "进入Screen");                           //设置窗体位置                           WindowStartupLocation = WindowStartupLocation.Manual;                                  Left = scr.WorkingArea.Left;                                  Top = scr.WorkingArea.Top;                                  WindowState = WindowState.Maximized;                                  break;                              }                          }                      };               #endregion

　　

实现原理

假设屏幕分辨率是1920*1080，有两屏幕，多屏的情况下主屏的左上角的坐标为（0，0），第二个屏幕左上角坐标是（1920,0）。双屏显示就是让窗体自动偏移到指定的屏幕中。

例如：

Left = scr.WorkingArea.Left;
Top = scr.WorkingArea.Top;

注意事项

需要特别注意：Window.WindowState属性的设置，如果在Xaml代码中直接设置最大化，那么无论后续如何设置分屏窗口都会直接显示在主屏幕中。
