WPF中实现关闭主程序方法

需求:需要在许多子窗体中关闭整个程序(WPF)

winform实现:Application.Exit();

WPF实现:

    App.xaml文件:

     <Application x:Class="pc.App"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    StartupUri="Windows1.xaml" ShutdownMode="OnExplicitShutdown">

   Windows1.xaml文件(部分):

    <Button Margin="37,0,15,15" Style="{DynamicResource btn_Exit}" Content="Button" Grid.Column="2" Grid.Row="3" Height="41" VerticalAlignment="Bottom" Width="100" x:Name="btn_Exits" Click="btn_Exits_Click" />

   Windows1.xaml.cs文件(部分):

     private void btn_Exits_Click(object sender, RoutedEventArgs e)
        {
            Application.Current.Shutdown();
           
        }

十分简单!此后只需在按钮事件中加入Application.Current.Shutdown(),即可退出程序
