Sty*_*s05 20 wpf execute event-handling
我不熟悉使用事件处理程序,我想知道是否有人或者可以指示我使用一些代码来演示如何使用将在Close/Closed事件上执行代码的事件处理程序?
我知道这可以做到,因为这个回答的问题:
但我需要一些方向.
谢谢=)

就是这个XAML
<Window ... Closing="Window_Closing" Closed="Window_Closed">
...
</Window>

Closing和Closed事件的代码
private void Window_Closing(object sender, System.ComponentModel.CancelEventArgs e)
{
...
}
private void Window_Closed(object sender, EventArgs e)
{
....
}

如果你想从后面的代码中完成所有操作,请将它放在windows .cs文件中
namespace WpfApplication1
{
/// <summary>
/// Interaction logic for MainWindow.xaml
/// </summary>
public partial class MainWindow : Window
{
public MainWindow()
{
InitializeComponent();
this.Closed += new EventHandler(MainWindow_Closed);
}
void MainWindow_Closed(object sender, EventArgs e)
{
//Put your close code here
}
}
}

如果你想参与xaml并参与代码,请在xaml中执行此操作
<Window x:Class="WpfApplication1.MainWindow"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
Title="MainWindow" Height="350" Width="525" Closed="MainWindow_Closed">
<Grid>
</Grid>
</Window>

这在.cs
namespace WpfApplication1
{
/// <summary>
/// Interaction logic for MainWindow.xaml
/// </summary>
public partial class MainWindow : Window
{
public MainWindow()
{
InitializeComponent();
}
void MainWindow_Closed(object sender, EventArgs e)
{
//Put your close code here
}
}
}

以上示例您可以应用于xaml应用程序中的任何表单.您可以有多个表单.如果要为整个应用程序退出过程应用代码,请将app.xaml.cs文件修改为此文件
namespace WpfApplication1
{
/// <summary>
/// Interaction logic for App.xaml
/// </summary>
public partial class App : Application
{
protected override void OnExit(ExitEventArgs e)
{
try
{
//Put your special code here
}
finally
{
base.OnExit(e);
}
}
}
}
