[英]How to make WPF crashing application shut down immediately ( immediately is the keyword)?
I have a WPF application, which in the case of unhandled exception, I want to 我有一个WPF应用程序,对于未处理的异常,我想
For the second purpose, I can easily listen to the AppDomain.CurrentDomain.UnhandledException
event and then restart the same app using the Process.Start
. 第二个目的, 我可以轻松地监听AppDomain.CurrentDomain.UnhandledException
事件,然后使用Process.Start
重新启动同一应用程序 。
But for the first purpose, I that after the exception occurs, the application will freeze for quite a while before finally going away. 但是,出于第一个目的,我认为在异常发生之后,应用程序将冻结一段时间,直到最终消失。 I try to speed up the process by putting in the 我尝试通过添加
Application.Current.Shutdown();
And yet, it still takes quite a while for the program to freeze and then only finally shut down. 但是,程序冻结仍然需要花费相当长的时间,然后才最终关闭。
Why is this the case? 为什么会这样呢?
And how I can make the old application shut down immediately? 以及如何使旧应用程序立即关闭? An unhandled exception in my application is already bad enough, I don't need the dying application to linger long enough and to embarrass me. 我的应用程序中未处理的异常已经很糟糕,我不需要垂死的应用程序徘徊足够长的时间并使我感到尴尬。

public partial class App : Application
{
protected override void OnStartup(StartupEventArgs e)
{
base.OnStartup(e);
AppDomain.CurrentDomain.UnhandledException += CurrentDomainOnUnhandledException;
DispatcherUnhandledException += CurrentApplicationOnDispatcherUnhandledException;
}
private void CurrentApplicationOnDispatcherUnhandledException(object sender, DispatcherUnhandledExceptionEventArgs e)
{
}
private void CurrentDomainOnUnhandledException(object sender, UnhandledExceptionEventArgs e)
{
Application.Current.Shutdown();
}
}
public partial class MainWindow : Window
{
public MainWindow()
{
InitializeComponent();
}
private void button_Click(object sender, RoutedEventArgs e)
{
throw new NotFiniteNumberException();
}
}
