在WPF中捕获子线程中的未处理异常

Phi*_*hil 19 c# wpf multithreading exception-handling unhandled-exception

我有一个WPF应用程序,可以旋转几个线程.我在App.xaml.cs中定义了一个DispatcherUnhandledException事件处理程序,它显示详细的错误消息,每次UI线程遇到异常时都会调用此处理程序.问题在于子线程:它们未处理的异常永远不会得到处理.我该怎么做呢?

示例代码:

private void Application_DispatcherUnhandledException(object sender, System.Windows.Threading.DispatcherUnhandledExceptionEventArgs e)
{
    MessageBox.Show("detailed error message");
}

private void Application_Startup(object sender, StartupEventArgs e)
{
    //...
    //If an Exception is thrown here, it is handled
    //...

    Thread[] threads = new Thread[numThreads];
    for(int i = 0; i < numThreads; i++)
    {
        threads[i] = new Thread(doWork);
        threads[i].Start();
    }
}

private void doWork()
{
    //...
    //Exception thrown here and is NOT handled
    //...
}

编辑:一旦发生未处理的异常,我想显示带有堆栈跟踪的错误消息,然后退出应用程序.
