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.
