在醒目的WPF子线程未处理的异常 [英] Catching Unhandled Exceptions in Child Threads in WPF
问题描述
我有一个WPF应用程序,旋转了多个线程。我已经定义在App.xaml.cs一个DispatcherUnhandledException事件处理程序,显示详细的错误信息,并且此处理被调用每一个UI线程遇到异常的时间。问题是与子线程:其未处理的异常永远不会得到处理。我如何做到这一点。
I have a WPF application that spins off several threads. I have defined a DispatcherUnhandledException event handler in App.xaml.cs that displays a detailed error message, and this handler gets called every time the UI thread encounters an exception. The problem is with the child threads: their unhandled exceptions never get handled. How do I do this?
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
//...
}
修改发生STRONG>一旦未处理的异常,我想显示一个堆栈跟踪的错误信息,然后退出应用程序。
Once an unhandled exception occurs, I want to display an error message with a stack trace, and then exit the application.
推荐答案
尝试挂钩到 AppDomain.CurrentDomain.UnhandledException 事件也是如此。
Try hooking up to the AppDomain.CurrentDomain.UnhandledException event as well.
