如何知道未处理的异常发生在哪里？

Question

When I run the app, I keep getting this error:

System.ArgumentException: Value does not fall within the expected range.

I don't know where this error occurs exactly or what is the cause. Isn't it possible to know that from:

private void Application_UnhandledException(object sender, ApplicationUnhandledExceptionEventArgs e)
{
    if (Debugger.IsAttached)
    {
        // An unhandled exception has occurred; break into the debugger
        Debugger.Break();
    }
}

in App.xaml ?

How can I know where the unhandled exception occurs? thanks

Answer 1

The following code will print the message and stack trace. You can get where the exception occured from the stackTrace.

private void Application_UnhandledException(object sender, ApplicationUnhandledExceptionEventArgs e)
{
    if (Debugger.IsAttached)
    {
        MessageBox.Show(e.ExceptionObject.Message + "\r\n" + e.ExceptionObject.StackTrace, "Error", MessageBoxButton.OK);

    }
}
