例外的本地线程崩溃无一例外.NET应用程序线程、应用程序、NET

我已经发现了这样一个场景，我的.NET应用程序会意外崩溃而不引发任何异常。我想，至少， AppDomain.UnhandledException 曾在这种情况下，为了使我至少有一些信息记录错误和present用户

I have discovered a scenario where my .Net application will crash unexpectedly without raising any exceptions. I would like that, at least, AppDomain.UnhandledException worked in this case, in order to enable me at least to log the error and present the user with some information.

在这种情况下，我有一个.NET程序集（姑且称之为 A ）与互操作调用本机DLL（我们称之为 B ）。 B创建一个线程，并抛出;没有任何人来捕获异常，我希望它一路走下去堆栈，回到我的托管应用程序，然后最终成为一个未处理的异常。

In this scenario, I have an .Net assembly (let's call it A) with an interop call to a native DLL (which we will call B). B creates a thread and throws; Without anyone to catch the exception, I'd expect it to go all the way up the stack, back into my managed application, and then finally become an unhandled exception.

在这一点上我希望操作系统到手的控制权交还给净，这会叫 AppDomain.UnhandledException ，并与该，我的应用程序将结束。然而，该呼叫不会被制成。

At this point I would expect the OS to hand the control back to .Net, which would call AppDomain.UnhandledException and, with that, my application would end. However, the call is never made.

下面我包含足够的信息来重现问题。它可以忽略不计。

的Program.cs 的

internal class Program
{
    public static void Main()
    {
        AppDomain.CurrentDomain.UnhandledException += _currentDomainUnhandledException;
        try
        {
            BugDllInterop.ErrorMethod(0);
        }
        catch (Exception e)
        {
            Console.WriteLine("Exception: " + e.GetType().Name);
        }            

        Console.WriteLine("Clean exit.");
    }

    private static void _currentDomainUnhandledException(object sender, UnhandledExceptionEventArgs e)
    {
        Console.WriteLine("Exception trapped.");
    }
}

BugDllInterop.cs 的

public static class BugDllInterop
{
    private const string BUG_DLL = "InteropExceptions.BugDll.dll";

    [DllImport(BUG_DLL, CallingConvention = CallingConvention.Cdecl)]
    public extern static void ErrorMethod(int i);
}

BugDll.h 的

// INCLUSION GUARD
#pragma once

#define DllExport __declspec(dllexport) 

extern "C" 
{
    DllExport void ErrorMethod(int i);
}

BugDll.cpp 的

// HEADER /////////////////////////////////////////////////////////////////////
#include "BugDll.h"

// LIBRARIES //////////////////////////////////////////////////////////////////
#include <windows.h>
#include <fstream>
#include <iostream>
#include <time.h>

using namespace std;

// FUNCTIONS //////////////////////////////////////////////////////////////////

DWORD WINAPI threadMethod(LPVOID lpParameter)
{
    throw 0;

    return 0;
}

void ErrorMethod(int i)
{

    DWORD myThreadID;
    HANDLE myHandle = CreateThread(0, 0, threadMethod, 0, 0, &myThreadID);
    WaitForSingleObject(myHandle, 3000);
    CloseHandle(myHandle);

}

此外，我需要的就是这样的 AppDomain.UnhandledException 事件引发。当然，如果有人知道如何正确的，以保持应用程序正常处理的异常，这将是更好的。

Again, my desired is just that the AppDomain.UnhandledException event is raised. Of course, if anyone knows how to properly handle the exception in order to keep the application alive, it would be even better.
