C++ cli 应用程序关闭时崩溃-使用混合模式DLL

程序关闭时，我的应用程序会崩溃。否则运行正常。
设置：
-Visual Studio 2012（x64 Windows 7）
-C++/CLI与本机代码DLL的混合（本机代码为Boost Asio）
-与DLL链接的CLR控制台应用程序

当我“调试”崩溃时，会显示相关消息：

未处理的异常。。。0xC002001:字符串绑定无效

我找到了这个描述错误的MS简介：
概括地说，当托管代码与非托管代码不正确地混合时，就会发生这种情况。 但是，我无法确定我的代码在哪里被错误地混合

文件“unmanagedboostststuff.cpp”的属性设置为

不支持公共语言运行时

我了解到，当您在include语句周围包含一个带有本机代码的头时，如下所示：

// #pragma unmanaged
// push managed state on to stack and set unmanaged state
#pragma managed(push, off)
#include "UnmanagedBoostStuff.h"
// #pragma managed
#pragma managed(pop)

DLL文件“mixedcrldll.h”

// MixedClrDLL.h

#pragma once

/* 
 *
 * Add the following preprocessor definitions:
 *   BOOST_ALL_DYN_LINK
 *   _WIN32_WINNT=0x0501
 *
 * Turn off Precompiled Headers
 *
 * Make sure CLR is turned off for native code.
 */   

// #pragma unmanaged
// push managed state on to stack and set unmanaged state
#pragma managed(push, off)
#include "UnmanagedBoostStuff.h"
// #pragma managed
#pragma managed(pop)

using namespace System;

namespace MixedClrDLL {

    public ref class SerialPort

        }

    private:
        bool m_isDisposed;
    };
}

DLL文件“mixedcrldll.cpp”

// This is the main DLL file.

#include "stdafx.h"

#include <iostream>

using namespace MixedClrDLL;
using namespace System;

SerialPort::SerialPort(System::String ^portName, int timeoutMillis)

    // Marshal the managed string to unmanaged memory. 
    char* stringPointer = (char*) Marshal::StringToHGlobalAnsi(portName).ToPointer();

    try
    {   
        nativeClassPtr = new BlockingReader(stringPointer, timeoutMillis);
    }

    catch ( Runtime::InteropServices::SEHException^ )

      std::cout<< "caught an SEH Exception in SerialPort constructor" << std::endl;
      nativeClassPtr = nullptr;
      throw("Invalid com-port name");

“Viorel_”在另一个论坛上提供了答案。 基本上就是让所有的代码

都得到管理

。通过取出我列出的pragmas并将选项放回本机模块上的

/clr

。

这在退出时阻止了应用程序崩溃。

发布堆栈跟踪。我一定会喜欢那些胆小的匿名者-1'ers:）
