从非托管C ++ EXE消耗托管C#DLL-无法启动CLR主机

问题描述：

你好，
这是我要运行的代码:

Hello,
Here is the code I''m trying to run:

HRESULT hr = S_OK;
ICLRMetaHost    *m_pMetaHost = NULL;
ICLRRuntimeInfo *m_pRuntimeInfo = NULL;
ICorRuntimeHost  *m_pHost = NULL;
       
//CorBindToRuntimeEx is deprecated, try this code instead
hr = CLRCreateInstance(CLSID_CLRMetaHost, IID_ICLRMetaHost, (LPVOID*) &m_pMetaHost);
if (hr != S_OK) 
	return hr;
hr = m_pMetaHost->GetRuntime (DOTNETVERSION, IID_ICLRRuntimeInfo, (LPVOID*) &m_pRuntimeInfo);
if (hr != S_OK)
	return hr;
hr = m_pRuntimeInfo->GetInterface(CLSID_CLRRuntimeHost, IID_ICLRRuntimeHost, (LPVOID*) &m_pHost );
       if (FAILED(hr)) return hr;
        
//Start the CLR
hr = m_pHost->Start();

尝试执行m_pHost-> Start()时，程序崩溃.

在输出窗口中，我遇到了第一次机会异常和访问冲突:
在sidebar.exe中的0x7c812afb处出现第一次机会异常:0x04242420:0x4242420.
``sidebar.exe'':已加载``C:\ WINDOWS \ assembly \ NativeImages_v4.0.30319_32 \ mscorlib \ 246f1a5abb686b9dcdf22d3505b08cea \ mscorlib.ni.dll''

程序"[0x508] sidebar.exe:本机"已退出，代码为-2146233082(0x80131506).

任何想法将不胜感激.

问候，
Mike

The program crashed upon trying to execute m_pHost->Start().

In the output window, I''m getting first-chance exceptions and an access violation:

Any ideas would be appreciated.

好，我想我发现了问题:

OK, I think I found the problem:

ICorRuntimeHost  *m_pHost = NULL;

应该更改为

should be changed to

ICLRRuntimeHost  *m_pHost = NULL;

此方法有一种完全不同的替代方法.这直接将.NET方法暴露给非托管方法.许多人会告诉你这是不可能的，但是事实并非如此.对于C#，C#/CLI和VB.NET，这是不可能的，但在IL中是可能的并且已标准化.实际上，您无需了解IL，有一种解决方案可将非托管导出自动添加到已编译的程序集.我从下面引用的一些CodeProject文章中知道这一点.

请查看我过去的解决方案以获取更多信息: ^ ].

There is a radically different alternative to this approach. This is directly exposing a .NET methods to the unmanaged. Many would tell you it is impossible, but this is not true. This is impossible for C#, C#/CLI and VB.NET, but possible and standardized in IL. You don''t need to know IL in fact, there is a solution automatically adding unmanaged export to your compiled assembly. I know it from some CodeProject articles referenced below.

Please see my past solution for more information: How can I use a dll created in Visual Basic 2008 in Visual Basic 6.0[^].
