c ++ clr host可以执行c＃但不能执行vb.net

Question

我有这个代码可以使用clr运行时主机从非托管c ++程序执行c＃assembly 它适用于c＃，但是使用vb.net它不起作用，尽管两种语言都被编译为il代码并运行.net框架

这是代码：

#include <stdio.h>
#include <tchar.h>
#include <metahost.h>
#pragma comment(lib, "MSCorEE.lib")

#import "C:\Windows\Microsoft.NET\Framework\v2.0.50727\mscorlib.tlb" 
raw_interfaces_only \
high_property_prefixes("_get","_put","_putref")     \
rename("ReportEvent", "InteropServices_ReportEvent")
using namespace mscorlib;



unsigned char rawData[] = {
// .net exe bytes
};

#define RAW_ASSEMBLY_LENGTH sizeof(rawData);

int _tmain(int argc, _TCHAR* argv[])
{
ICLRMetaHost* pMetaHost = NULL;

HRESULT hr;

/* Get ICLRMetaHost instance */

hr = CLRCreateInstance(CLSID_CLRMetaHost, IID_ICLRMetaHost, 
(VOID**)&pMetaHost);

if(FAILED(hr))
{
    printf("[!] CLRCreateInstance(...) failed\n");

    getchar();

    return -1;
}

printf("[+] CLRCreateInstance(...) succeeded\n");

ICLRRuntimeInfo* pRuntimeInfo = NULL;

/* Get ICLRRuntimeInfo instance */

hr = pMetaHost->GetRuntime(L"v2.0.50727", IID_ICLRRuntimeInfo, 
(VOID**)&pRuntimeInfo);

if(FAILED(hr))
{
    printf("[!] pMetaHost->GetRuntime(...) failed\n");

    getchar();

    return -1;
}

printf("[+] pMetaHost->GetRuntime(...) succeeded\n");

BOOL bLoadable;

/* Check if the specified runtime can be loaded */

hr = pRuntimeInfo->IsLoadable(&bLoadable);

if(FAILED(hr) || !bLoadable)
{
    printf("[!] pRuntimeInfo->IsLoadable(...) failed\n");

    getchar();

    return -1;
}

printf("[+] pRuntimeInfo->IsLoadable(...) succeeded\n");

ICorRuntimeHost* pRuntimeHost = NULL;

/* Get ICorRuntimeHost instance */

hr = pRuntimeInfo->GetInterface(CLSID_CorRuntimeHost, IID_ICorRuntimeHost,

if(FAILED(hr))
{
    printf("[!] pRuntimeInfo->GetInterface(...) failed\n");

    getchar();

    return -1;
}

printf("[+] pRuntimeInfo->GetInterface(...) succeeded\n");

/* Start the CLR */

hr = pRuntimeHost->Start();

if(FAILED(hr))
{
    printf("[!] pRuntimeHost->Start() failed\n");

    getchar();

    return -1;
}

printf("[+] pRuntimeHost->Start() succeeded\n");

IUnknownPtr pAppDomainThunk = NULL;

hr = pRuntimeHost->GetDefaultDomain(&pAppDomainThunk);

if(FAILED(hr))
{
    printf("[!] pRuntimeHost->GetDefaultDomain(...) failed\n");

    getchar();

    return -1;
}

printf("[+] pRuntimeHost->GetDefaultDomain(...) succeeded\n");

_AppDomainPtr pDefaultAppDomain = NULL;

/* Equivalent of System.AppDomain.CurrentDomain in C# */

hr = pAppDomainThunk->QueryInterface(__uuidof(_AppDomain), (VOID**) 
&pDefaultAppDomain);

if(FAILED(hr))
{
    printf("[!] pAppDomainThunk->QueryInterface(...) failed\n");

    getchar();

    return -1;
}

printf("[+] pAppDomainThunk->QueryInterface(...) succeeded\n");

_AssemblyPtr pAssembly = NULL;

SAFEARRAYBOUND rgsabound[1];

rgsabound[0].cElements = RAW_ASSEMBLY_LENGTH;

rgsabound[0].lLbound   = 0;

SAFEARRAY* pSafeArray  = SafeArrayCreate(VT_UI1, 1, rgsabound);

void* pvData = NULL;

hr = SafeArrayAccessData(pSafeArray, &pvData);

if(FAILED(hr))
{
    printf("[!] SafeArrayAccessData(...) failed\n");

    getchar();

    return -1;
}

printf("[+] SafeArrayAccessData(...) succeeded\n");

memcpy(pvData, rawData, RAW_ASSEMBLY_LENGTH);

hr = SafeArrayUnaccessData(pSafeArray);

if(FAILED(hr))
{
    printf("[!] SafeArrayUnaccessData(...) failed\n");

    getchar();

    return -1;
}

printf("[+] SafeArrayUnaccessData(...) succeeded\n");

/* Equivalent of System.AppDomain.CurrentDomain.Load(byte[] rawAssembly) */

hr = pDefaultAppDomain->Load_3(pSafeArray, &pAssembly);

if(FAILED(hr))
{
    printf("[!] pDefaultAppDomain->Load_3(...) failed\n");

    getchar();

    return -1;
}

printf("[+] pDefaultAppDomain->Load_3(...) succeeded\n");

_MethodInfoPtr pMethodInfo = NULL;

/* Assembly.EntryPoint Property */

hr = pAssembly->get_EntryPoint(&pMethodInfo);

if(FAILED(hr))
{
    printf("[!] pAssembly->get_EntryPoint(...) failed\n");

    getchar();

    return -1;
}

printf("[+] pAssembly->get_EntryPoint(...) succeeded\n");

VARIANT retVal;
ZeroMemory(&retVal, sizeof(VARIANT));

VARIANT obj;
ZeroMemory(&obj, sizeof(VARIANT));
obj.vt = VT_NULL;

//TODO! Change cElement to the number of Main arguments
SAFEARRAY *psaStaticMethodArgs = SafeArrayCreateVector(VT_VARIANT, 0, 1);

/* EntryPoint.Invoke(null, new object[0]) */

hr = pMethodInfo->Invoke_3(obj, psaStaticMethodArgs, &retVal); // fails here

if(FAILED(hr))
{
    printf("[!] pMethodInfo->Invoke_3(...) failed, hr = %X\n", hr);

    getchar();

    return -1;
}

printf("[+] pMethodInfo->Invoke_3(...) succeeded\n");

getchar();

return 0;
}

当我使用vb bytes时，我得到了这个：

[！] pMethodInfo-＆gt; Invoke_3（...）失败，hr = 80131604

我尝试过使用.net框架版本v4和v2并更改了参数数量但没有效果
