如何停止 CLR 主机?

我有C++注入目标程序的dll，并希望从中加载C#脚本，为此我创建了一个包装器，该包装器从C++dll获取函数并托管clr以加载C#应用程序。我像这样调用 CLR 托管线程，但我需要在运行时更改 C# 脚本，因此需要先卸载此脚本。我该怎么做？如何从线程中未运行的其他功能停止CLR托管？

DWORD WINAPI CreateDotNetRunTime(LPVOID lpParam)
{
ICLRRuntimeHost* lpRuntimeHost = NULL;
ICLRRuntimeInfo* lpRuntimeInfo = NULL;
ICLRMetaHost* lpMetaHost = NULL;
FILE* file;

LPWSTR AppPath = new WCHAR[_MAX_PATH];
::GetModuleFileNameW((HINSTANCE)&__ImageBase, AppPath, _MAX_PATH);

std::wstring tempPath = AppPath;
int index = tempPath.rfind('');
tempPath.erase(index, tempPath.length() - index);
tempPath += Assembly;

fopen_s(&file, Log, "a+");

HRESULT hr = CLRCreateInstance(
CLSID_CLRMetaHost, 
IID_ICLRMetaHost, 
(LPVOID*)&lpMetaHost
);

if (FAILED(hr))
{
fprintf(file, "Failed to create CLR instance.n");
fflush(file);
}

hr = lpMetaHost->GetRuntime(
L"v4.0.30319", 
IID_PPV_ARGS(&lpRuntimeInfo)
);

if (FAILED(hr))
{
fprintf(file, "Getting runtime failed.n");
fflush(file);

lpMetaHost->Release();
}

BOOL fLoadable;
hr = lpRuntimeInfo->IsLoadable(&fLoadable);

if (FAILED(hr) || !fLoadable)
{
fprintf(file, "Runtime can't be loaded into the process.n");
fflush(file);

lpRuntimeInfo->Release();
lpMetaHost->Release();
}

hr = lpRuntimeInfo->GetInterface(
CLSID_CLRRuntimeHost, 
IID_PPV_ARGS(&lpRuntimeHost)
);

if (FAILED(hr))
{
fprintf(file, "Failed to acquire CLR runtime.n");
fflush(file);

lpRuntimeInfo->Release();
lpMetaHost->Release();
}

hr = lpRuntimeHost->Start();

if (FAILED(hr))
{
fprintf(file, "Failed to start CLR runtime.n");
fflush(file);

lpRuntimeHost->Release();
lpRuntimeInfo->Release();
lpMetaHost->Release();
}

DWORD dwRetCode = 0;

hr = lpRuntimeHost->ExecuteInDefaultAppDomain(
(LPWSTR)tempPath.c_str(), 
Class,
Method, 
Param, 
&dwRetCode
);

if (FAILED(hr))
{
fprintf(file, "Unable to execute assembly.n");
fflush(file);

lpRuntimeHost->Stop();
lpRuntimeHost->Release();
lpRuntimeInfo->Release();
lpMetaHost->Release();
}

fclose(file);

return 0;
}

调用此：

CreateThread(NULL, NULL, CreateDotNetRunTime, NULL, NULL, NULL);
