我已经创建了一个C ++ DLL(它必须是C ++),它将.Net DLL与主机Web服务器联系起来。 .Net DLL将Web服务调用传递给C ++ DLL,该DLL也通过.Net DLL进行评估和响应。
类似的东西:
HSPWebService.DLL
-----------------------------------
HSPProxy.DLL | HSPWebServiceLib.DLL
-----------------------------------
HSPSendData.DLL
一切都像魅力一样。问题是DLL文件在网络共享(// myPc / share)中。我的应用程序日志显示错误0x80131515:
CreateAssemblyInstance错误:无法创建程序集实例。 (HR = 80131515)
在我的研究中,我发现发生了0x80131515错误,因为.Net框架默认情况下不会从外部源加载程序集。对于.Net项目,可以将选项设置为项目设置。但我在Visual Studio 2010上有一个C ++项目,我不知道在我的项目(或我的代码)上使用这个配置。有什么想法吗?
CreateAssemblyInstance函数:
HRESULT CHSPWebServiceObjectHost::CreateAssemblyInstance(_AppDomain* pDefAppDomain, CComPtr<IDispatch>& spDisp, LPCTSTR pszAsseblyName, LPCTSTR pszClassNameWithNamespace) const
{
spDisp = NULL;
REQUIRE_IN_POINTER(pDefAppDomain);
try
{
_bstr_t _bstrAssemblyName(pszAsseblyName);
_bstr_t _bstrszClassNameWithNamespace(pszClassNameWithNamespace);
//Creates an Assembly instance
CComPtr<_ObjectHandle> spObjectHandle;
HRESULT hr = pDefAppDomain->CreateInstanceFrom(_bstrAssemblyName, _bstrszClassNameWithNamespace, &spObjectHandle);
if (FAILED(hr))
{
Log(logDriver, _T("CHSPWebServiceObjectHost::CreateAssemblyInstance ERROR: Could not create an assembly instance. (hr=%08X)"), hr);
return hr;
}
CComVariant VntUnwrapped;
hr = spObjectHandle->Unwrap(&VntUnwrapped);
if (FAILED(hr))
{
Log(logDriver, _T("CHSPWebServiceObjectHost::CreateAssemblyInstance ERROR: Could not unwrap assembly object. (hr=%08X)"), hr);
return hr;
}
spDisp = VntUnwrapped.pdispVal;
}
catch (_com_error& e)
{
return e.Error();
}
return S_OK;
}
由StartCLR函数调用:
HRESULT CHSPWebServiceObjectHost::StartCLR(CComPtr<ICorRuntimeHost>& spRuntimeHost, CComPtr<IDispatch>& spDispHost) const
{
spRuntimeHost = NULL;
spDispHost = NULL;
//Retrieve a pointer to the ICorRuntimeHost interface
HRESULT hr = CorBindToRuntimeEx(L"v4.0.30319",
L"wks",
STARTUP_LOADER_SAFEMODE | STARTUP_CONCURRENT_GC,
CLSID_CorRuntimeHost,
IID_ICorRuntimeHost,
(void**)&spRuntimeHost);
if (FAILED(hr))
{
Log(logDriver, _T("CHSPWebServiceObjectHost::StartCLR ERROR: Could not load CLR into unmanaged host process. ( hr=%08X)"), hr);
return hr;
}
//Start the CLR
hr = spRuntimeHost->Start();
if (FAILED(hr))
{
Log(logDriver, _T("CHSPWebServiceObjectHost::StartCLR ERROR: Could not start CLR. (hr=%08X)"), hr);
return hr;
}
//Retrieve the IUnknown default AppDomain
CComPtr<IUnknown> spUnknown;
hr = spRuntimeHost->GetDefaultDomain(&spUnknown);
if (FAILED(hr))
{
Log(logDriver, _T("CHSPWebServiceObjectHost::StartCLR ERROR: Could not retrieve pointer to domain interface. ( hr=%08X)"), hr);
return hr;
}
CComQIPtr<_AppDomain> spDefAppDomain(spUnknown);
if (spDefAppDomain == NULL)
return E_NOINTERFACE;
CString strAssemblyFullPath = _T(".\\HSPSendData.dll");
return CreateAssemblyInstance(spDefAppDomain, spDispHost, strAssemblyFullPath, _T("Elipse.HSPWebService. HSPWebServiceHost"));
}

鉴于您的程序集位于网络共享上,您需要在app.config文件中添加<loadFromRemoteSources>
元素。例如:
<configuration>
<runtime>
<loadFromRemoteSources enabled="true"/>
</runtime>
</configuration>
您没有提及您的主机进程,但假设它是MyService.exe,则会进入MyService.exe.config文件。

显然 .NET更新已经解决了这个问题。我试图回溯哪个更新已经完成,但我无法找到它。
