.net - 将托管 DLL 注入(inject) .net 4.0 应用程序

Question

我已经使用引导加载程序 dll(在 c++ 中)成功地将托管 DLL 注入(inject)到 .net 3.5 应用程序中，然后在(c#)中使用我的“有效负载”dll。

当我尝试对 .net 4.0 应用程序执行此操作时，它总是崩溃。

引导加载程序 C++:

    #include "MSCorEE.h"

    void StartTheDotNetRuntime()
    {
        // Bind to the CLR runtime..
        ICLRRuntimeHost *pClrHost = NULL;
        HRESULT hr = CorBindToRuntimeEx(
        NULL, L"wks", 0, CLSID_CLRRuntimeHost,
        IID_ICLRRuntimeHost, (PVOID*)&pClrHost);

        hr = pClrHost->Start();

        // Okay, the CLR is up and running in this (previously native) process.
        // Now call a method on our managed C# class library.
        DWORD dwRet = 0;
        hr = pClrHost->ExecuteInDefaultAppDomain(
             L"payload.dll",
             L"MyNamespace.MyClass", L"MyMethod", L"MyParameter", &dwRet);

        // Optionally stop the CLR runtime (we could also leave it running)
        hr = pClrHost->Stop();

       // Don't forget to clean up.
       pClrHost->Release();
    }

有效负载 C#:

    using System;using System.Collections.Generic;using System.Linq;using System.Text;using System.Windows.Forms;

    namespace MyNamespace
    {
       public class MyClass
       {
          // This method will be called by native code inside the target process...
          public static int MyMethod(String pwzArgument)
         {
             MessageBox.Show("Hello World");
             return 0;
         }

       }
    }

我尝试使用以下修复程序，但无济于事，有什么想法吗？
使固定？？:

  hr = pMetaHost->GetRuntime(L"v4.0.30319", IID_ICLRRuntimeInfo, (LPVOID*)&lpRuntimeInfo);

.NET 4.0 更改了接口(interface)。而不是使用 CorBindToRuntimeEx您应该使用新的 ICLRMetaHost interface .

代码可能如下所示(没有错误检查):

ICLRMetaHost *pMetaHost = NULL;
CLRCreateInstance(CLSID_CLRMetaHost, IID_ICLRMetaHost, (LPVOID*)&pMetaHost);

ICLRRuntimeInfo *pRuntimeInfo = NULL;
pMetaHost->GetRuntime(L"v4.0.30319", IID_ICLRRuntimeInfo, (LPVOID*)&pRuntimeInfo);

ICLRRuntimeHost *pClrRuntimeHost = NULL;
pRuntimeInfo->GetInterface(CLSID_CLRRuntimeHost, IID_ICLRRuntimeHost, (LPVOID*)&pClrRuntimeHost);

pClrRuntimeHost->Start();
