WMI:通过InstrumentationManager向WMI存储库注册程序集.RegisterAssembly



我正在尝试用C#（3.5版）编写WMI提供程序。它将是一个dll，我可以安装到GAC中，它通过管道与正在运行的服务通信。由于服务上有一个自定义的更新程序机制，我想用WMI存储库以编程方式注册和注销提供程序，而不是使用installutil.exe。

为了隔离我的问题并一次解决一个问题，我从以下链接开始使用示例提供程序：https://msdn.microsoft.com/en-us/library/cc268228.aspx.我可以将其构建为DLL，将其插入GAC（gacuti.exe），并通过InstallUtil.exe将其注册到WMI存储库。通过powershell对其进行的查询可以正常工作，当我使用wbemtest.exe时，我可以在其命名空间下看到其类。

但是，当我使用为使用InstrumentationManager编写的单独应用程序时，我尝试向WMI存储库注册程序集时失败了。RegisterAssembly。

下面是我尝试基于上面的示例以程序方式安装DLL。我非常感谢任何关于示例的指导或说明，这些示例显示了如何以这种方式实现提供者dll。

        {
            bool installing = true;
            string asmPath = "";
            if (!ParseInput(args, ref installing, ref asmPath))
            {
                PrintUsage();
                return;
            }
            Assembly myAssem = Assembly.Load(File.ReadAllBytes(asmPath));
            Console.WriteLine(myAssem.FullName);
            Console.WriteLine("Types contained in " + asmPath + " assembly");

            foreach (Type oType in myAssem.GetTypes())
            {
                Console.WriteLine("t" + oType.Name);
            }
            //Publish p = new Publish();
            //p.RegisterAssembly(myAssem);
            AssemblyInstaller wmi_installer = new AssemblyInstaller(myAssem, null);
            Console.WriteLine("--------------> Starting AssemblyInstaller.Install()");
            wmi_installer.Install(null);

                //Instrumentation.RegisterAssembly(myAssem);
                InstrumentationManager.RegisterAssembly(myAssem);

            }
            catch (Exception e)
            {
                Console.WriteLine("Exception Caught: {0}", e);
                Console.WriteLine("Exception Message: " + e.Message);
            }
        }
        static bool ParseInput(string[] args, ref bool installing, ref string asmPath)
        {
            if (args.Length < 2 || args[0].Equals("/h") || args[0].Equals("-h"))
            {
                return false;
            }
            asmPath = args[1];
            if (args[0].Equals("-i"))
            {
                installing = true;
                return true;
            }
            else if(args.Equals("-u"))
            {
                installing = false;
                return true;
            }
            return false;
        }
        static void PrintUsage()
        {
            System.Console.WriteLine("wmi_register_tool.exe nt-i <filename>nt-u <filename>");
        }
    }
}

我在它似乎成功的地方得到了以下输出，但在WMI存储库中找不到任何东西，所以RegisterAssembly一定没有成功插入它。

编辑：我试着更换Instrumentation。RegisterAssembly使用了以下代码，它再次毫无例外地运行完成，但它向控制台输出了更多信息，表明事情进展顺利。最后结果是一样的，我无法使用wbemtest.exe在WMI存储库中找到我的命名空间。

string[] installArgs = new String[] {
    "//logfile=",
    "//LogToConsole=false",
    "//ShowCallStack",
    myAssem.Location,
};
System.Configuration.Install.
ManagedInstallerClass.InstallHelper(installArgs);

在我试图让RegisterAssembly函数完成这项工作时，我错过了在搜索潜在依赖项时实现目标的事实。AssemblyInstaller。安装和组装安装程序。提交函数已成功将我的提供程序插入WMI存储库。我不确定RegisterAssembly是否删除了它和/或弄乱了条目，或者我是否只是通过持续测试弄乱了WMI存储库，但当我将测试VM重置为干净状态并使用一些新行运行代码时，AssemblyInstaller之后会导致异常。提交并在RegisterAssembly之前，我注意到我的提供程序已正确插入WMI存储库，并且我可以通过powershell查询它。

以下是在我手动将DLL放入GAC后成功将其安装到WMI存储库中的主要内容。

    static void Main(string[] args)
    {
        bool installing = true;
        string asmPath = "";
        if (!ParseInput(args, ref installing, ref asmPath))
        {
            PrintUsage();
            return;
        }
        Assembly myAssem = Assembly.Load(File.ReadAllBytes(asmPath));
        Console.WriteLine(myAssem.FullName);
        AssemblyInstaller wmi_installer = new AssemblyInstaller(myAssem, null);
        wmi_installer.Install(null);
        wmi_installer.Commit(null);
    }

为了完整起见，我将提供另一个版本，它可以在尝试之前卸载并检查程序集是否可以安装。

    static void Main(string[] args)
    {
        bool installing = true;
        bool installable = false;
        string asmPath = "";
        if (!ParseInput(args, ref installing, ref asmPath))
        {
            PrintUsage();
            return;
        }
        IDictionary mySavedState = new Hashtable();
        Assembly myAssem = Assembly.Load(File.ReadAllBytes(asmPath));
        Console.WriteLine(myAssem.FullName);
        AssemblyInstaller wmi_installer = new AssemblyInstaller(myAssem, null);
        if (installing)
        {
            try
            {
                AssemblyInstaller.CheckIfInstallable(asmPath);
                installable = true;
            }
            catch (Exception)
            {
                installable = false;
            }
            if (installable)
            {
                mySavedState.Clear();
                try
                {
                    wmi_installer.Install(mySavedState);
                    wmi_installer.Commit(mySavedState);
                }
                catch (Exception)
                {
                    wmi_installer.Rollback(mySavedState);
                }
            }
        }
        else
        {
            try
            {
                wmi_installer.Uninstall(null);
            }
            catch (Exception e)
            {
                Console.WriteLine("Uninstall failed due to: " + e.Message);
            }
        }
    }
