我能够使用System.Management和StdRegProv (用于注册表)查询WMI类和注册表值。
我想改用Microsoft.Management.Infrastructure而不是System.Management。到目前为止，在网上的许多文章的帮助下，我可以用下面的代码做一个CIMSession并获得WMI类(例如Win32_OperatingSystem)等
代码语言：
javascript
复制
using Microsoft.Management.Infrastructure;
string Namespace = @"root\cimv2";
string OSQuery = "SELECT * FROM Win32_OperatingSystem";
CimSession mySession = CimSession.Create("Computer_B");
IEnumerable<CimInstance> queryInstance = mySession.QueryInstances(Namespace, "WQL", OSQuery);然而，使用Microsoft.Management.Infrastructure CimSession读取注册表项让我摸不着头脑。有没有人可以帮我提供一个实用的例子，或者告诉我公开的资源可以帮助我做到这一点。

这篇文章已经更新了几个月了，这里没有可用的代码，而且很难在网络上找到任何非抽象的东西。这是我用来帮助你处理WSMAN和获取WMI和注册表信息的一个类。
注意:如果您查找类的方法，即Win32_Service/Win32_Process，则可以停止和启动进程/服务。使用下面代码中的方法
GetParametersForMethod()
找出每个类都有哪些方法。
要获得注册表数据
Microsoft.Management.Infrastructure
，您需要使用
CimSession
类中的
InvokeMethod
方法。
要使用下面的类，请执行以下操作：
代码语言：
javascript
复制
string ComputerName = "SomeComputer";
string UserID = "SomeUser";
string Domain = "SomeDomain";
string Passwd = "SomePasswd";
WSManHelper WSMH = new WSManHelper(ComputerName,
Microsoft.Management.Infrastructure.Options.PasswordAuthenticationMechanism.Kerberos, Domain, UserID, Passwd);
if (WSMH.Connected)
WSMH.GetWMIDataFromSystem();
WSMH.EnumerateBaseSoftwareKeys();
// check out the data
foreach (string DisplayName in WSMH.RegSoftwareUninstall)
Console.WriteLine(DisplayName);
}使用以下内容创建新类：
代码语言：
javascript
