我可以使用System.Management和StdRegProv（用于注册表）查询WMI类和注册表值。
我想转而使用Microsoft.Management.Infrastructure而不是System.Management。到目前为止，在网上很多文章的帮助下，我可以做一个CIMSession并获得WMI类（例如Win32_OperatingSystem）等，代码如下
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);
但是，使用Microsoft.Management.Infrastructure CimSession读取注册表项是我的不足之处。有人可以帮助指导一个工作示例或指向我公开可用的资源，这可以帮助我实现这一目标。
您可以使用ORMi（https://github.com/nicoriff/ORMi）库。完成您正在尝试的内容非常容易：
WMIHelper helper = new WMIHelper("root\\CimV2");
var devices = helper.Query("SELECT * FROM Win32_OperatingSystem");
您可以在存储库页面上找到更多信息。您可以返回强类型对象。
自这篇文章更新以来已经有几个月了，这里没有工作代码，也很难在网上找到任何不抽象的内容。这是我参与的一个课程，用于帮助您使用WSMAN并获取WMI和注册表信息。
注意：如果查找类的方法，即Win32_Service / Win32_Process，则可以停止并启动进程/服务。使用下面的代码中的方法GetParametersForMethod()来找出每个类有哪些方法。
要获取注册表数据Microsoft.Management.Infrastructure，您需要使用InvokeMethod类中的CimSession方法。
要使用下面的课程，请执行以下操作：
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：
