c# - 缺少 Win32_Service

Question

我有 C# 代码尝试从 WMI 对象加载某些属性 - Win32_Service。但它返回给我“System.Management.ManagementException:无效类”错误。

我的简化代码:

static void Main(string[] args)
{
    string serviceName = "AppFabricEventCollectionService";
    string propertyName = "StartName";
    var obj = GetProperty(serviceName, propertyName);
}

private static string GetProperty(string serviceName, string propertyName)
{
    using (ManagementObject obj2 = GetWindowsServiceManagementObject(serviceName))
    {
        return (obj2.GetPropertyValue(propertyName) as string);
    }
}
public static ManagementObject GetWindowsServiceManagementObject(string serviceName)
{
    return new ManagementObject(string.Format("Win32_Service.Name='{0}'", serviceName));
}

我还尝试通过 PowerShell 命令加载 WMI 对象列表 -

获取-WmiObject-列表 |选择名称

它返回 91 个对象，但缺少 Win32_Service 对象。我在谷歌上搜索了如何重新安装它，但没有找到。有没有办法以某种方式重新安装它？

谢谢

更新 1:Powershell 命令的输出:

PS C:\Windows\system32> Get-WmiObject Win32_Service
Get-WmiObject : Invalid class "Win32_Service"

尝试重新注册基类(当然是管理命令行...)
