C#中的Powershell命令

Question

我试图查询root\CIMV2名称空间中的所有WMI类的名称.有没有办法使用powershell命令在C#中检索此信息？

Answer 1

我不确定你为什么提到PowerShell; 你可以在纯C#和WMI(System.Management名称空间,即)中执行此操作.

要获取所有WMI类的列表,请使用以下SELECT * FROM Meta_Class查询:

using System.Management;
...

try
{
    EnumerationOptions options = new EnumerationOptions();
    options.ReturnImmediately = true;
    options.Rewindable = false;

    ManagementObjectSearcher searcher =
        new ManagementObjectSearcher("root\\cimv2", "SELECT * FROM Meta_Class", options);

    ManagementObjectCollection classes = searcher.Get();

    foreach (ManagementClass cls in classes)
    {
        Console.WriteLine(cls.ClassPath.ClassName);
    }
}
catch (ManagementException exception)
{
    Console.WriteLine(exception.Message);
}

Answer 2

沿着基思的方法

using System;
using System.Management.Automation;

namespace ConsoleApplication1
{
    class Program
    {
        static void Main(string[] args)
        {
            var script = @" 
                Get-WmiObject -list -namespace root\cimv2 | Foreach {$_.Name}
            ";

            var powerShell = PowerShell.Create();
            powerShell.AddScript(script);

            foreach (var className in powerShell.Invoke())
            {
                Console.WriteLine(className);
            }
        }
    }
}
