The following example shows how to initialize a ManagementClass variable with a ManagementClass constructor and then get all the instances of a WMI class and its subclasses.

using System;
using System.Management;

public class Sample 
{    
    public static void Main() 
    {
        EnumerationOptions opt = new EnumerationOptions();
        // Will enumerate instances of the given class and any subclasses.
        opt.EnumerateDeep = true;
        ManagementClass c = new ManagementClass("CIM_Service");
        foreach (ManagementObject o in c.GetInstances(opt))
            Console.WriteLine(o["Name"]);
