Examples

The following example initializes an EnumerationOptions variable with an EnumerationOptions constructor and then gets all the instances of a WMI class and its subclasses.

using System;
using System.Management;
public class RemoteConnect
{
    public static void Main()
    {
        EnumerationOptions opt = new EnumerationOptions();
        opt.DirectRead = false;
        // 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"]);
    }
}

Imports System.Management
Public Class RemoteConnect

    Public Overloads Shared Function Main( _
    ByVal args() As String) As Integer

        Dim opt As New EnumerationOptions
        opt.DirectRead = False
        ' Will enumerate instances of the given class
        ' and any subclasses.
        opt.EnumerateDeep = True
        Dim mngmtClass As New ManagementClass("CIM_Service")
        Dim o As ManagementObject
        For Each o In mngmtClass.GetInstances(opt)
            Console.WriteLine(o("Name"))
        Next o

        Return 0
    End Function
End Class
