public:

public System.Management.ManagementObjectCollection GetSubclasses ();

member this.GetSubclasses : unit -> System.Management.ManagementObjectCollection

Public Function GetSubclasses () As ManagementObjectCollection

Returns

A collection of the ManagementObject objects that represent the subclasses of the WMI class.

Examples

The following example uses the GetSubclasses method to list the subclasses to the CIM_LogicalDisk class. For more information, see CIM_LogicalDisk.

using System;
using System.Management;

public class Sample
{
    public static void Main()
    {
        ManagementClass c =
            new ManagementClass("CIM_LogicalDisk");

        foreach (ManagementClass r in c.GetSubclasses())
        {
            Console.WriteLine(
                "Instances of {0} are sub-classes",
                r["__CLASS"]);
        }

        foreach (ManagementClass r in c.GetRelationshipClasses())
        {
            Console.WriteLine(
                "{0} is a relationship class to " +
                c.ClassPath.ClassName,
                r["__CLASS"]);

            foreach (ManagementClass related in c.GetRelatedClasses(
                null, r.ClassPath.ClassName,
                "Association", null, null, null, null))

member this.GetSubclasses : System.Management.EnumerationOptions -> System.Management.ManagementObjectCollection

Public Function GetSubclasses (options As EnumerationOptions) As ManagementObjectCollection

Parameters

Returns

A collection of the ManagementObject objects representing the subclasses of the WMI class, according to the specified options.

Examples

The following example shows how to initialize a ManagementClass variable with a ManagementClass constructor and then receive the subclasses of the WMI class passed into the constructor.

using System;
using System.Management;

public class Example
{
    public static void Main()
    {
        EnumerationOptions opt = new EnumerationOptions();
        // Causes return of deep subclasses
        // as opposed to only immediate ones.
        opt.EnumerateDeep = true;
        ManagementObjectCollection subclasses = (new
            ManagementClass("CIM_LogicalDisk")).GetSubclasses(opt);
        foreach(ManagementClass subclass in subclasses)
        {
            Console.WriteLine( "Subclass found: {0}" ,
                subclass["__CLASS"]);
        }

        return;
    }
}

Imports System.Management

Public Class Sample

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

        Dim opt As New EnumerationOptions

        ' Causes return of deep subclasses
        ' as opposed to only immediate ones.
        opt.EnumerateDeep = True

        Dim cls As New ManagementClass("CIM_LogicalDisk")
        Dim subclasses As ManagementObjectCollection

        subclasses = cls.GetSubclasses(opt)

        For Each subclass As ManagementClass In subclasses
            Console.WriteLine("Subclass found: {0}", _
                subclass("__CLASS"))
        Next

        Return 0
