public:
 System::Management::ManagementObjectCollection ^ GetSubclasses();

public System.Management.ManagementObjectCollection GetSubclasses ();

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

Public Function GetSubclasses () As ManagementObjectCollection

傳回

ManagementObject 物件的集合，表示 WMI 類別的子類別。

範例

下列範例會 GetSubclasses 使用 方法來將子類別列出至 CIM_LogicalDisk 類別。 如需詳細資訊，請參閱 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))
            {
                Console.WriteLine(
                    "{0} is related to " + c.ClassPath.ClassName,
                    related.ClassPath.ClassName);
            }
        }

        return;
    }
}

Imports System.Management

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

        Dim c As ManagementClass
        c = New ManagementClass("CIM_LogicalDisk")

        For Each r As ManagementClass In c.GetSubclasses()

            Console.WriteLine( _
                "Instances of {0} are sub-classes", _
                r("__CLASS"))

參數

傳回

ManagementObject 物件的集合，表示 WMI 類別的子類別 (根據指定的選項)。

範例

下列範例示範如何使用建ManagementClass構函式初始化ManagementClass變數，然後接收傳入建構函式之WMI 類別的子類別。

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
    End Function
End Class
