Gets access to property values through [] notation. This property is the indexer for the ManagementBaseObject class. You can use the default indexed properties defined by a type, but you cannot explicitly define your own. However, specifying the expando attribute on a class automatically provides a default indexed property whose type is Object and whose index type is String.

public:
 property System::Object ^ default[System::String ^] { System::Object ^ get(System::String ^ propertyName); void set(System::String ^ propertyName, System::Object ^ value); };
public object this[string propertyName] { get; set; }
member this.Item(string) : obj with get, set
Default Public Property Item(propertyName As String) As Object

Parameters

propertyName
String

The name of the property of interest.

Property Value

Object

The management object for a specific class property.

Examples

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

using System;
using System.Management;

public class Sample
{
    public static void Main()
    {
        ManagementClass c = new ManagementClass("Win32_Process");
        foreach (ManagementObject o in c.GetInstances())
            Console.WriteLine(
                "Next instance of Win32_Process : {0}", o["Name"]);
    }
}

Imports System.Management


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

        Dim c As New ManagementClass("Win32_Process")
        Dim o As ManagementObject
        For Each o In c.GetInstances()
            Console.WriteLine( _
                "Next instance of Win32_Process : {0}", o("Name"))
        Next o

    End Function
End Class
