Gets or sets a value indicating whether direct access to the WMI provider is requested for the specified class, without any regard to its super class or derived classes.
public:
property bool DirectRead { bool get(); void set(bool value); };public bool DirectRead { get; set; }member this.DirectRead : bool with get, setPublic Property DirectRead As Booleantrue if direct access to the WMI provider is requested for the specified class; otherwise, false.
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
true if only objects of the specified class should be received, without regard to derivation or inheritance; otherwise, false. The default value is false.
