EnumerationOptions()

Initializes a new instance of the EnumerationOptions class with default values (see the individual property descriptions for what the default values are). This is the parameterless constructor.

EnumerationOptions();public EnumerationOptions ();Public Sub New ()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();
// 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
' 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

EnumerationOptions(ManagementNamedValueCollection, TimeSpan, Int32, Boolean, Boolean, Boolean, Boolean, Boolean, Boolean, Boolean)

EnumerationOptions(System::Management::ManagementNamedValueCollection ^ context, TimeSpan timeout, int blockSize, bool rewindable, bool returnImmediatley, bool useAmendedQualifiers, bool ensureLocatable, bool prototypeOnly, bool directRead, bool enumerateDeep);public EnumerationOptions (System.Management.ManagementNamedValueCollection context, TimeSpan timeout, int blockSize, bool rewindable, bool returnImmediatley, bool useAmendedQualifiers, bool ensureLocatable, bool prototypeOnly, bool directRead, bool enumerateDeep);new System.Management.EnumerationOptions : System.Management.ManagementNamedValueCollection * TimeSpan * int * bool * bool * bool * bool * bool * bool * bool -> System.Management.EnumerationOptionsPublic Sub New (context As ManagementNamedValueCollection, timeout As TimeSpan, blockSize As Integer, rewindable As Boolean, returnImmediatley As Boolean, useAmendedQualifiers As Boolean, ensureLocatable As Boolean, prototypeOnly As Boolean, directRead As Boolean, enumerateDeep As Boolean)Parameters
- context
- ManagementNamedValueCollection
The options context object containing provider-specific information that can be passed through to the provider.
- timeout
- TimeSpan
The time-out value for enumerating through the results.
- blockSize
- Int32
The number of items to retrieve at one time from WMI.
- rewindable
- Boolean
true to show that the result set is rewindable (allows multiple traversal); otherwise, false.
- returnImmediatley
- Boolean
true to show that the operation should return immediately (semi-sync) or block until all results are available; otherwise, false.
- useAmendedQualifiers
- Boolean
true to show that the returned objects should contain amended (locale-aware) qualifiers; otherwise, false.
- ensureLocatable
- Boolean
true to ensure all returned objects have valid paths; otherwise, false.
- prototypeOnly
- Boolean
true to return a prototype of the result set instead of the actual results; otherwise, false.
- directRead
- Boolean
true to retrieve objects of only the specified class or from derived classes as well; otherwise, false.
- enumerateDeep
- Boolean
true to use recursive enumeration in subclasses; otherwise, false.

1, true, true, false,
true, false, false, true);
ManagementClass c = new ManagementClass("CIM_Service");
