Initializes a new instance of the EnumerationOptions class.

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. |

Initializes a new instance of the EnumerationOptions class to be used for queries or enumerations, allowing the user to specify values for the different options. |

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"]);
}
}

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

- 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.
