The ManagementEnumerator attribute marks a method that returns all the instances of a WMI class.
Namespace:
System.Management.Instrumentation
Assembly:
System.Core (in System.Core.dll)
Visual Basic (Declaration)
<AttributeUsageAttribute(AttributeTargets.Constructor Or AttributeTargets.Method, AllowMultiple := False)> _
<HostProtectionAttribute(SecurityAction.LinkDemand, MayLeakOnAbort := True)> _
Public NotInheritable Class ManagementEnumeratorAttribute _
Inherits ManagementNewInstanceAttribute
Dim instance As ManagementEnumeratorAttribute
[AttributeUsageAttribute(AttributeTargets.Constructor|AttributeTargets.Method, AllowMultiple = false)]
[HostProtectionAttribute(SecurityAction.LinkDemand, MayLeakOnAbort = true)]
public sealed class ManagementEnumeratorAttribute : ManagementNewInstanceAttribute
[AttributeUsageAttribute(AttributeTargets::Constructor|AttributeTargets::Method, AllowMultiple = false)]
[HostProtectionAttribute(SecurityAction::LinkDemand, MayLeakOnAbort = true)]
public ref class ManagementEnumeratorAttribute sealed : public ManagementNewInstanceAttribute
public final class ManagementEnumeratorAttribute extends ManagementNewInstanceAttribute
The method must be static and public. It must return a collection of all instances of the WMI class. The collection can be of any type convertible to IEnumerable.
The following example shows how to use the Enumerator attribute to mark a method that is used to enumerate instances of a class. In this case, the Enumerate method uses the Process class to retrieve all of the processes running on the computer.
[C#]
[ManagementEnumerator]
public static IEnumerable Enumerate()
{
Process[] rgProcesses = Process.GetProcesses();
for (int i = 0; i < rgProcesses.Length; i++)
{
yield return new ProcessProvider(rgProcesses[i]);
}
}

Any public static (Shared in Visual Basic) members of this type are thread safe. Any instance members are not guaranteed to be thread safe.
