ManagementEnumeratorAttribute Class
The ManagementEnumerator attribute marks a method that returns all the instances of a WMI class.
Assembly: System.Core (in System.Core.dll)
'Declaration <AttributeUsageAttribute(AttributeTargets.Constructor Or AttributeTargets.Method, AllowMultiple := False)> _ <HostProtectionAttribute(SecurityAction.LinkDemand, MayLeakOnAbort := True)> _ Public NotInheritable Class ManagementEnumeratorAttribute _ Inherits ManagementNewInstanceAttribute 'Usage Dim instance As ManagementEnumeratorAttribute

The HostProtectionAttribute attribute applied to this type or member has the following Resources property value: MayLeakOnAbort. The HostProtectionAttribute does not affect desktop applications (which are typically started by double-clicking an icon, typing a command, or entering a URL in a browser). For more information, see the HostProtectionAttribute class or SQL Server Programming and Host Protection Attributes. |
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]);
}
}
