ManagementEnumeratorAttribute Class

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)
[<Sealed>]
[<AttributeUsageAttribute(AttributeTargets.Constructor|AttributeTargets.Method, AllowMultiple = false)>]
[<HostProtectionAttribute(SecurityAction.LinkDemand, MayLeakOnAbort = true)>]
type ManagementEnumeratorAttribute =  
    class 
        inherit ManagementNewInstanceAttribute 
    end

The ManagementEnumeratorAttribute type exposes the following members.

  NameDescription
Public methodManagementEnumeratorAttributeInitializes a new instance of the ManagementEnumeratorAttribute class.
Top
  NameDescription
Public propertyNameGets or sets the name of the management attribute. (Inherited from ManagementMemberAttribute.)
Public propertySchemaGets or sets a value that defines the type of output that the method that is marked with the ManagementEnumerator attribute will output.
Public propertyTypeIdWhen implemented in a derived class, gets a unique identifier for this Attribute. (Inherited from Attribute.)
Top
  NameDescription
Public methodEqualsInfrastructure. Returns a value that indicates whether this instance is equal to a specified object. (Inherited from Attribute.)
Public methodGetHashCodeReturns the hash code for this instance. (Inherited from Attribute.)
Public methodGetTypeGets the Type of the current instance. (Inherited from Object.)
Public methodIsDefaultAttributeWhen overridden in a derived class, indicates whether the value of this instance is the default value for the derived class. (Inherited from Attribute.)
Public methodMatchWhen overridden in a derived class, returns a value that indicates whether this instance equals a specified object. (Inherited from Attribute.)
Public methodToStringReturns a string that represents the current object. (Inherited from Object.)
Top
  NameDescription
Explicit interface implemetationPrivate method_Attribute.GetIDsOfNamesMaps a set of names to a corresponding set of dispatch identifiers. (Inherited from Attribute.)
Explicit interface implemetationPrivate method_Attribute.GetTypeInfoRetrieves the type information for an object, which can be used to get the type information for an interface. (Inherited from Attribute.)
Explicit interface implemetationPrivate method_Attribute.GetTypeInfoCountRetrieves the number of type information interfaces that an object provides (either 0 or 1). (Inherited from Attribute.)
Explicit interface implemetationPrivate method_Attribute.InvokeProvides access to properties and methods exposed by an object. (Inherited from Attribute.)

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.

NoteNote

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 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]);
   }
}
