ManagementEnumeratorAttribute Class

 

The ManagementEnumerator attribute marks a method that returns all the instances of a WMI class.

Note: the WMI .NET libraries are now considered in final state, and no further development, enhancements, or updates will be available for non-security related issues affecting these libraries. The MI APIs should be used for all new development.

public sealed class ManagementEnumeratorAttribute : ManagementNewInstanceAttribute

NameDescription
System_CAPS_pubpropertyName

Gets or sets the name of the management attribute.(Inherited from ManagementMemberAttribute.)

System_CAPS_pubpropertySchema

Gets or sets a value that defines the type of output that the method that is marked with the ManagementEnumerator attribute will output.

System_CAPS_pubpropertyTypeId

When implemented in a derived class, gets a unique identifier for this Attribute.(Inherited from Attribute.)

NameDescription
System_CAPS_pubmethodEquals(Object)

This API supports the product infrastructure and is not intended to be used directly from your code. Returns a value that indicates whether this instance is equal to a specified object.(Inherited from Attribute.)

System_CAPS_pubmethodGetHashCode()

Returns the hash code for this instance.(Inherited from Attribute.)

System_CAPS_pubmethodGetType()

Gets the Type of the current instance.(Inherited from Object.)

System_CAPS_pubmethodIsDefaultAttribute()

When overridden in a derived class, indicates whether the value of this instance is the default value for the derived class.(Inherited from Attribute.)

System_CAPS_pubmethodMatch(Object)

When overridden in a derived class, returns a value that indicates whether this instance equals a specified object.(Inherited from Attribute.)

System_CAPS_pubmethodToString()

Returns a string that represents the current object.(Inherited from Object.)

NameDescription
System_CAPS_pubinterfaceSystem_CAPS_privmethod_Attribute.GetIDsOfNames(Guid, IntPtr, UInt32, UInt32, IntPtr)

Maps a set of names to a corresponding set of dispatch identifiers.(Inherited from Attribute.)

System_CAPS_pubinterfaceSystem_CAPS_privmethod_Attribute.GetTypeInfo(UInt32, UInt32, IntPtr)

Retrieves the type information for an object, which can be used to get the type information for an interface.(Inherited from Attribute.)

System_CAPS_pubinterfaceSystem_CAPS_privmethod_Attribute.GetTypeInfoCount(UInt32)

Retrieves the number of type information interfaces that an object provides (either 0 or 1).(Inherited from Attribute.)

System_CAPS_pubinterfaceSystem_CAPS_privmethod_Attribute.Invoke(UInt32, Guid, UInt32, Int16, IntPtr, IntPtr, IntPtr, IntPtr)

Provides 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.

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.
