ManagementTaskAttribute Class


The .NET API Reference documentation has a new home. Visit the .NET API Browser on to see the new experience.

The ManagementTask attribute indicates that the target method implements a WMI method.

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.

[<AttributeUsageAttribute(AttributeTargets.Method, AllowMultiple = false)>]

type ManagementTaskAttribute = 
        inherit ManagementMemberAttribute


Initializes a new instance of the T:System.Management.ManagementTaskAttribute class. This is the default constructor.


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


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


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


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.)


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


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


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


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


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

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.)


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.)

By default, the WMI method name will be the name of the target method. The parent class of this attribute, ManagementMemberAttribute, includes a Name parameter. You can use that parameter to change the name of the method that is exposed through WMI without changing your internal method name.

The method must be public and it may be static. It can include any combination of [in], [out], [in/out], array or object reference parameters. Array parameters cannot be multidimensional or jagged because of limitations imposed by WMI.

The return type of the method can be: void, scalar, string, datetime or object. It cannot be an array.

The following example shows how to mark a method with the ManagementTask attribute to expose the method to WMI. The method will show up in WMI as ResetCounters.


// Use the ManagementTask attribute to specify that a method
// is exposed to WMI through this provider. Consumers will be
// able to execute this method through WMI.
public void ResetCounters()
