AsyncCodeActivity<TResult> Class
Manages asynchronous code activity execution, for an activity of a specified type, from start to completion. This is an abstract and generic class.
Assembly: System.Activities (in System.Activities.dll)

| Name | Description | |
|---|---|---|
![]() | AsyncCodeActivity<TResult>() | Creates a new instance of the AsyncCodeActivity class. |
| Name | Description | |
|---|---|---|
![]() | CacheId | Gets the identifier of the cache that is unique within the scope of the workflow definition.(Inherited from Activity.) |
![]() | Constraints | Gets a collection of Constraint activities that can be configured to provide validation for the Activity.(Inherited from Activity.) |
![]() | DisplayName | Gets or sets an optional friendly name that is used for debugging, validation, exception handling, and tracking.(Inherited from Activity.) |
![]() | Id | Gets an identifier that is unique in the scope of the workflow definition.(Inherited from Activity.) |
![]() | Implementation | Gets null or throws an error when there is an attempt to set the value of this property.(Overrides Activity::Implementation.) |
![]() | ImplementationVersion | Gets or sets the implementation version of the activity.(Overrides Activity::ImplementationVersion.) |
![]() | Result | Gets or sets the result argument for the Activity<TResult>.(Inherited from Activity<TResult>.) |
![]() | ResultType | When implemented in a derived class, gets the type of an activity OutArgument.(Inherited from ActivityWithResult.) |
| Name | Description | |
|---|---|---|
![]() | BeginExecute(AsyncCodeActivityContext^, AsyncCallback^, Object^) | When implemented in a derived class and using the specified execution context, callback method, and user state, enqueues an asynchronous activity in a run-time workflow. |
![]() | CacheMetadata(ActivityMetadata) | Not implemented. Use CacheMetadata instead.(Overrides Activity::CacheMetadata(ActivityMetadata).) |
![]() | CacheMetadata(CodeActivityMetadata) | Serves as a virtual method and converts information obtained by reflection on a cache into arguments for an asynchronous activity. |
![]() | Cancel(AsyncCodeActivityContext^) | When implemented in a derived class and using the specified execution environment information, notifies the workflow runtime that the asynchronous activity operation has been canceled. This method serves as a virtual method. |
![]() | EndExecute(AsyncCodeActivityContext^, IAsyncResult^) | When implemented in a derived class and using the specified execution environment information, notifies the workflow runtime that the associated asynchronous activity operation has completed. |
![]() | Equals(Object^) | Determines whether the specified object is equal to the current object.(Inherited from Object.) |
![]() | Finalize() | Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection.(Inherited from Object.) |
![]() | GetHashCode() | Serves as the default hash function. (Inherited from Object.) |
![]() | GetType() | |
![]() | MemberwiseClone() | |
![]() | OnCreateDynamicUpdateMap(UpdateMapMetadata^, Activity^) | Raises an event when creating a map for the dynamic update.(Overrides Activity::OnCreateDynamicUpdateMap(UpdateMapMetadata^, Activity^).) |
![]() | ShouldSerializeDisplayName() | Indicates whether the DisplayName property should be serialized.(Inherited from Activity.) |
![]() | ToString() | Returns a String that contains the Id and DisplayName of the Activity.(Inherited from Activity.) |
