NativeActivity<TResult> Class
Abstract base class for custom activities that implement execution logic using the M:System.Activities.NativeActivity`1.Execute(System.Activities.ActivityExecutionContext) method, that has full access to the runtime’s features.

| Name | Description | |
|---|---|---|
![]() | NativeActivity<TResult>() | When implemented in a derived class, creates a new instance of the derived class. |
| Name | Description | |
|---|---|---|
![]() | CacheId | Gets the identifier of the cache that is unique within the scope of the workflow definition.(Inherited from Activity.) |
![]() | CanInduceIdle | Gets or sets a value that indicates whether the activity can cause the workflow to become idle. |
![]() | 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 | The execution logic of the activity.(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 | |
|---|---|---|
![]() | Abort(NativeActivityAbortContext^) | When implemented in a derived class, takes actions in response to the activity being aborted. |
![]() | CacheMetadata(ActivityMetadata) | Not implemented. Use CacheMetadata instead.(Overrides Activity::CacheMetadata(ActivityMetadata).) |
![]() | CacheMetadata(NativeActivityMetadata) | Creates and validates a description of the activity’s arguments, variables, child activities, and activity delegates. |
![]() | Cancel(NativeActivityContext^) | When implemented in a derived class, runs logic to cause graceful early completion of the activity. |
![]() | Equals(Object^) | Determines whether the specified object is equal to the current object.(Inherited from Object.) |
![]() | Execute(NativeActivityContext^) | When implemented in a derived class, runs the activity’s execution logic. |
![]() | 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(NativeActivityUpdateMapMetadata^, Activity^) | Raises an event when creating a map for the dynamic update. |
![]() | 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.) |
![]() | UpdateInstance(NativeActivityUpdateContext^) | Updates the instance of NativeActivity<TResult>. |
The following code sample demonstrates creating a class that inherits from NativeActivity<TResult>. This example is from the How to: Create an Activity step of the Getting Started Tutorial [.NET Framework 4.5].
