| Name | Description | |
|---|---|---|
![]() | ActivityDelegate() | Called by derived class constructors to initialize the object. |
| Name | Description | |
|---|---|---|
![]() | DisplayName | Gets or sets an optional friendly name that is used for debugging, validation, exception handling, and tracking. |
![]() | Handler | Gets or sets the activity that is represented by this ActivityDelegate. |
| Name | Description | |
|---|---|---|
![]() | 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.) |
![]() | GetResultArgument() | When implemented in a derived class, returns the DelegateOutArgument of the ActivityDelegate. |
![]() | GetType() | |
![]() | MemberwiseClone() | |
![]() | OnGetRuntimeDelegateArguments(IList<RuntimeDelegateArgument^>^) | Supplies a list of runtime arguments for the ActivityDelegate. |
![]() | ShouldSerializeDisplayName() | Indicates whether the DisplayName property value should be serialized to XAML. |
![]() | ToString() | Returns a String representation of the ActivityDelegate that contains the DisplayName.(Overrides Object::ToString().) |
Activity delegates enable activity authors to expose callbacks with specific signatures that users of the activity can provide activity-based handlers for. There are two types of activity delegates: ActivityAction<T> is used for invoking activities that do not have a return value, and ActivityFunc<TResult> is used for invoking activities that do have a return value. Activity delegates are useful in scenarios where a child activity must be constrained to having a certain signature.
