ActivityDelegate Class
Represents an activity-based callback.
Assembly: System.Activities (in System.Activities.dll)
The ActivityDelegate type exposes the following members.
| 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 a hash function for a particular type. (Inherited from Object.) |
![]() | GetResultArgument | When implemented in a derived class, returns the DelegateOutArgument of the ActivityDelegate. |
![]() | GetType | Gets the Type of the current instance. (Inherited from Object.) |
![]() | MemberwiseClone | Creates a shallow copy of the current Object. (Inherited from Object.) |
![]() | OnGetRuntimeDelegateArguments | 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.
