AsyncCodeActivity<TResult> Class

Definition

Namespace:

System.Activities

Assembly:

System.Activities.dll

Manages asynchronous code activity execution, for an activity of a specified type, from start to completion. This is an abstract and generic class.

generic <typename TResult>
public ref class AsyncCodeActivity abstract : System::Activities::Activity<TResult>

public abstract class AsyncCodeActivity<TResult> : System.Activities.Activity<TResult>

type AsyncCodeActivity<'Result> = class
    inherit Activity<'Result>

Public MustInherit Class AsyncCodeActivity(Of TResult)
Inherits Activity(Of TResult)

Type Parameters

TResult

The type of the asynchronous activity that is handled by this class.

Constructors

AsyncCodeActivity<TResult>()

Creates a new instance of the AsyncCodeActivity class.

Properties

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.
ImplementationVersion	Gets or sets the implementation version of the activity.
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)

Methods

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(CodeActivityMetadata) instead.
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)
GetHashCode()	Serves as the default hash function. (Inherited from Object)
GetType()	Gets the Type of the current instance. (Inherited from Object)
MemberwiseClone()	Creates a shallow copy of the current Object. (Inherited from Object)
OnCreateDynamicUpdateMap(UpdateMapMetadata, Activity)	Raises an event when creating a map for the dynamic update.
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)
