AsyncCodeActivity<TResult> Class

.NET Framework (current version)
 

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

Namespace:   System.Activities

public abstract class AsyncCodeActivity<TResult> : Activity<TResult>

Type Parameters

TResult

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

NameDescription
System_CAPS_protmethodAsyncCodeActivity<TResult>()

Creates a new instance of the AsyncCodeActivity class.

NameDescription
System_CAPS_protpropertyCacheId

Gets the identifier of the cache that is unique within the scope of the workflow definition.(Inherited from Activity.)

System_CAPS_protpropertyConstraints

Gets a collection of Constraint activities that can be configured to provide validation for the Activity.(Inherited from Activity.)

System_CAPS_pubpropertyDisplayName

Gets or sets an optional friendly name that is used for debugging, validation, exception handling, and tracking.(Inherited from Activity.)

System_CAPS_pubpropertyId

Gets an identifier that is unique in the scope of the workflow definition.(Inherited from Activity.)

System_CAPS_protpropertyImplementation

Gets null or throws an error when there is an attempt to set the value of this property.(Overrides Activity.Implementation.)

System_CAPS_protpropertyImplementationVersion

Gets or sets the implementation version of the activity.(Overrides Activity.ImplementationVersion.)

System_CAPS_pubpropertyResult

Gets or sets the result argument for the Activity<TResult>.(Inherited from Activity<TResult>.)

System_CAPS_pubpropertyResultType

When implemented in a derived class, gets the type of an activity OutArgument.(Inherited from ActivityWithResult.)

NameDescription
System_CAPS_protmethodBeginExecute(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.

System_CAPS_protmethodCacheMetadata(ActivityMetadata)

Not implemented. Use CacheMetadata instead.(Overrides Activity.CacheMetadata(ActivityMetadata).)

System_CAPS_protmethodCacheMetadata(CodeActivityMetadata)

Serves as a virtual method and converts information obtained by reflection on a cache into arguments for an asynchronous activity.

System_CAPS_protmethodCancel(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.

System_CAPS_protmethodEndExecute(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.

System_CAPS_pubmethodEquals(Object)

Determines whether the specified object is equal to the current object.(Inherited from Object.)

System_CAPS_protmethodFinalize()

Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection.(Inherited from Object.)

System_CAPS_pubmethodGetHashCode()

Serves as the default hash function. (Inherited from Object.)

System_CAPS_pubmethodGetType()

Gets the Type of the current instance.(Inherited from Object.)

System_CAPS_protmethodMemberwiseClone()

Creates a shallow copy of the current Object.(Inherited from Object.)

System_CAPS_protmethodOnCreateDynamicUpdateMap(UpdateMapMetadata, Activity)

Raises an event when creating a map for the dynamic update.(Overrides Activity.OnCreateDynamicUpdateMap(UpdateMapMetadata, Activity).)

System_CAPS_pubmethodShouldSerializeDisplayName()

Indicates whether the DisplayName property should be serialized.(Inherited from Activity.)

System_CAPS_pubmethodToString()

Returns a String that contains the Id and DisplayName of the Activity.(Inherited from Activity.)
