CoreTaskExtensionsSelect Method (Task, ActionTask, Boolean) |
Synchronously execute a continuation when a task completes. The supportsErrors
parameter specifies whether the continuation is executed if the antecedent task is faulted.
Namespace: net.openstack.CoreAssembly: openstacknet (in openstacknet.dll) Version: 1.7.7+Branch.master.Sha.25d803f397c8693c2c13777ef6675f796f520f2c
Syntax public static Task Select(
this Task task,
Action<Task> continuationAction,
bool supportsErrors
)
<ExtensionAttribute>
Public Shared Function Select (
task As Task,
continuationAction As Action(Of Task),
supportsErrors As Boolean
) As Task
public:
[ExtensionAttribute]
static Task^ Select(
Task^ task,
Action<Task^>^ continuationAction,
bool supportsErrors
)
[<ExtensionAttribute>]
static member Select :
task : Task *
continuationAction : Action<Task> *
supportsErrors : bool -> Task
Parameters
- task
- Type: System.Threading.TasksTask
The antecedent task. - continuationAction
- Type: SystemActionTask
The continuation action to execute when task completes. - supportsErrors
- Type: SystemBoolean
if the continuationAction properly handles a faulted antecedent task; otherwise, .
Return Value
Type:
TaskA
Task representing the asynchronous operation.
Usage Note
In Visual Basic and C#, you can call this method as an instance method on any object of type
Task. When you use instance method syntax to call this method, omit the first parameter. For more information, see
Extension Methods (Visual Basic) or
Extension Methods (C# Programming Guide).
Exceptions Remarks If the antecedent task is cancelled, or faulted with supportsErrors
set to , the status of the antecedent is directly applied to the task
returned by this method; it is not wrapped in an additional AggregateException.
Notes to Callers |
---|
Since the continuation is executed synchronously, this method should only be used for
lightweight continuation actions. For non-trivial continuation actions, use a
Task for the continuation operation and call
Then(Task, FuncTask, Task, Boolean) instead.
