.NET Framework Class Library
Parallel.CompletionCondition Property
Evaluates after any branch completes.
Assembly: System.Activities (in System.Activities.dll)
Syntax
Visual Basic
Public Property CompletionCondition As Activity(Of Boolean) Get Set
C#
public Activity<bool> CompletionCondition { get; set; }
Visual C++
public: property Activity<bool>^ CompletionCondition { Activity<bool>^ get (); void set (Activity<bool>^ value); }
F#
member CompletionCondition : Activity<bool> with get, set
Remarks
If this property evaluates to true, then the other scheduled elements in the Branches collection are canceled. If this property is not set, all Activity objects in the Branches collection execute until completion.
Examples
The following code sample demonstrates setting the CompletionCondition property of a Parallel activity. This example is from the Cancellation Handler on Compensable Activity sample.
C#
return new Parallel { // Timeout from branch causes other branch to cancel. CompletionCondition = true, Branches = { // Delay Branch new Sequence { Activities = { new WriteLine { Text = "Branch1: Body is about to Delay 2secs transferring execution to Branch2" }, new Delay { Duration = TimeSpan.FromSeconds(2) }, new WriteLine { Text = "Branch1: Body is about to complete causing Branch2 to cancel.." }, } },
