Examples

The following code sample demonstrates setting the CompletionCondition property of a Parallel activity.

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.." },
            }
        },

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.
