Examples

The following code sample demonstrates creating a PickBranch activity. This example is from the Using the Pick Activity sample.

static Activity CreateWF()
{
    Variable<string> name = new Variable<string>();
    Sequence body = new Sequence
    {
        Variables = { name },
        Activities =
        {
            new WriteLine { Text = "What is your name? (You have 5 seconds to answer)" },
            new Pick
            {
               Branches =
               {
                   new PickBranch
                    {
                       Trigger = new ReadString
                       {
                           Result = name,
                           BookmarkName = bookmarkName
                       },
                       Action = new WriteLine
                       {
                           Text = new InArgument<string>(env => "Hello " + name.Get(env))
                       }
                   },
                   new PickBranch
                    {
                       Trigger = new Delay
                       {
                           Duration = TimeSpan.FromSeconds(5)
                       },
                       Action = new WriteLine
                       {
                           Text = "Time is up."
                       }
                   }
               }
           }
       }
    };

    return body;
}

Remarks

A PickBranch contains a Trigger and an Action. At the beginning of a Pick element's execution, all the trigger activities from all PickBranch elements are scheduled. When the first (leftmost) activity completes, the corresponding action activity is scheduled, and all other trigger activities are canceled.
