Im folgenden Codebeispiel wird das Festlegen der Trigger-Eigenschaft einer PickBranch-Aktivität gezeigt. Dieses Beispiel stammt aus dem Beispiel Verwenden der Pick-Aktivität .

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;
}
