示例1: OnWorkflowIdled
static void OnWorkflowIdled(object sender, WorkflowEventArgs e)
{
WorkflowInstance workflow = e.WorkflowInstance;
Console.WriteLine("\n...waiting for 3 seconds... \n");
Thread.Sleep(3000);
// what activity is blocking the workflow
ReadOnlyCollection<WorkflowQueueInfo> wqi = workflow.GetWorkflowQueueData();
foreach (WorkflowQueueInfo q in wqi)
{
EventQueueName eq = q.QueueName as EventQueueName;
if (eq != null)
{
// get activity that is waiting for event
ReadOnlyCollection<string> blockedActivity = q.SubscribedActivityNames;
Console.WriteLine("Host: Workflow is blocked on " + blockedActivity[0]);
// this event is never going to arrive eg. employee left the company
// lets send an exception to this queue
// it will either be handled by exception handler that was modeled in workflow
// or the runtime will unwind running compensation handlers and exit the workflow
Console.WriteLine("Host: This event is not going to arrive");
Console.WriteLine("Host: Cancel workflow with unhandled exception");
workflow.EnqueueItem(q.QueueName, new Exception("ExitWorkflowException"), null, null);
}
