範例

下列程式碼範例會檢查傳遞給 WorkflowApplicationCompletedEventArgs 執行個體之 Completed 處理常式的 WorkflowApplication,並且顯示工作流程如何完成的相關資訊。The following code example inspects the WorkflowApplicationCompletedEventArgs passed into the Completed handler of a WorkflowApplication instance and displays information about how the workflow completed.

wfApp.Completed = delegate(WorkflowApplicationCompletedEventArgs e)
{
    if (e.CompletionState == ActivityInstanceState.Faulted)
    {
        Console.WriteLine("Workflow {0} Terminated.", e.InstanceId);
        Console.WriteLine("Exception: {0}\n{1}",
            e.TerminationException.GetType().FullName,
            e.TerminationException.Message);
    }
    else if (e.CompletionState == ActivityInstanceState.Canceled)
    {
        Console.WriteLine("Workflow {0} Canceled.", e.InstanceId);
    }
    else
    {
        Console.WriteLine("Workflow {0} Completed.", e.InstanceId);
