Question

我有一个具有两种状态的状态机工作流程 - 员工要求 - 经理批准

在Employee请求中，我通过代码活动和genereate将请求保存到数据库请求编号

在调用WorkflowApplication.Run（）

之后如何获得这些输出

Answer 1

您需要设置WorkflowApplication操作的回调：

WorkflowApplication Application;
//...
// Setup callbacks
this.Application.Completed += OnApplicationCompleted;
// Run the application
this.Application.Run();

然后像这样实现OnApplicationCompleted：

void OnApplicationCompleted(WorkflowApplicationCompletedEventArgs e)
{
    switch (e.CompletionState)
    {
        case ActivityInstanceState.Closed:
            // Application finished correctly
            // Get outputs
            var output1 = e.Outputs["NameOfOutput"];
            break;

        case ActivityInstanceState.Canceled:
            // Application was cancelled before completion
            break;

        case ActivityInstanceState.Faulted:
            // Application throw an exception and was shut down
            break;
    }
}
