设置工作流程的特定指导 [英] Setting a specific guid for a workflow

问题描述

您好！

像以前的版本一样，在使用4.0实例化工作流时，是否无法指定特定的Guid作为工作流的身份?

最好的问候，

Hello!

Isn't it possible to specify a specific Guid to be the identity of the workflow when instantiating a workflow using 4.0 as it was with the earlier versions?



Best regards,

Henrik Dahl

推荐答案

您好，Henrik，

要充分利用工作流运行时的性能，可以将WorkflowInstance子类化.它具有创建GUID作为工作流ID的虚拟方法.但是，我不建议您这样做，因为编写您自己的自定义WorkflowInstance可能会涉及到很多事情.

您的情况是什么?我认为您可以使用字典"将身份(而不是覆盖现有身份)或工作流相关联，使用提升的属性将其与持久性存储相关联，并使用基于内容的关联将其与工作流服务相关联.

希望可以帮上忙，

，谢谢，
安德鲁

Hi Henrik,

  To use the full breath of the workflow runtime, you can subclass WorkflowInstance. It has a virtual method to create a GUID as the ID of the workflow. However, I won't recommend you to do this because it might be quite involved to write your own custom WorkflowInstance.

  What is your scenario? I think you can associate an identity (instead of overriding the existing identity) or a workflow by using a Dictionary, to the persistence store by using promoted properties, and to workflow services using content based correlation.

Hope that helps,

Thanks,
Andrew
