异步调用Web服务 [英] Calling a Web service asynchronously

问题描述

我该如何异步"调用Web服务方法?是从我的WF4工作流中获取的吗?参考服务.那是一种方式.您也许还可以使用InvokeMethod活动来调用 Web服务的方法，使用您从添加服务参考"中获得的类型，并在InvokeMethod上将Async属性设置为true. (我从没做过，但是我想不出它为什么不起作用的任何原因.)

How can i call a web service method "asynchronously" from my WF4 workflow?

解决方案

You could create a custom AsyncCodeActivity based activity that makes the call using the async methods of the classes you get when you add service reference to the service. That would be one way. You also may be able to use the InvokeMethod activity to call the method of the web service using the types you get from Add Service Reference, and set the Async property to true on the InvokeMethod. (I've never done this but I can't think of any reason why it would not work).
