WF4:如何设置工作流程以接收多条消息

发布于 2024-11-09 00:34:23 字数 673 浏览 0 评论 0 原文

我想要一个工作流,它可以从 MSMQ 接收多个相同的消息。

示例:

Receive: CreateWorkflow (CanCreateInstance=True)
Do Something...
Parallel (CompletionCondition=ExitParallel)
    Parallel Branch 1
        Receive: Update (CanCreateInstance=False, Use correlation)
        Process...
    Parallel Branch 2
        Receive: Finish (CanCreateInstance=False, Use correlation)
        Set ExitParallel=True

我希望我的工作流程能够接收多个更新消息。但是,在此设置中,它只能接收 1。根据 这篇 MSDN 帖子,这应该可以工作,但我从来没有让它工作过。

解决方案是在并行分支 1 中放置无限 while 循环吗?还有别的办法吗?

I want a workflow, which can receive multiple of the same message from a MSMQ.

Example:

Receive: CreateWorkflow (CanCreateInstance=True)
Do Something...
Parallel (CompletionCondition=ExitParallel)
    Parallel Branch 1
        Receive: Update (CanCreateInstance=False, Use correlation)
        Process...
    Parallel Branch 2
        Receive: Finish (CanCreateInstance=False, Use correlation)
        Set ExitParallel=True

I would like to have my workflow be able to receive multiple Update messages. However, in this setup, it can only receive 1. According to this MSDN post, this should work, but I never got this to work.

Is the solution to put an infinite while loop in Parallel Branch 1? Is there another way?

为了接收多个更新消息,您必须将接收放入循环中。您现在设置的方式允许更新一次,并且并行仅等待第二个分支(带有“完成”)完成。

In order to receive multiple update messages you will have to put that receive in a loop. The way you set it up right now the update is allowed once and the Parallel only waits for the second branch, with the Finish, to complete.
