在工作流程中实现多线程
我知道单个工作流实例一次在单个线程中运行。我有一个工作流程，其中一个选择活动中有两个接收活动。实现消息关联是为了确保对两个活动的请求应路由到同一实例。
在第一个接收分支中，我有一个并行活动，其中一个分支中有一个延迟活动。并行活动将在延迟结束或标志设置为 true 时完成。
当并行活动等待条件满足时，我如何接收来自第二个接收活动的调用？因为该标志只有通过它的分支才会被设置为 true。我正在等待您的建议或想法。
I'm aware a single workflow instance run in a single thread at a time. I've a workflow with two receive activities inside a pick activity. Message correlation is implemented to make sure the requests to both the activities should be routed to the same instance.
In the first receive branch I've a parallel activity with a delay activity in one branch. The parallel activity will complete either the delay is over or a flag is set to true.
When the parallel activity is waiting for the condition to meet how I can receive calls from the second receive activity? because the flag will be set to true only through through it's branch. I'm waiting for your suggestions or ideas.

不太确定你想在这里实现什么目标。
如果您有一个具有 2 个分支的 Pick，并且两个分支都包含一个 Receive，则在您收到 2 个 Receive 活动正在等待的 2 条消息中的一条消息后，它将继续。另一个将被取消并且不会收到任何东西。一个接收是并行的这一事实在这里不会产生影响。因此，除非这是一个循环，否则您在工作流中不会收到多于一条 WCF 消息。
Not quite sure what you are trying to achieve here.
If you have a Pick with 2 branched and both branches contain a Receive it will continue after you receive either of the 2 messages the 2 Receive activities are waiting for. The other will be canceled and not receive anything. The fact that one Receive is in a Parallel will not make a difference here. So unless this is on a loop you will not receive more than one WCF message in your workflow.
