[英]“Suspend” a workflow in .NET 4?

原文 2011-04-13 05:55:29 9 1 .net/ workflow/ workflow-foundation/ workflow-foundation-4/ suspend

I've to do a small test application, I want to suspend the application. 我必须做一个小型测试应用程序，我想暂停该应用程序。

I saw there is a "SuspendActivity" but I can't find it in .Net 4.0, so how I'm supposed to pause my workflow and resume it from my application? 我看到有一个“ SuspendActivity”，但在.Net 4.0中找不到，所以应该如何暂停工作流程并从应用程序中恢复它？

It's for a single sample on which I've to display every step with a "next" button. 它是针对单个样本的，我必须在该样本上使用“下一步”按钮显示每个步骤。

Thank you very much! 非常感谢你！

I think that you are looking for the new Bookmarks concept in WF 4.0. 我认为您正在寻找WF 4.0中的新“ 书签”概念。 Basically, you can create a custom activity that defines a bookmark, and when the workflow execution reaches this activity, the execution is suspended until you resume the bookmark. 基本上，您可以创建一个定义书签的自定义活动，当工作流程执行到该活动时，该执行将被挂起，直到您恢复书签为止。

Take a look into the section Additional activity concepts in A Developer's Introduction to Windows Workflow Foundation (WF) in .NET 4 查看“ .NET 4中开发人员对Windows Workflow Foundation（WF）的介绍”中的“ 其他活动概念 ”部分。

It is a very good introuduction to WF 4.0. 这是对WF 4.0的很好的介绍。 Hope it helps! 希望能帮助到你！
