如何恢复：工作流设计器遇到的问题与您的文档 [英] How to recover from : Workflow Designer encountered problems with your document

问题描述

与工作流的新手我创建工作流（VS2010中的工作流设计器）与中，我有一个WriteLine活动的序列。我与工作流创建参数，以便我在参数窗格中创建2个参数W / O的活动水平与做他们什么实验。 （值得注意的是，我没有对如何在工作流中使用参数的把握还）。不过，我救我的工作流，而工作流不显示任何可见的错误（红色圆圈与excalmation标记）。下一次我打开我的工作流程得到错误：

As a novice with workflows I create a workflow (in VS2010 workflow designer) with a sequence within which I have a writeline activity. I am experimenting with creating arguments for the workflow so I create 2 arguments in the argument pane w/o doing anything with them at the activity level. (Noteworthy that I dont have a grasp of how to use arguments in the workflow yet). However I save my workflow while the workflow does not show any visible errors( red circles with an excalmation mark). Next time I open the workflow I get the error :

工作流设计器遇到了你的文件的问题。
请检查该文件无效内容，命名空间，引用或参考循环。

Workflow Designer encountered problems with your document . Please check the document for invalid content, namespaces,references, or reference loops.

这似乎使最终因为没有办法，我可以有机会获得我原来的工作流程，可能纠正我的错误（无论它们是什么）。当我点击详细向下箭头我看到这一点：找不到成员'A'的_8684类型。

And that seems so final because there is no way that I can have access to my original workflow to possibly correct my error (whatever they might be). when I click on the detail down arrow I see this: Could not find member 'a' in type _8684 .

一个是两个INT32论点，我不得不在工作流，但我从来没有在任何活动中的一个。

a is one of the two int32 arguments that I had in the workflow but which I never used in any of the activities.

我想AP preciate任何帮助。先谢谢了。

I would appreciate any help. Thanks in advance.

推荐答案

看来你要重新托管的工作流设计，它不是为你生成正确的XAML。

It seems you're trying to re-host your Workflow Designer and it's not generating correct XAML for you.

错误找不到成员＆LT; MNAME＆GT;在类型＆lt;＆TNAME GT; 如果工作流设计实例直接载入容器活动（顺序，流程图等），而不是第一个使用ActivityBuilder通常发生

The error Could not find member <mname> in type <tname> commonly occurs if the Workflow Designer instance is directly loading a container activity (sequence, flowchart etc.) instead of using an ActivityBuilder first.

如果您已经使用了ActivityBuilder，那么你可能已经错过了给它的根系活力空间。 。正确的方式来增加 System.Activities presentation.WorkflowDesigner 是：

If you're already using an ActivityBuilder then you may have missed giving it the root activity namespace. The correct way to add System.Activities.Presentation.WorkflowDesigner is:

this.workflowDesigner = new WorkflowDesigner();
this.workflowDesigner.Load(new ActivityBuilder { Implementation = new Sequence(),
                                                 Name = "RootNamespace.RootActivity" });

随着名称设置不当WF设计师会（像你的情况_8684）停止使用随机类型和生成保存/序列正确的XAML。这会帮助你摆脱空间的错误。

With the Name set properly WF designer would stop using random types (like _8684 in your case) and generate correct XAML on save/serialization. This should help you get rid of the namespace errors.
