工作流基础 4.0 使用参数加载工作流

WF 4.0 SP1

我们正在尝试加载工作流程并根据用户操作进行状态遍历。因此，当用户说批准时，我们会通过如下所示的内容：

var activity = new StateMachineApprovalFlow();
        WorkflowApplication application = new WorkflowApplication(activity);
        var approval = new Approval();
        approval.Status = ApprovalStatus.Completed;
        activity.Approval = approval;

        SetupInstanceStore();
        application.InstanceStore = store;

        application.Extensions.Add(new OracleTrackingParticipant());

        application.Load(instanceId);

这会破坏。首先这是正确的方法还是我应该使用书签。我对工作流程非常陌生，所以例子会有所帮助。

谢谢

WF 4.0 with SP1

We are trying to load workflow and do state traversal based on users actions. So say when user say approve we pass something like below:

var activity = new StateMachineApprovalFlow();
        WorkflowApplication application = new WorkflowApplication(activity);
        var approval = new Approval();
        approval.Status = ApprovalStatus.Completed;
        activity.Approval = approval;

        SetupInstanceStore();
        application.InstanceStore = store;

        application.Extensions.Add(new OracleTrackingParticipant());

        application.Load(instanceId);

This breaks.First is this the right way or should i use bookmark. i am very new to workflow so example will help.

Thanks

首先，您需要创建一个创建书签的活动。然后，您必须运行工作流，直到它空闲下来等待该书签。

然后，您按照已完成的方式加载工作流程，并按照

var result = application.ResumeBookmark(bookmarkName, data);

一定要检查结果以确保其恢复正常。 Microsoft.Activities（在 CodePlex 上提供）有一些扩展方法可以使这变得更容易。有关示例，请参阅Microsoft.Activities.UnitTesting - 如何使用书签测试活动？

First you need to create an activity which creates a bookmark. Then you must run the workflow until it becomes idle waiting for that bookmark.

Then, you load the workflow as you have done and follow that by

var result = application.ResumeBookmark(bookmarkName, data);

Be sure to check the result to see that it resumed ok. Microsoft.Activities (available on CodePlex) has some extension methods to make this easier as well. For a sample see Microsoft.Activities.UnitTesting - How do I test an activity with bookmarks?
