项目批准 [英] Item Approval

问题描述

您好，

我需要将工作流程应用于现有的.Net C＃Web窗体应用程序。任何人都可以指向一个功能齐全的示例吗？

I need to apply a workflow to an existing .Net C# Web Forms application. Can anyone point me in the direction of a fully functional example?

我不确定我是否需要顺序或状态机。总之，这就是我需要工作流程来做的事情：

I'm not sure whether I need sequential or state machine. In summary this is what I need the workflow to do:

-  新项目通过网络表单添加到数据库表中$
- 然后给协调员发电子邮件

- 协调员然后分配其他用户

- 他们收到电子邮件

- 他们提供回复（如果不是那么工作流程）需要发送提醒电子邮件）

- 协调员可以随时完成/完成工作流程

- a new item gets added to a database table via a web form
- this then emails a coordinator
- the coordinator then assigns other users
- they get emailed
- they provide a response (if not then the workflow needs to send them reminder emails)
- the coordinator can complete / finish the workflow at any time

谢谢

推荐答案

您可以使用顺序或状态机来执行此操作。既然你要为其他用户分配一个任务（并行？，它会向几个用户发送，然后等待，并向这些人发送提醒）顺序工作流程会更简单一点（你可以等待多个用户到
）在状态机中提交任务但在顺序工作流程中更容易。

You could do this with a sequential or a state machine. Since you are assigning other users a task (in parallel?, it goes out to several users and then waits, and sends reminders to these folks) a Sequential workflow would be a little simpler (you could wait for multiple users to submit a task in a state machine but it is easier in a Sequential workflow.

我不知道完整的函数示例，它说明了所有这些部分。

I don't know of a fully functionl sample that illustrates all these parts though.

那么工作流程是从Web表单开始的吗？它将一个新项目添加到数据库表中，然后启动工作流程？

So the workflow is kicked off from the web form? It adds a new item to a database table and then starts the workflow?

工作流程可以使用自定义活动给协调员发电子邮件。（ SendMail自定义活动样本）

The workflow could use a custom activity to email the coordinator. (SendMail custom activity sample)

协调员可以分配用户，并通过基于事件的活动将此用户列表分发到工作流程中（工作流程/主机通信）

The coordinator could assign users, and dispatch this list of users to the workflow via an event based activity (workflow/host communications)

主机可以使用
复制器活动为每个用户执行以下操作：发送电子邮件，让他们知道他们的输入是需要，等待回复。您可以使用
听取活动（或$ b） $ b EventDriven活动）等待回复或超时间隔可以发送电子邮件以提醒他们需要输入。

The host could use a replicator activity to perform the following for each user: Send an email letting them know that their input is needed, and wait for the reply. You can use a Listen Activity (or an EventDriven activity) to wait for either the reply or a timeout interval that could send an email to remind them that their input is needed.

侦听用户批准的部分可以进入
ConditionedActivityGroup ，如果协调员希望在所有批准之前完成工作流程，则可以取消所有这些。

The part that listens for the user approvals could go into a ConditionedActivityGroup, which coould cancel all of that if the coordinator wishes to complete the workflow before all approvals are in.

如果你不依赖于.NET 3.5 Work流，有一个较新的.NET 4工作流，如下所述：

If you are not tied to .NET 3.5 Workflow, there is a newer .NET 4 Workflow, described here: http://msdn.microsoft.com/en-us/netframework/first-steps-with-wf.aspx#content4

请回复返回更多信息，我可以深入了解更多细节。
