Question

我正在尝试创建一个自定义工作流活动，它为我提供了我在列表中存储的收件人列表。但是，一旦我部署并启动工作流程，就不会发生任何事情，即使是日志消息也不会发生。所以我试图调试代码，但没有设置断点，我收到错误“断点当前不会被命中。没有为此文档加载符号。”任何人都可以帮我解决这个问题。

以下是我在创建此活动时所遵循的步骤。 1.创建了一个工作流活动库。（请附上我的代码文件）

将.dll添加到GAC
更新了web.config和WSS.actions文件。
现在我在设计师中看到了这个动作，所以我使用设计师创建了一个工作流程。
在项目上手动设置工作流程。

这里什么也没发生，甚至没有错误。如果您需要任何进一步的信息，请与我们联系。

请找到以下代码。

Answer 1

我不确定这是否会有所帮助，但您可以尝试更改代码中的以下行：

SPSecurity.RunWithElevatedPrivileges(elevatedExecuteMethod);

对此：

SPSecurity.RunWithElevatedPrivileges(delegate(){
    ExecuteMethod();
});

Answer 2

另一个黑暗的回答：

尝试将您继承的类（http://msdn.microsoft.com/en-us/library/ms173149(v=VS.80).aspx）从SequenceActivity更改为Activity（SequenceActivity继承自CompositeActivity，后者本身继承自Activity。请参阅：http://msdn.microsoft.com/en-us/library/system.workflow.activities.sequenceactivity(v=VS.90).aspx）

如果这不起作用，请尝试完全删除构造函数。你应该能够使用base（Sequence）Activity构造函数（因为你继承了类，没有实现它）

希望有帮助...

sharepoint自定义工作流活动什么都不做，甚至不记录日志消息
