以编程方式列出项目多个用户的权限(共享点) [英] List Item multiple users permissions programmatically (sharepoint)
问题描述
我已经环顾四周，还没有找到解决方案.我在这里和那里拾起了代码片段以找到解决方案.
I've looked around and haven't found a solution yet. I have picked up code snippets here and there to find a solution.
我有一个名为文档协作"的文档库，其字段为分配给".这是一个人员/组"字段.这些人将能够处理特定的文档(列表项权限).现在，起初，他们将具有隐藏的权限(他们看不到)，但是将其添加到文档中后，他们将看到它并能够对其进行贡献，并且还将收到电子邮件通知.我已经附上了完整的代码.
I have a Doc Library called "Document Collaboration" with the field "Assigned To". This is a People/Groups field. These people will be able to work on a specific document(list item permission). Now, at first, they will have hidden permissions(they cant see it), but when added to the doc, they will see it and be able to contribute it, also they will get an email notification. I have attached the full code below.
因此，当我进行VS10调试时，没有任何错误.但是它不会发送任何电子邮件或未设置权限.怎么了?
So, I don't get any errors, when I go through VS10 debug. But it doesn't send any email or doesn't set the permissions. What's wrong?

推荐答案
不，我犯了一个简单的错误，将其置于签入状态而不是更新状态，该函数在更新时多次运行也存在变通办法，只需在列表中添加一个名为"updateContributors"的列，并使用默认值True/Yes
nope, I made the simple mistake of putting it under checked in instead of updated, there's also a work around for the function being run multiple times when it updates, just make a column called "updateContributors" in your list and default value True/Yes
