c# - 以编程方式列出项目多个用户权限(共享点)

Question

我环顾四周，还没有找到解决方案。我到处拾取代码片段来寻找解决方案。

我有一个名为“文档协作”的文档库，其中包含“分配给”字段。这是人员/组字段。这些人将能够处理特定文档(列表项权限)。现在，首先，他们将具有隐藏权限(他们看不到它)，但是当添加到文档时，他们将看到它并能够贡献它，他们还将收到电子邮件通知。我在下面附上了完整的代码。

所以，当我进行 VS10 调试时，我没有收到任何错误。但它不发送任何电子邮件或不设置权限。怎么了？

Answer 1

不，我犯了一个简单的错误，将其置于检查状态而不是更新状态，还有一个解决方法是在更新时多次运行该函数，只需在列表中创建一个名为“updateContributors”的列并使用默认值正确/是

这是代码/没有时间解释，但评论很好，祝你好运:
