How to raise a 401 (Unauthorized access) exception in Sharepoint?
提问by pistacchio
As the title said, I need to raise (from the C# code behind a custom SharePoint page) a 401 error page. Any help?
正如标题所说，我需要（从自定义 SharePoint 页面背后的 C# 代码）引发 401 错误页面。有什么帮助吗？

Try this:
尝试这个：
throw new HttpException(401, "Unauthorized access");
回答by Wout
If the exception is SharePoint related it's best to throw a SharePoint exception
如果异常与 SharePoint 相关，则最好抛出 SharePoint 异常
throw new SPException("Not Authorized");
