如何在Sharepoint中引发401（未经授权的访问）异常？

Question

正如标题所说，我需要（从自定义SharePoint页面后面的C＃代码）引发一个401错误页面。有什么帮助吗？

Answer 1

试试这个：

throw new HttpException(401, "Unauthorized access");

Answer 2

如果异常与SharePoint相关，则最好抛出SharePoint异常

throw new SPException("Not Authorized");

另见http://msdn.microsoft.com/en-us/library/microsoft.sharepoint.spexception.aspx

Answer 3

return new HttpUnauthorizedResult();

Answer 4

试试这个：

throw new UnauthorizedAccessException($"Some message");
