问题 I need to make CORS from/to various Sharepoint domains, and of course handle the OPTIONS preflight request. After a lot of research I found that this solution is (almost) the best for my needs.

阅读更多关于 Get names of Online users connected to a Server

问题 I am new to asp.net. I have gone through this link which has shown how to count the online users connected to a server using asp.net. ( which is working when I tried ) My question is: What should I change in that code (Global.asax) so that It shows all the names of the connected users instead of counting them.
