c# - Redirect user to Login page with message -


i need display message user if or not registered or signed before accessing page

[authorize] public actionresult learningtopics() {  }

as user directed login page.

how can determine whether user directed login page because of [authorize] attribute can display message 'please login access learner topics.'

you check return url parameter on page in either server code or view code determine if page redirected or not.

for example, if return url parameter returnurl in log in route 

if (!string.isnullorempty(returnurl)) {      // add message "please register" view. }
