回答1:

Request.UrlReferrer

But this isn't guaranteed to be correct or even exist.

回答2:

Request.UrlReferrer can be used to retrieve the previous page url from where the current page has been redirected.

回答3:

The referer URL should be in the HTTP headers on the request.

E.g. Uri MyUrl = Request.UrlReferrer
