Can't get site root url in asp mvc

Question

I need to get site root url in razor page in javascript code:

... var siteRootUrl = '@Url.Content("~")'; ... 

But all I get from this is '/'.

Answer 1

To get the current host with port (mysite.com, www.mysite.com or localhost:9876)

 Request.Url.Authority 

To get your current application folder: (/ or /appfolder/)

 Url.Content("~/") 

To mix them?

 String.Format("{0}://{1}{2}",Request.Url.Scheme, Request.Url.Authority,Url.Content("~/")) 

OR (As torm pointed out)

 Url.Action("", null, null, Request.Url.Scheme)  Url.Action("", null, null, "http")  Url.Action("", null, null, "https")  

To generate an Action URL:

 Url.Action("About","Home",null,"http")
