ASP网站根网址

Question

Sorry for question that is already asked few times and on other forums, but I really didn't find a solution that gives what I need.

I have an ASP.NET MVC site. And in one of the controllers I need to find the root url of the site (For example http://myhost:7777/MyVirtualDir/ ). I need it as is, not any relative urls - only full absolute ROOT url of the site. The reason is that I will use this url from other application to access service, hosted on site. I tried many dirrerent variants and proposed solutions from other forums, including:

VirtualPathUtility.ToAbsolute("~") // Returns "/" - it returns relative url
Url.Content("~")  //Returns "/MyVirtualDir/" - only virtual directory path part

and all other ToAbsolute return relative paths.

I invented the following :

Request.Url.ToString().Substring(0, Request.Url.ToString().Length - Request.Url.PathAndQuery.Length + Url.Content("~").Length);

Looks like it works . But there is too much magic here. Is there a normal way to retrieve such path ?

Answer 1

As far as I can tell, there is no built-in functionality to grab specifically the root of the application with virtual paths in a single call. The simplest solution I can find is this:

Request.Url.GetLeftPart(UriPartial.Authority) + Request.ApplicationPath
