How can I get the baseurl of site?

Question

I want to write a little helper method which returns the base URL of the site. This is what I came up with:

public static string GetSiteUrl()
{
    string ur         


        

Answer 1

I go with

HttpContext.Current.Request.ServerVariables["HTTP_HOST"]

Answer 2

Try this:

string baseUrl = Request.Url.Scheme + "://" + Request.Url.Authority + 
    Request.ApplicationPath.TrimEnd('/') + "/";

Answer 3

string baseUrl = Request.Url.GetLeftPart(UriPartial.Authority)

That's it ;)

Answer 4

I'm using following code from Application_Start

String baseUrl = Path.GetDirectoryName(HttpContext.Current.Request.Url.OriginalString);

Answer 5

The popular GetLeftPart solution is not supported in the PCL version of Uri, unfortunately. GetComponents is, however, so if you need portability, this should do the trick:

uri.GetComponents(
    UriComponents.SchemeAndServer | UriComponents.UserInfo, UriFormat.Unescaped);

Answer 6

Based on what Warlock wrote, I found that the virtual path root is needed if you aren't hosted at the root of your web. (This works for MVC Web API controllers)

String baseUrl = Request.RequestUri.GetLeftPart(UriPartial.Authority) 
+ Configuration.VirtualPathRoot;
