Get application path without using httpcontext. (asp.net)

Question

How to do it?

I don\'t want to use this:

HttpContext.Current.Server.MapPath

Is there a similar function that I can call without req

Answer 1

I have run across this question when looking for way to compute an URL (permalinks in the Web application) to provide in some e-mail notifications.

These were generated on another thread, so HttpContext was not available and I wanted to avoid putting URL related information in the queue table used to generate the e-mails.

The code:

public static String GetCurrentAppDomainBasePath(String prefix = "http://")
{
   return String.Format("{0}{1}{2}", 
      prefix,
      System.Net.Dns.GetHostEntry("").HostName, 
      System.Web.HttpRuntime.AppDomainAppVirtualPath
   );
}

The function returns the full virtual path like: http://full-host-name/AppName. Of course, there are some limitations: hardcoded protocol (http, https etc.) and using hostname instead of domain name (fails if multiple domains are defined on a single machine).
