Brainfart? or ASP.NET madness

Posted in ASP.NET.

I need a function from ASP.NET that gives me, reliably and guaranteed, without a config file, the base virtual directory of the current website. So if I'm in c:\inetpub\wwwroot\web (ne http://localhost/web) then I want “/web/.”

But (here's the fart part) I can't seem to find a way that gives it to me INDEPENDANT of the current Context's path. Meaning, if the VERY FIRST (app start) page hit on the site is http://localhost/web/balances/balances.aspx then I still need “/web/“ not “/web/balances/.“

This is the closest I've got:

return HttpRuntime.AppDomainAppVirtualPath + "/";

However, this appears to occasionally (read: flaky) return a different path like /web/images/ or /web/someotherpagedirectory.

What am I missing?

So you need the highest level directory of a web request? Or do you need the base directory of a web application?

For the former, you can do something with the Request.ServerVariables["PATH_INFO"] value, like splitting it on '/' and grabbind the first element.

The latter is easier, and you can use Page.ResolveUrl("~/").

The base dir of the web app can also be gotten from Request.ApplicationPath. Though as Kurt points out, that isn't necessarily the left-most directory in the URL.

How about HttpRequest's ApplicationPath property?

I use

System.AppDomain.CurrentDomain.BaseDirectory

Because you don't have to add a ref to System.Web from other libraries.. I usually do, but using this lets you get away with not having to. No reliance on an HttpRequest object
