How to get ASP .net web application's virtual path?

Question

I have a page http://localhost:65248/ZeroLabs/msg_preview.aspx.

I want to get http://localhost:65248/ZeroLabs part.

My code runs in this page Page_Load event.

I didn't find anything good in Request.Url.

Currently I use this:

//http + :// + localhost:65248 + /ZeroLabs
string omg_wtf = Request.Url.Scheme + "://" + Request.Url.Authority + System.Web.Hosting.HostingEnvironment.ApplicationVirtualPath;

I feel this isn't a way how I supposed to get what I want. Any less ugly way, please?

Well, is Request.Url.AbsoluteUri.Substring(0, Request.Url.AbsoluteUri.LastIndexOf("/")) any less "ugly"? Please define "ugly" in an objective, non-opinionated way. — Heretic Monkey

@HereticMonkey - Well... I hoped for some single property... but your way is less ugly too... Or maybe no if we have something like that ?asd=qwe/sdf... Or maybe yes if we can't have something like that in AbsoluteUri... — Kosmo零

Curious why you want it. Generally you can just use tilde to construct paths to resources. There's a bunch of ways to get the full path though here — Nikki9696

@Nikki9696 - I use it to concatenate with other page names in code. For example I build an list of *.aspx pages stored in physical path (string[] paths = Directory.GetFiles(path, "*.aspx")) corresponding to http://localhost:65248/ZeroLabs and give it to user, so he can visit them. It's like http://localhost:65248/ZeroLabs + / + paths[i]. — Kosmo零

I am not 100% sure, as it's a long time using web pages with Asp.Net web forms. But If I recall correctly, you just need to use ~ for getting the virtual path of you web application/website.

So ~/ZeroLabs should work for you. Just give it a try.

Also see this link on Stackoverflow. It might be useful.

Thanks

Thanks. I found HttpContext.Current.Request.Url.GetLeftPart(UriPartial.Authority) + HttpRuntime.AppDomainAppVirtualPath; there. Still not a single property, yet this this better than my junk code.
