How to get URL path in C#

Main URL : http://localhost:8080/mysite/page.aspx?p1=1&p2=2

Get different parts of URL in C#.

Value of HttpContext.Current.Request.Url.Host
localhost

Value of HttpContext.Current.Request.Url.Authority
localhost:8080

Value of HttpContext.Current.Request.Url.AbsolutePath
/mysite/page.aspx

Value of HttpContext.Current.Request.ApplicationPath
/mysite

Value of HttpContext.Current.Request.Url.AbsoluteUri
http://localhost:8080/mysite/page.aspx?p1=1&p2=2

Value of HttpContext.Current.Request.RawUrl
/mysite/page.aspx?p1=1&p2=2

Value of HttpContext.Current.Request.Url.PathAndQuery
/mysite/page.aspx?p1=1&p2=2

Don't treat it as a URI problem, treat it a string problem. Then it's nice and easy.

String originalPath = new Uri(HttpContext.Current.Request.Url.AbsoluteUri).OriginalString;
String parentDirectory = originalPath.Substring(0, originalPath.LastIndexOf("/"));

Really is that easy!

Edited to add missing parenthesis.

Replace this :

            string sRet = oInfo.Name;
            Response.Write(sPath.Replace(sRet, ""));

With following:

        string sRet = oInfo.Name;           
        int lastindex = sRet.LastIndexOf("/");
        sRet=sRet.Substring(0,lastindex)
        Response.Write(sPath.Replace(sRet, ""));
