  there is nothing like "#" in http://localhost:0003/index.aspx#access_token=qwqwqwqwqw

  that got to be "?" so it becomes http://localhost:0003/index.aspx?access_token=qwqwqwqwqw

  that is what you call querystring and you can access it on index page like this:

  string qstring = Request.QueryString["access_token"]; //C#

  Dim qstring as string = Request.QueryString("access_token") //VB

  The # sign is not passed over to the server side. So you can not directly get it in code behind. There is a work around using jQuery/JavaScript where you receive it in client side and set it on a server side control and send to server.

  See the following link for the example:

  Hi,

  Generally the QueryString format will be like this!

  http://www.google.com/q=helloword

  which the above QueryString can be retrieved through Request.QueryString["q"]!

  If you wan to retrieve values from your URL, then write custom logic to do that!

  Check the sample code below!

  string strURL = Request.Url.ToString();
              string[] strQueryString =  strURL.Split(new char[]{'#'});
  
              foreach (string item in strQueryString)
              {
                  string[] strQueryValues = item.Split(new char[]{'='});
                  string strKey = strQueryValues[0];
                  string strValue = strQueryValues[1];
              }

  Hope it helps u...

  using System.IO;

  using system.Net;

  WebClient client = new WebClient();
  string htmlCode = client.DownloadString(http://localhost:0003/index.aspx#access_token=qwqwqwqwqw);

  uisng the above code you will get data from that site in string format and then you can manipulate by   removing  html tables 

  by using c# functions like replace() or remove  or any other metgod to get data 

  I have tried this in my page and is working fine
