unable to read querystring in asp.net

This is my url which contains 4 querystrings(desc,url,img,title).

http://localhost:4385/Default?desc=Home%20Page&url=http://localhost:4385/&img=http://localhost:4385/images/ribbon-img.png&title=

I read querystrings like below,

 string title = Request.QueryString["desc"];
 string pageurl = Request.QueryString["url"];
 string alttext = Request.QueryString["title"];
 string imageurl = Request.QueryString["img"];

The output i get is:

title=Home Page&url=http://localhost:4385/&img=http://localhost:4385/images/ribbon-img.png&title="

it takes entire url to first querstring, this is not my expected output.

I expect values to all querystring variables

can anyone please help me

The problem is that you are not creating the QueryString with proper encoding. .NET framework has HttpUtility.ParseQueryString Method to simplify this problem of encoding. Try this code

//are you sure your URL doesn't have an ".aspx" extension?
var url = " http://localhost:4385/Default.aspx?";
var queryString = System.Web.HttpUtility.ParseQueryString(string.Empty);
queryString["desc"] = "Home Page";
queryString["url"] = "http://localhost:4385/";
queryString["image"] = "http://localhost:4385/images/ribbon-img.png";
queryString["title"] = "";
Response.Redirect(url + queryString.ToString());

Now the QueryString will look like this.

var urlWithQueryString = " http://localhost:4385/Default.aspx?desc=Home+Page&url=http%3a%2f%2flocalhost%3a4385%2f&image=http%3a%2f%2flocalhost%3a4385%2fimages%2fribbon-img.png&title="

Now parsing can be done using the method you tried

string title = Request.QueryString["desc"];
string pageurl = Request.QueryString["url"];
string alttext = Request.QueryString["title"];
string imageurl = Request.QueryString["image"]; //you have wrongly typed "img" here

The URL format is incorrect i feel, because the slash / character will be sent as %2F in the query string but that was not done in your URL format.

Update: 

Respose.Redirect("http://localhost:4385/Default?desc=Home%20Page&url="+Uri.EscapeDataString("http://localhost:4385/")+"&img="+Uri.EscapeDataString("http://localhost:4385/images/ribbon-img.png")+"&title=");
