How to get query string with multiple param

I have a url:

http://www.abc.com?refurl=/english/info/test.aspx?form=1&h=test&s=AB

If I use

Request.QueryString["refurl"

but gives me

/english/info/test.aspx?form=1

instead I need full url

/english/info/test.aspx?form=1&h=test&s=AB

Fix the problem, and the problem is that you place a full url as parameter refurl with out encoding it.

So where you create that url string use the UrlEncode() function, eg:

"http://www.abc.com?refurl=" + Server.UrlEncode(ReturnUrlParam)

where
ReturnUrlParam="/english/info/test.aspx?form=1&h=test&s=AB";

I had similar situation some time ago. I solved it by encoding refurl value. now my url looks similar to that one: http://www.abc.com?refurl=adsf45a4sdf8sf18as4f6as4fd

I have created 2 methods:

public string encode(string);
public string decode(string);

Before redirect or where you have your link, you simple encode the link and where you are reading it, decode before use:

Response.redirect(String.Format("http://www.abc.com?refurl={0}", encode(/english/info/test.aspx?form=1&h=test&s=AB));

And in the page that you are using refurl:

 $refUrl = Request.QueryString["refurl"];
 $refUrl = decode($refUrl);

EDIT: encode/decode methods I actually have as extension methods, then for every string I can simply use string.encode() or string.decode().

For that particular case you shouldn't use QueryString, (since your query string contains three parameters,) instead use Uri class, and Uri.Query will give you the required result. 

Uri uri  = new Uri(@"http://www.abc.com?refurl=/english/info/test.aspx?form=1&h=test&s=AB");
string query = uri.Query;

Which will give you :

?refurl=/english/info/test.aspx?form=1&h=test&s=AB

Later you can remove ?refurl= to get the desired output.

I am pretty sure there is no direct way in the framework for your particular requirement, you have to implement that in your code and that too with string operations.
