Q:

How to encode url in javascript and decode it in C#

I have a url with querystrings through which some data are passed. I want to retrieve the data in the server side. What is the solution for this problem

A:

You can use javascript's  escape function to encode the URL.
Example : 
escape("It's me!") // result: It%27s%20me%21

URL Decoding in C# using Uri.UnescapeDataString() function.
Example : 
s = "%46%69%67%68%74%20%74%68%65%20%70%6F%77";
Uri.UnescapeDataString(s); 

EDIT -------------------------
To Parse Query parameters in C# use
NameValueCollection qscoll = HttpUtility.ParseQueryString(querystring);

Hope this will help.
Thanks!

A:

You can use escape ( http://www.w3schools.com/jsref/jsref_escape.asp ) or encodeURI ( http://www.w3schools.com/jsref/jsref_encodeuri.asp ) to encode on Javascript side.
On server side:
For C# - Use System.Web.HttpUtility.UrlDecode to decode ( http://msdn.microsoft.com/en-us/library/adwtk1fy.aspx )
For Java - Use URLDecoder to decode ( http://download.oracle.com/javase/1.5.0/docs/api/java/net/URLDecoder.html )
For PHP - Use urldecode ( http://php.net/manual/en/function.urldecode.php )
