Decoding http link in .NET

Question

I am opening a page from my javascript and passing variable to it like below

 <script type="text/javascript">
        function myFunction(what) {
            var valu = what.value;
            var w = window.open("playaudio.aspx?" + what.value);

            return false;
        } 

Now on my playaudio.aspx i am doing this to decode back the %2f and %3f etc into / and ?

string FilePath = HttpUtility.HtmlDecode(Request.QueryString.ToString());

but the problem is that the string FilePath remains unchanged . Any advice on how to change the %2f into / .

Answer 1

See HttpUtility.UrlDecode - I believe that's what you're after.

Answer 2

That's because URLs are not HTML encoded.

You need UrlDecode.
