url decode

Hi,

How can I decode url using vb.net or c# or asp.net, the example is as below:


encoded:
http://en.wikipedia.org/wiki/simple:car

Decoded by browser:
http://simple.wikipedia.org/wiki/Car
Other scenario are characters like %6C in url.

I need clean url so I can use with DownloadString of webClient to scrape data.

Thank you

Well basic decoding is done via the HttpServerUtility.UrlDecode method

But that doesn't handle the URL conversion that wikipedia is doing....

Your example is not encoded therefore cannot be decoded.  It is being converted by wikipedia.

WebClient wc = new WebClient();
            wc.Headers.Add("User-Agent: Mozilla/4.0 (compatible; MSIE 8.0)");
            string s = wc.DownloadString("http://en.wikipedia.org/wiki/simple:car");
