I'm trying to check an url validation but sometimes it takes too much time:

C#

WebClient webClient = new WebClient();
Stream strm = webClient.OpenRead(url);
string req = strm.CanRead.ToString();

I think you can easy check whether an URL is valid like this:

C#

WebClient webClient = new WebClient();

try 
{
        Stream strm = webClient.OpenRead(URL);    
        // No exception, so the URL is valid!                               
}
catch (WebException we) {
        // houston we've got a problem (URL invalid)
        throw we;
}

It is enough because if the URL is invalid the exception will be thrown.
