How do you prevent the WebClient class from automatically following the location in headers?

问题

Is it possible on the WebClient class?

E.g. something like:

MyWebClient.AllowAutoRedirect = false; (of HttpWebRequest) 

回答1:

You could write a custom web client and enable this functionality:

public class WebClientEx : WebClient
{
    protected override WebRequest GetWebRequest(Uri address)
    {
        var request = (HttpWebRequest)base.GetWebRequest(address);
        request.AllowAutoRedirect = false;
        return request;
    }
}

and then:

using (var client = new WebClientEx())
{
    Console.WriteLine(client.DownloadString("http://google.com"));
}
