Extending HttpWebRequest

Question

class AdvancedWebRequest : HttpWebRequest {
    private static readonly ILog log = log4net.LogManager.GetLogger(typeof(AdvancedWebRequest));

    public AdvancedWebRequest(string url, CookieContainer cookies = null) {
        Create(url);
        UserAgent = "Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.22 (KHTML, like Gecko) Chrome/25.0.1364.97 Safari/537.22";
        Referer = Address.AbsoluteUri;

        if (cookies == null) {
            CookieContainer = Program.request.CookieContainer;
        } else {
            CookieContainer = cookies;
        }
    }
}

This is something I want to do, so basically get the HttpWebRequest with some variables already set, so I must not set them always myself.

Getting error:

'System.Net.HttpWebRequest.HttpWebRequest()' is obsolete: 'This API supports the .NET Framework infrastructure and is not intended to be used directly from your code.' \Extensions\AdvancedWebRequest.cs   14  10  

Any suggestions, can't HttpWebRequest be really extended?

Answer 1

You can not inherit fromHttpWebRequest but you can inherit from WebRequest

Check the answers from the similar question here.

Answer 2

You could use Extension Methods like this:

public static DoRequest(this HttpWebRequest req){
//do something
}

and then you can call this method like this:

webrequest.DoRequest();
