c# - 扩展 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;
        }
    }
}

这是我想做的事情，所以基本上获取 HttpWebRequest 时已经设置了一些变量，所以我不能总是自己设置它们。

获取错误:

'System.Net.HttpWebRequest.HttpWebRequest()' is obsolete: 'This API supports the .NET Framework infrastructure and is not intended to be used directly from your code.'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

有什么建议吗，HttpWebRequest真的不能扩展吗？

Answer 1

你不能继承自HttpWebRequest 但你可以继承自WebRequest
