c# - 禁用 HttpWebRequest 的图像下载

Question

是否可以说一个网络请求只从站点获取基于文本的数据？如果是，我应该怎么做？

我唯一能想到的就是在响应字符串中搜索并删除所有图像标签。但这是一种非常糟糕的方式...

编辑:这是我的代码片段:

            string baseUrl = kvPair.Value[0];
            string loginUrl = kvPair.Value[1];
            string notifyUrl = kvPair.Value[2];
            cc = new CookieContainer();
            string loginDetails = DataCollector.GetLoginDetails(baseUrl, ref cc);
            HttpWebRequest request = (HttpWebRequest)WebRequest.Create(loginUrl);
            request.Method = "POST";
            request.Accept = "text/*";
            request.ContentType = "application/x-www-form-urlencoded; charset=UTF-8";
            request.CookieContainer = cc;
            request.UserAgent = "Mozilla/5.0 (Windows NT 6.1; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/53.0.2785.116 Safari/537.36";
            Byte[] data = Encoding.ASCII.GetBytes(loginDetails);
            request.ContentLength = data.Length;
            using (Stream s = request.GetRequestStream())
            {
                s.Write(data, 0, data.Length);
            }
            HttpWebResponse res = (HttpWebResponse)request.GetResponse();
            request = (HttpWebRequest)WebRequest.Create(notifyUrl);
            request.UserAgent = "Mozilla/5.0 (Windows NT 6.1; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/53.0.2785.116 Safari/537.36";
            request.CookieContainer = cc;
            res = (HttpWebResponse)request.GetResponse();
            Stream streamResponse = res.GetResponseStream();
            using (StreamReader sr = new StreamReader(streamResponse))
            {
                ViewData["data"] += "<div style=\"float: left; margin-bottom: 50px;\">" + sr.ReadToEnd() + "</div>";
            }

我为自己找到了一个很好的编码解决方案:

public static string StripImages(string input)
{
   return Regex.Replace(input, "<img.*?>", String.Empty);
}

这会杀死所有图像，但只会在您加载完所有图像后立即执行，因此在此解决方案中不会节省传输的数据...
