Question

我使用webbrowser控件打开一个网站，然后将cookie保存在cookieContainer中，稍后使用HTTPwebrequest处理前向浏览页面等。

出现问题，当我进行搜索并返回100页时，在第一页上，它会保存一个名为ABC的cookie，我将其添加到cookiecontainer并移至下一页，再次在第二页上Cookie命名：ABC有一些价值，但现在我在cookiecontainer中有两个相同的cookie，当我移动到下一页时它不起作用，因为它采用了第一个混乱的东西。

如何解决这个问题？

HttpWEBREQUEST FUNCTION：

 public string getHtmlCookies(string url)
    {
        string responseData = "";
        try
        {
            HttpWebRequest request = (HttpWebRequest)WebRequest.Create(url);
            request.Accept = "*/*";
            request.AllowAutoRedirect = true;
            request.UserAgent = "Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.2; .NET CLR 1.0.3705;)";
            request.Timeout = 30000;
            request.Method = "GET";
            request.CookieContainer = yummycookies;

            HttpWebResponse response = (HttpWebResponse)request.GetResponse();
            if (response.StatusCode == HttpStatusCode.OK)
            {
                foreach (Cookie cookie in response.Cookies)
                {
                    string name = string.Empty;
                    name = cookie.Name;
                    string value = cookie.Value;
                    string path = "/";
                    string domain = "www.example.com";
                    yummycookies.Add(new Cookie(name.Trim(), value.Trim(), path, domain));

                }


                Stream responseStream = response.GetResponseStream();
                StreamReader myStreamReader = new StreamReader(responseStream);
                responseData = myStreamReader.ReadToEnd();
            }
            response.Close();


        }
        catch (Exception e)
        {
            responseData = "An error occurred: " + e.Message;
        }

        return responseData;

    }

您可以使用SetCookies方法。

var container = new System.Net.CookieContainer();
var uri = new Uri("http://www.example.com");
container.SetCookies(uri,"name=value");
container.SetCookies(uri,"name=value1");

致电GetCookies(uri)会给出一个包含Value=value1的Cookie。

在您的情况下，代码将类似于

var uri = new Uri("http://www.example.com");
yummycookies.SetCookies(uri, response.Headers[HttpResponseHeader.SetCookie]);

如何在cookie容器c＃中删除/更新cookie？
