HttpWebRequest采集时添加:httpWebRequest.CookieContainer = new CookieContainer();就能远程挂载上cookie,那么怎样去读取挂载上的cookie呢?

下面方法为大家解除烦恼。

遍历方法:

public static List<Cookie> GetAllCookies(CookieContainer cc) { List<Cookie> lstCookies = new List<Cookie>(); Hashtable table = (Hashtable)cc.GetType().InvokeMember("m_domainTable", System.Reflection.BindingFlags.NonPublic | System.Reflection.BindingFlags.GetField | System.Reflection.BindingFlags.Instance, null, cc, new object[] { }); StringBuilder sb = new StringBuilder(); foreach (object pathList in table.Values) { SortedList lstCookieCol = (SortedList)pathList.GetType().InvokeMember("m_list", System.Reflection.BindingFlags.NonPublic | System.Reflection.BindingFlags.GetField | System.Reflection.BindingFlags.Instance, null, pathList, new object[] { }); foreach (CookieCollection colCookies in lstCookieCol.Values) foreach (Cookie c in colCookies) { lstCookies.Add(c); sb.AppendLine(c.Domain + ":" + c.Name + "____" + c.Value + "\r\n"); } } return lstCookies; }

使用:

List<Cookie> _cookieList = GetAllCookies(req.CookieContainer); string _cookieValue = _cookieList[0].ToString();
