c#通過檔案儲存體 調用cookies的代碼

最近研究paperpass 論文檢測系統 登入的時候 考慮到需要把登入資訊

 儲存下來，但是c#不想php，有這個功能，不能把cookies儲存文本，並發送到伺服器，所以就寫了一段代碼

顯示 get 的方式擷取網頁的原始碼 1 /// <summary>

 2         /// 擷取頁面的html代碼
 3         /// </summary>
 4         /// <param name="URL">地址</param>
 5         /// <param name="Referer">來路</param>
 6         /// <param name="Cookies">cookies</param>
 7         /// <returns></returns>
 8         protected string getHtml(string URL, string Referer, string CookiesFile ,bool AutoRe)//擷取指定地址的源檔案
 9         {
10             HttpWebRequest getRequest = (HttpWebRequest)WebRequest.Create(URL);
11             CookieContainer Cookies = null;
12             if (!String.IsNullOrEmpty(CookiesFile)&&File.Exists(CookiesFile))
13             {
14                 Cookies = getCookieContainer(CookiesFile);
15                
16                 getRequest.CookieContainer = Cookies;
17             }
18             getRequest.Accept = "*/*";
19             getRequest.UserAgent = "Mozilla/4.0 (compatible; MSIE 8.0; Windows NT 5.1;)";
20             getRequest.KeepAlive = false;
21             getRequest.AllowAutoRedirect = AutoRe;
22             if (!String.IsNullOrEmpty(Referer))
23             {
24                 getRequest.Referer = Referer;
25             }
26             try
27             {
28                 HttpWebResponse getResponse = (HttpWebResponse)getRequest.GetResponse();
29                 string[] LocationUlr = getResponse.Headers.GetValues("Location");
30 
31                 if (Cookies != null && getResponse.Cookies.Count>0)
32                 {
33                     Cookies.Add(getResponse.Cookies);
34                     //儲存Cookies檔案
35                     saveCookieContainer(Cookies, CookiesFile);
36                 }
37                 //如果是轉向的
38                 if (!AutoRe && LocationUlr != null && LocationUlr.Length > 0)
39                 {
40                     getResponse.Close();
41                     return LocationUlr[0];
42                 }
43                 StreamReader readStream = new StreamReader(getResponse.GetResponseStream(), Encoding.UTF8);
44                 var TheHtml = readStream.ReadToEnd();
45                 readStream.Close(); readStream.Dispose();              
46                 getResponse.Close();
47                 
48                 return TheHtml;
49             }
50             catch (Exception E)
51             {
52                 writeLog(E.ToString(), ownsHttpContext.Server.MapPath("/"));
53                 return null;
54             }
55             finally
56             {
57                 getRequest.Abort();
58             }
59         }

其中的getCookieContainer函數 從檔案讀取
CookieContainer  ，saveCookieContainer函數把CookieContainer儲存到檔案！

兩個函數如下  /// <summary>

        /// 遍曆CookieContainer
        /// </summary>
        /// <param name="cc"></param>
        /// <returns></returns>
        public static List<Cookie> GetAllCookies(CookieContainer cc)

                System.Reflection.BindingFlags.NonPublic | System.Reflection.BindingFlags.GetField |
                System.Reflection.BindingFlags.Instance, null, cc, new object[] { });

            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)
