c#通过文件存储 调用cookies的代码
最近研究paperpass 论文检测系统 登录的时候 考虑到需要把登录信息
保存下来，但是c#不想php，有这个功能，不能把cookies保存文本，并发送到服务器，所以就写了一段代码
显示 get 的方式获取网页的源代码 1 /// <summary>
2 /// 获取页面的html代码
3 /// </summary>
4 /// <param name="URL">地址</param>
5 /// <param name="Referer">来路</param>
6 /// <param name="Cookies">cookies</param>
7 /// <returns></returns>
8 protected string getHtml(string URL, string Referer, string CookiesFile ,bool AutoRe)//获取指定地址的源文件
9 {
10 HttpWebRequest getRequest = (HttpWebRequest)WebRequest.Create(URL);
11 CookieContainer Cookies = null;
12 if (!String.IsNullOrEmpty(CookiesFile)&&File.Exists(CookiesFile))

其中的getCookieContainer函数 从文件读取 CookieContainer ，saveCookieContainer函数把CookieContainer保存到文件！
两个函数如下 /// <summary>
/// 遍历CookieContainer
/// </summary>
/// <param name="cc"></param>
/// <returns></returns>
public static List<Cookie> GetAllCookies(CookieContainer cc)
{

| System.Reflection.BindingFlags.Instance, null, pathList, new object[] { });
foreach (CookieCollection colCookies in lstCookieCol.Values)
foreach (Cookie c in colCookies) lstCookies.Add(c);
}
return lstCookies;
}
