     CookieContainer myCookieContainer = new CookieContainer();
        //string[] cookstr = cookieStr.Split(';');
        //CookieCollection cookieCollection = new CookieCollection();

        //foreach (string str in cookstr)
        //{
        //    string name = str.Substring(0, str.IndexOf("="));
        //    string value = str.Substring(str.IndexOf("=") + 1);
        //    Cookie ck = new Cookie(name, value);
        //    cookieCollection.Add(ck);

        //}
        //myCookieContainer.Add(new Uri("www.58.com"), cookieCollection);
        myCookieContainer.SetCookies(new Uri("www.58.com"), cookieStr);
        string content = string.Empty;
        imgUrlList.ForEach(delegate(string url)
        {
            HttpWebRequest request = (HttpWebRequest)HttpWebRequest.Create(url);
            request.Method = "GET";
            request.UserAgent = "Mozilla/5.0 (Windows NT 6.1) AppleWebKit/537.1 (KHTML, like Gecko) Chrome/21.0.1180.89 Safari/537.1";
            request.KeepAlive = true;
            request.Accept = "*/*";
            request.Referer = "http://post.58.com/541/8/s5?pts=1403055598929";
            request.Headers.Add("Accept-Encoding", "gzip,deflate,sdch");
            request.Headers.Add("Accept-Language", "zh-CN,zh;q=0.8");
            request.Headers.Add("Accept-Charset", "GBK,utf-8;q=0.7,*;q=0.3");
            request.CookieContainer = myCookieContainer;
            Stream Stream;
            Stream = request.GetRequestStream();
            //Stream.Write(streamByImg, 0, streamByImg.Length);

如上边所示代码,我尝试了很多方式来将HttpRequest请求的CookieContainer属性赋值,发下怎么弄都无法实现,在我注释的那段里,

 Cookie ck = new Cookie(name, value);
我用直接new Cookie的方式,提交,发现第一次new的时候可以,第二次的时候就直接没有异常,直接退出该方法的执行了,没有执行 cookieCollection.Add(ck);方法,请问,这是为什么?下班是登陆后的cookie

request.Headers.Add("Cookie", cookieStr);

我用了你这种方法,发下到了Stream = request.GetRequestStream();这一步,直接跳出了,也不报错,没有往下边执行了,这是提交的请求内容有问题吗?

@就叫我好人吧: 你能给我演示下什么叫着“直接跳出了,也不报错”吗?

@Launcher: 

  public string downImgFor58(List<string> urlImg)
    {
        //CookieContainer myCookieContainer = new CookieContainer();
        //string[] cookstr = cookieStr.Split(';');
        //CookieCollection cookieCollection = new CookieCollection();

        //foreach (string str in cookstr)
        //{
        //    string name = str.Substring(0, str.IndexOf("="));
        //    string value = str.Substring(str.IndexOf("=") + 1);
        //    Cookie ck = new Cookie(name, value);
        //    cookieCollection.Add(ck);

        //}
        //myCookieContainer.Add(new Uri("www.58.com"), cookieCollection);


        //myCookieContainer.SetCookies(new Uri("www.58.com"), cookieStr);

        string content = string.Empty;
        imgUrlList.ForEach(delegate(string url)
        {
            HttpWebRequest request = (HttpWebRequest)HttpWebRequest.Create(url);
            request.Method = "GET";//这里改为post 后面是你想要post的数据,更多参数的设置在header建议看看msdn
            request.UserAgent = "Mozilla/5.0 (Windows NT 6.1) AppleWebKit/537.1 (KHTML, like Gecko) Chrome/21.0.1180.89 Safari/537.1";
            request.KeepAlive = true;
            request.Accept = "*/*";
            request.Referer = "http://post.58.com/541/8/s5";
            request.Headers.Add("Accept-Encoding", "gzip,deflate,sdch");
            request.Headers.Add("Accept-Language", "zh-CN,zh;q=0.8");
            request.Headers.Add("Accept-Charset", "GBK,utf-8;q=0.7,*;q=0.3");
            //request.CookieContainer = myCookieContainer;
            //request.Headers.Add("Cookie", cookieStr);
            Stream Stream;
            Stream = request.GetRequestStream();
            //Stream.Write(streamByImg, 0, streamByImg.Length);
            Stream.Close();

            HttpWebResponse responseSorce = (HttpWebResponse)request.GetResponse();
            StreamReader reader = new StreamReader(responseSorce.GetResponseStream(), Encoding.UTF8);
            reader.ReadToEnd();
        });


        return @"http://pic.58.com/p1/tiny/" + content;
    }

这本来是一个方法嘛,在方法执行到Stream = request.GetRequestStream();这一步,他就没有执行Stream.Close();以下的代码了。

@就叫我好人吧: 你确定没有抛出异常吗?你不需要 try catch 一下?
