            Parallel.ForEach(result, (item) =>
            {
                try
                {
                    ReadUrlContent("http://dataapi.eastmoney.com:8080/bbsj/stock.aspx?code=" + item.StockCode + "", item.StockCode);

            Console.WriteLine("end:" + DateTime.Now.ToString());
            Console.WriteLine(DateTime.Now.ToString());
 public static void ReadUrlContent(string rUrl, string code)
        {
            byte[] buf = new byte[8192];
            HttpWebRequest request = (HttpWebRequest)WebRequest.Create(rUrl);
            HttpWebResponse response = (HttpWebResponse)request.GetResponse();
            Stream resStream = response.GetResponseStream();
            string tempString = null;
            int count = 0;
            using (FileStream fs = new FileStream("D:\\eastmoney\\data\\bbsj\\page\\" + code + ".html", FileMode.OpenOrCreate, FileAccess.Write))

                do
                {
                    count = resStream.Read(buf, 0, buf.Length);
                    if (resStream.Read(buf, 0, buf.Length) != 0)
                    {

                        fs.Write(buf, 0, count);
                    }
                }
                while (count > 0);
                resStream.Close();
                fs.Close();
            }

[解决办法]
500错误是服务器引发的，你没有办法。

可能的原因：
你提交的数据不合法
服务器有bug，导致内部错误
服务器防止数据被滥用，对你频繁的请求做了限制
