标题: 基础连接已经关闭: 发送时发生错误
做微信授权的时候需要post网址，然后传到服务器上，一切正常，但是过了几个小时就报错了。。System.Net.WebException: 基础连接已经关闭: 发送时发生错误。 ---> System.IO.IOException: 从传输流收到意外的 EOF 或 0 个字节。

代码如下：
System.GC.Collect();
         if (string.IsNullOrEmpty(url))
         {
            throw new ArgumentNullException("url");
         }

         HttpWebRequest request = null;
         Stream stream = null;//用于传参数的流

         try
         {
            //如果是发送HTTPS请求
            if (url.StartsWith("https", StringComparison.OrdinalIgnoreCase))
            {
                  ServicePointManager.ServerCertificateValidationCallback = new RemoteCertificateValidationCallback(CheckValidationResult);
                  request = WebRequest.Create(url) as HttpWebRequest;
                  //创建证书文件
                  System.Security.Cryptography.X509Certificates.X509Certificate objx509 = new System.Security.Cryptography.X509Certificates.X509Certificate(@"\\Oauth\zjs.cer");
                  //添加到请求里
                  request.ClientCertificates.Add(objx509);
                  request.ProtocolVersion = HttpVersion.Version10;
            }
            else
            {
                  request = WebRequest.Create(url) as HttpWebRequest;
            }

            request.Method = "POST";//传输方式
            request.ContentType = "application/x-www-form-urlencoded";//协议
            request.UserAgent = DefaultUserAgent;//请求的客户端浏览器信息,默认IE
            request.Timeout = 10000;//超时时间，写死6秒
            request.KeepAlive = false;
            System.Net.ServicePointManager.DefaultConnectionLimit = 1000;
            //随同HTTP请求发送的Cookie信息，如果不需要身份验证可以为空
            if (cookies != null)
            {
                  request.CookieContainer = new CookieContainer();
                  request.CookieContainer.Add(cookies);
            }

            //如果需求POST传数据，转换成utf-8编码
            byte[] data = requestEncoding.GetBytes(parameters);
            request.ContentLength = data.Length;

            stream = request.GetRequestStream();
            stream.Write(data, 0, data.Length);

            stream.Close();
            request.Abort();

         }
         catch (Exception ee)
         {
            //写日志
            //LogHelper.
         }
         finally
         {
            if (stream != null)
            {
                  stream.Close();
                  stream.Dispose();
            }
         }

         return request.GetResponse() as HttpWebResponse;

《--------------------------------------------------------》出错之后程序重新传一下就又好了，过几个小时又出问题了。就这么如此反复，我是没办法了。。求大神给看看。。
