c# - GetRequestStream 在数组中停止

Question

我有一个 json 字符串列表，我试图循环并发布到 WebService。它遍历前两个就好了，然后在第 3 次迭代时停止（这发生在第 14 行）。没有错误或任何东西，它似乎停止了。有任何想法吗？

    private static void CacheGetDataUrl(Guid sessionGuid)
    {
        var tokens = Driver.GetDataPostValues();
        foreach (var token in tokens)
        {
            try
            {
                var buffer = Encoding.UTF8.GetBytes(token.Replace("session_identifier", sessionGuid.ToString()));
                var request = (HttpWebRequest)WebRequest.Create(GetDataUrl);
                request.Timeout = 1000000;
                request.Method = "POST";
                request.ContentType = "application/json; charset=utf-8";
                request.ContentLength = buffer.Length;
                using (var postData = request.GetRequestStream())
                {
                    postData.Write(buffer, 0, buffer.Length);
                    postData.Close();
                }
                Console.WriteLine("Response requested for URL {0}", GetDataUrl); 
                Log.Info(String.Format("Response requested for URL {0} using parameters \r\n{1}", GetDataUrl, token));
            }
            catch (Exception)
            {
                Console.WriteLine("Error occurred requesting response for URL {0} using parameters \r\n{1}", GetDataUrl, token);
                Log.Error(String.Format("Error occurred requesting response for URL {0} using parameters \r\n{1}", GetDataUrl, token));
            }
        }

    }

使用一些新属性更改方法，并在收到请求后中止请求似乎已经解决了问题。

    private static void CacheGetDataUrl(Guid sessionGuid)
    {
        var tokens = Driver.GetDataPostValues();
        foreach (var token in tokens)
        {
            try
            {
                var buffer = Encoding.UTF8.GetBytes(token.Replace("session_identifier", sessionGuid.ToString()));
                var request = (HttpWebRequest)WebRequest.Create(GetDataUrl);
                request.KeepAlive = false;
                request.Timeout = System.Threading.Timeout.Infinite;
                request.ProtocolVersion = HttpVersion.Version10;
                request.Method = "POST";
                request.ContentType = "application/json; charset=utf-8";
                request.ContentLength = buffer.Length;
                request.ServicePoint.ConnectionLimit = 250;
                using (var postData = request.GetRequestStream())
                {
                    postData.Write(buffer, 0, buffer.Length);
                    postData.Close();
                }

                request.Abort();

                Console.WriteLine("Response requested for URL {0}", GetDataUrl); 
                Log.Info(String.Format("Response requested for URL {0} using parameters \r\n{1}", GetDataUrl, token));
            }
            catch (Exception)
            {
                Console.WriteLine("Error occurred requesting response for URL {0} using parameters \r\n{1}", GetDataUrl, token);
                Log.Error(String.Format("Error occurred requesting response for URL {0} using parameters \r\n{1}", GetDataUrl, token));
            }
        }
    }
