??? 最近遇到一個問題請教下，在一個時間控件中寫了一個HttpWebRequest以post的形式發送，設置了發送超時5秒，但當我網絡不好斷了一段時間網絡，然后再連接上后，就不可以繼續發送請求了，不知道有沒有什么可以修復的方法和屬性，下面是我的代碼段 strParams = HttpUtility.UrlPathEncode(strParams); ????? ??????????????? byte[] byteRequest = Encoding.Default.GetBytes(strParams);//編碼???? ??????????????? HttpWebRequest httpWebRequest = (HttpWebRequest)WebRequest.Create(new Uri(consumer.ConsumerAddress.ToString().Trim()));? ??????????????? httpWebRequest.Credentials = CredentialCache.DefaultCredentials; ??????????????? httpWebRequest.ContentType = "application/x-www-form-urlencoded";//這一個參數似乎是必需的。 ??????????????? httpWebRequest.Method = "POST";//這個是請求方法，必須是POST，這個可以通過分析實際登錄的情況得到采用的方法 ????? ???? ?????????? httpWebRequest.Timeout = consumer.ConsumerTimeOut; ??????????????? httpWebRequest.ContentLength = byteRequest.Length;//POST數據的長度，這個參數是必需的。 ????????????? ???????????? ?? httpWebRequest.ProtocolVersion = HttpVersion.Version10; ??????????????? httpWebRequest.KeepAlive = false; ??????????????? //下面是發送數據到服務器??????????? ??????????????? Stream stream = httpWebRequest.GetRequestStream();????????????? ??????????????? stream.Write(byteRequest, 0, byteRequest.Length); ??????????????? stream.Close(); ??????????????? ?????????????? ?HttpWebResponse webResponse = (HttpWebResponse)httpWebRequest.GetResponse();//取服務器的響應 ??????????? ?????????? ???? StreamReader streamReader = new StreamReader(webResponse.GetResponseStream(), Encoding.UTF8); 在最后一句會有異常
