c#的HttpWebResponse 怎么老是报The underlying connection was closed
我是用循环来调用的.不是马上出现,出现的时间不定...奇怪了
string loginUrl = "http://192.168.1.101/DoServer.Class.php";
Encoding encoding = Encoding.GetEncoding("UTF-8");
HttpWebResponse response = HttpWebResponseUtility.CreatePostHttpResponse(loginUrl, parameters, null, null, encoding, null);
//response.ti
StreamReader sr = new StreamReader(response.GetResponseStream(), Encoding.UTF8);
String retValue = sr.ReadToEnd();
sr.Close();
return retValue;
System.Net.WebException: The underlying connection was closed: A connection that was expected to be kept alive was closed by the server.

[解决办法]是不是多线程调用了同一个对象的同一个方法.
你在多线程里new这个对象,调用他的方法吧.避免多线程调用太频繁,服务器有链接时长限制
