我正在编写一个.NET应用程序,它应该将数据发布到另一个.NET应用程序.我使用以下代码来请求登录页面

WebProxy proxy = new WebProxy("http://proxy:80/", true);
HttpWebRequest webRequest = WebRequest.Create(LOGIN_URL) as HttpWebRequest;
//proxy.Credentials = new NetworkCredential("myusername", "mypassword", "domain"); 
// webRequest.Proxy = proxy;
webRequest.Proxy = WebRequest.DefaultWebProxy;

StreamReader responseReader = new StreamReader
                                  (webRequest.GetResponse().GetResponseStream());
string responseData = responseReader.ReadToEnd();

但它在这条线上失败了

StreamReader responseReader = new StreamReader
                                  (webRequest.GetResponse().GetResponseStream());

带有错误消息:

System.Net.WebException: The underlying connection was closed: The connection was 
                         closed unexpectedly.
