代码：

 HttpWebRequest myReq = (HttpWebRequest)WebRequest.Create(PostingUrl); 
    CredentialCache CredMCCache = new CredentialCache(); 
     myReq.PreAuthenticate = true; 
     CredMCCache.Add(new System.Uri(PostingUrl),"Basic",new System.Net.NetworkCredential("username","password") 
myReq.Credentials = CredMCCache; 
     myReq.KeepAlive = true; 
     myReq.UserAgent = "Mozilla/4.0 (compatible; MSIE 7.0; Windows NT 5.1; .NET CLR 1.1.4322; .NET CLR 2.0.50727; .NET CLR 3.0.04506.30; .NET CLR 3.0.04506.648; .NET CLR 3.5.21022)"; 
     myReq.Accept = "*/*"; 
     myReq.Headers.Add("Accept-Language", "en-us"); 
     myReq.Headers.Add("Accept-Encoding", "gzip, deflate"); 
     WebProxy proxyObject = new WebProxy("proxy url with port", false); 
     myReq.Proxy = proxyObject; 
     myReq.Proxy.Credentials = CredentialCache.DefaultNetworkCredentials; 
     myReq.Method = "GET"; 
     HttpWebResponse myResp = null; 


      // Get the response from the conference center 
      myResp = (HttpWebResponse)myReq.GetResponse();

我收到错误在上面的线。任何指针都会有帮助。

你为什么要设置代理，如

myReq.Proxy = proxyObject;

你需要这样做吗？如果你确实要通过公司代理，你不需要为HttpWebRequest设置代理，因为它将从IE中获取设置（如果有的话）。

其次，你是否尝试使用基本身份验证与远程服务器进行身份验证？它看起来像你一样，所以用它来代替标题中的验证详细信息

string authInfo = userName + ":" + userPassword; 
authInfo = Convert.ToBase64String(Encoding.Default.GetBytes(authInfo)); 
myReq.Headers["Authorization"] = "Basic " + authInfo;
