当WebClient下载字符串时，底层连接异常关闭

我也有同样的错误。

你可以添加用户代理到你的httpRequest

request.UserAgent = "Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/535.2 (KHTML, like Gecko) Chrome/15.0.874.121 Safari/535.2";

好的，我得到了这一切修复&工作!

static void Main(string[] args)
{
    Uri url = new Uri(@"http://content.warframe.com/dynamic/rss.php");
    HttpWebRequest request = (HttpWebRequest)WebRequest.Create(url);
    // MAGIC LINE GOES HERE '/
    request.AutomaticDecompression = DecompressionMethods.GZip | DecompressionMethods.Deflate;
    // Assign the response object of HttpWebRequest to a HttpWebResponse variable.
    using (HttpWebResponse response = (HttpWebResponse)request.GetResponse())
    {
        using (Stream streamResponse = response.GetResponseStream())
        {
            using (StreamReader streamRead = new StreamReader(streamResponse))
            {
                Char[] readBuff = new Char[2000];
                int count = streamRead.Read(readBuff, 0, 2000);
                while (count > 0)
                {
                    String outputData = new String(readBuff, 0, count);
                    Console.Write(outputData);
                    count = streamRead.Read(readBuff, 0, 2000);
                }
            }
        }
    }
    Console.ReadKey();
}

除了不使用WebClient。下载字符串方法我必须添加解压行

request.AutomaticDecompression = DecompressionMethods.GZip | DecompressionMethods.Deflate;

感谢提示(特别是小提琴手之一，解码按钮节省了我的时间来找到什么是错的)

检查这个答案:

. .底层连接已关闭:在接收

所以这可能对你有用:

var webRequest = (HttpWebRequest)HttpWebRequest.Create(@"http://content.warframe.com/dynamic/rss.php");
webRequest.KeepAlive = false;
var resp = webRequest.GetResponse();        

编辑:

你是对的，检查一下:http://msdn.microsoft.com/cs-cz/library/system.net.httpwebrequest.keepalive%28v=vs.110%29.aspx

下面是打印接收到的响应内容的工作代码:

    static void Main(string[] args)
    {
          // Create a new HttpWebRequest object.Make sure that 
          // a default proxy is set if you are behind a firewall.
          HttpWebRequest myHttpWebRequest1 =
            (HttpWebRequest)WebRequest.Create(@"http://content.warframe.com/dynamic/rss.php");
          myHttpWebRequest1.KeepAlive=false;
          // Assign the response object of HttpWebRequest to a HttpWebResponse variable.
          HttpWebResponse myHttpWebResponse1 = 
            (HttpWebResponse)myHttpWebRequest1.GetResponse();
          Console.WriteLine("'nThe HTTP request Headers for the first request are: 'n{0}", myHttpWebRequest1.Headers);
          Stream streamResponse = myHttpWebResponse1.GetResponseStream();
          StreamReader streamRead = new StreamReader(streamResponse);
          Char[] readBuff = new Char[256];
          int count = streamRead.Read(readBuff, 0, 256);
          Console.WriteLine("The contents of the Html page are.......'n");
          while (count > 0)
          {
              String outputData = new String(readBuff, 0, count);
              Console.Write(outputData);
              count = streamRead.Read(readBuff, 0, 256);
          }
          Console.WriteLine();
          // Close the Stream object.
          streamResponse.Close();
          streamRead.Close();
          Console.ReadKey();
    }
