我使用 TcpClient 有以下代码

byte[] encbuff = System.Text.Encoding.UTF8.GetBytes("username" + ":" + "password");
        string follow = "track=soccer,twitter";
        byte[] encode_follow = System.Text.Encoding.UTF8.GetBytes(follow);

        using (TcpClient client = new TcpClient())
        {
            string requestString = "POST /1/statuses/filter.json HTTP/1.1\r\n";
            requestString += "Host: stream.twitter.com\r\n";
            requestString += "User-Agent: www.site.com\r\n";
            requestString += "Referer: http://www.site.com\r\n";
            requestString += "Content-Type: application/x-www-form-urlencoded\r\n";
            requestString += "Authorization: " + "Basic " + Convert.ToBase64String(encbuff) + "\r\n";
            requestString += "Content-length: " + follow.Length + "\r\n";
            requestString += "Connection: keep-alive\r\n";
            requestString += "\r\n";
            requestString += follow;
            requestString += "\r\n\r\n";

            client.Connect("stream.twitter.com", 80);
            //client.ReceiveTimeout = 100;
            using (NetworkStream stream = client.GetStream())
            {
                // Send the request.
                StreamWriter writer = new StreamWriter(stream);
                writer.Write(requestString);
                writer.Flush();

                // Process the response.

                    StreamReader rdr = new StreamReader(stream);

                    while (!rdr.EndOfStream)
                    {
                        Console.WriteLine(rdr.ReadLine());
                        Console.WriteLine("IS end: " + rdr.EndOfStream.ToString());
                    }
                }

        }

但是会发生什么是 Console.WriteLine(rdr.ReadLine()); line 将在几秒钟内打印出状态，而不是停止 + 不再在那里打断点，即使它仍然处于连接状态。

它应该做的是继续在控制台中写入状态，因为它是一个保持活动的连接，并且每隔几秒钟就会连续提到几次“Twitter”关键字。

任何想法可能导致此问题？

看一下这个：

public class Program
{
    public static void Main()
    {
        using (var client = new WebClient())
        {
            client.Credentials = new NetworkCredential("username", "password");
            client.OpenReadCompleted += (sender, e) =>
            {
                using (var reader = new StreamReader(e.Result))
                {
                    while (!reader.EndOfStream)
                    {
                        // TODO: feed this to your favorite JSON parser
                        Console.WriteLine(reader.ReadLine());
                    }
                }
            };
            client.OpenReadAsync(new Uri("http://stream.twitter.com/1/statuses/filter.json?track=soccer,twitter"));
        }
        Console.ReadLine();
    }
}

应该让事情变得更容易。
