以下函数将从Twitter firehose下载第一个X消息,但看起来像WebResponse块并且从不退出该函数:
public void GetStatusesFromStream(string username, string password, int nMessageCount)
{
WebRequest request = WebRequest.Create("http://stream.twitter.com/1/statuses/sample.json");
request.Credentials = new NetworkCredential(username, password);
using (WebResponse response = request.GetResponse())
{
using (var stream = response.GetResponseStream())
{
using (var reader = new StreamReader(stream))
{
while (!reader.EndOfStream)
{
Console.WriteLine(reader.ReadLine());
if (nMessageCount-- < 0)
break;
}
Console.WriteLine("Start iDispose");
}
Console.WriteLine("Never gets here!!!");
}
}
Console.WriteLine("Done - press a key to exit");
Console.ReadLine();
}
但以下工作正常:
public void GetStatusesFromStreamOK(string username, string password, int nMessageCount)
{
byte[] encbuff = System.Text.Encoding.UTF8.GetBytes(username + ":" + password);
//request.Headers.Add("Authorization", "Basic " + Convert.ToBase64String(encbuff));
string requestString = "GET /1/statuses/sample.json HTTP/1.1\r\n";
requestString += "Authorization: " + "Basic " + Convert.ToBase64String(encbuff) + "\r\n";
requestString += "Host: stream.twitter.com\r\n";
requestString += "Connection: keep-alive\r\n";
requestString += "\r\n";
using (TcpClient client = new TcpClient())
{
client.Connect("stream.twitter.com", 80);
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());
if (nMessageCount-- < 0)
break;
}
}
}
Console.WriteLine("Done - press a key to exit");
Console.ReadLine();
}
我做错了什么?

将WebRequest
投射为HttpWebRequest
,然后在休息电话request.Abort()

看起来它与处理过程或“使用”...
有关以下代码可以正常工作(没有“使用”语句):
public static void GetStatusesFromStream(string username, string password, int nMessageCount)
{
WebRequest request = WebRequest.Create("http://stream.twitter.com/1/statuses/sample.json");
request.Credentials = new NetworkCredential(username, password);
WebResponse response = request.GetResponse();
{
var stream = response.GetResponseStream();
{
var reader = new StreamReader(stream);
{
while (!reader.EndOfStream)
{
Console.WriteLine(reader.ReadLine());
if (nMessageCount-- < 0)
break;
}
}
Console.WriteLine("Never gets here!!!");
}
}
Console.WriteLine("Done - press a key to exit");
Console.ReadLine();
}
