程序|浏览器

今天早上 我写了一篇 用socket 做的 时间服务器，当时我说准备用一段时间作个不需要客户端接收数据
而是用 浏览器 接收数据的程序，很顺利，一天的时间 我就做好了：）
闲话不说，先看程序。。。

this.s = s;

}

NetworkStream ns = new NetworkStream(s, FileAccess.ReadWrite);
bs = new BufferedStream(ns);
sr = new StreamReader(bs);
sw = new StreamWriter(bs);
writeURL();
s.Shutdown(SocketShutdown.SdBoth);
ns.Close();
}

try {
writeSuccess();
} catch(FileNotFoundException) {
writeFailure();
sw.WriteLine("File not found: " + url);
}
sw.Flush();
}

public void writeSuccess() {

sw.WriteLine("Content-Type: text/html");
sw.WriteLine("");

String strDateLine;
DateTime now;
now = DateTime.Now;
strDateLine = now.ToShortDateString() + " " + now.ToLongTimeString();
sw.WriteLine(strDateLine);
}

}
}
