.NET相当于Java的BufferedReader

Question

我用Java编写代码

public void read() throws IOException {
    BufferedReader in = new BufferedReader(new InputStreamReader(this.socket.getInputStream(), "UTF8"));
    String requestURL = null;
    Vector property = new Vector();
    String line;
       //MORE OF CODE
}

如果您需要完整代码,请粘贴.

我想把它改写成C#

但我不知道哪个等同于BufferReader.我有socket,我想从套接字InputStream读取(使用UTF8)

谢谢.

这样的事情应该对你有所帮助,虽然我确信我缺少一些特殊的条件处理和一些小问题,比如哦,优雅的服务器关闭.

static void Main( string[] args )
{
  string      localMachineName    = Dns.GetHostName() ;
  IPHostEntry localMachineInfo    = Dns.GetHostEntry( localMachineName ) ;
  IPAddress   localMachineAddress = localMachineInfo.AddressList[0] ;
  IPEndPoint  localEndPoint       = new IPEndPoint( localMachineAddress , PORT_NUMBER ) ;

  using ( Socket server = new Socket( localEndPoint.AddressFamily , SocketType.Stream , ProtocolType.Tcp ) )
  {
    server.Bind(   localEndPoint                    ) ;
    server.Listen( PENDING_CONNECTIONS_QUEUE_LENGTH ) ;

    while ( true )
    {
      using ( Socket        connection       = server.Accept()                                         )
      using ( NetworkStream connectionStream = new NetworkStream( connection       , FileAccess.Read , false ) )
      using ( TextReader    connectionReader = new StreamReader(  connectionStream , Encoding.UTF8  ) )
      {
        IPEndPoint remoteEndpoint = (IPEndPoint) connection.RemoteEndPoint ;

        string line ;
        while ( null != (line=connectionReader.ReadLine()) )
        {
          line = line.Trim() ;
          Console.WriteLine( "Client says: {0}" , line ) ;
          if ( string.Equals( "exit"     , line , StringComparison.InvariantCultureIgnoreCase ) ) break ;
          if ( string.Equals( "quit"     , line , StringComparison.InvariantCultureIgnoreCase ) ) break ;
          if ( string.Equals( "goodbye"  , line , StringComparison.InvariantCultureIgnoreCase ) ) break ;
          if ( string.Equals( "good-bye" , line , StringComparison.InvariantCultureIgnoreCase ) ) break ;
        }

        connection.Shutdown( SocketShutdown.Both ) ;
        connection.Close() ;
      }
    }

  }

}

如果要缓冲流,只需使用以下命令装饰NetworkStream实例BufferedStream:

using ( Socket     connection       = server.Accept()                                                            )
using ( Stream     connectionStream = new NetworkStream( connection       , FileAccess.Read , false            ) )
using ( TextReader connectionReader = new StreamReader( new BufferedStream( connectionStream ) , Encoding.UTF8 ) )
{
  IPEndPoint remoteEndpoint = (IPEndPoint) connection.RemoteEndPoint ;

  string line ;
  while ( null != (line=connectionReader.ReadLine()) )
  {
    line = line.Trim() ;
    Console.WriteLine( "Client says: {0}" , line ) ;
    if ( string.Equals( "exit"     , line , StringComparison.InvariantCultureIgnoreCase ) ) break ;
    if ( string.Equals( "quit"     , line , StringComparison.InvariantCultureIgnoreCase ) ) break ;
    if ( string.Equals( "goodbye"  , line , StringComparison.InvariantCultureIgnoreCase ) ) break ;
    if ( string.Equals( "good-bye" , line , StringComparison.InvariantCultureIgnoreCase ) ) break ;
  }

  connection.Shutdown( SocketShutdown.Both ) ;
  connection.Close() ;
}
