.NET相當於Java的BufferedReader

Question

我有Java代碼

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
}

如果您需要完整的代碼，請粘貼。

我想將其重寫為C＃

但我不知道這相當於BufferReader。 我有套接字，我想從套接字InputStream中讀取（使用UTF8）

謝謝。

這樣的事情應該可以幫助您，盡管我確定我會遺漏大量異常條件處理和一些小事情，例如，正常關閉服務器。

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() ;
      }
    }

  }

}

如果要緩沖流，只需用BufferedStream裝飾NetworkStream實例：

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() ;
}

這取決於您想要什么。 BufferedReader緩沖來自另一個讀取器的數據。 如果只希望緩沖讀取，則可以使用StreamReader之類的方法，具體取決於您想要讀取數據的方式。

類似以下內容將是可比較的。

using(StreamReader reader = new StreamReader(Socket.GetStream(), Encoding.UTF8)) {
    while(reader.Peek() >= 0) {
        Console.WriteLine(reader.ReadLine()); // or something...
    }
}
