Socket C# in Java umsetzen

[napier]

Hallo

Kann mir jemand bitte diesen c# code in Java umzusetzten. Ich schaffe es einfach nicht ???:L

Danke und Gruss

public static void SendCommand(String command)
{
    try
    {
        StreamWriter clientStreamWriter = null;

        // hardcoded IP Address for now.....
        String onkyoIP = "192.168.1.69";

        int length = command.Length;
        length++;
        int total = length + 16;
        char code = (char)length;

        // build up packet header and rest of command - followed by <CR> (chr(13))
        //
        String line = "ISCP\\x00\\x00\\x00\\x10\\x00\\x00\\x00" + code + "\\x01\\x00\\x00\\x00" + command + "\\x0D";

        // create a TCP Client - hardcoded port too ....
        TcpClient tcpClient = new TcpClient(onkyoIP, 60128);

        //get a network stream from server
        NetworkStream clientSockStream = tcpClient.GetStream();

        // create new writer stream to send the stuff
        clientStreamWriter = new StreamWriter(clientSockStream);

        // send command to receiver
        //
        clientStreamWriter.WriteLine(line);
        clientStreamWriter.Flush();
        clientStreamWriter.Close();
        // close the socket
        tcpClient.Close();
    }
    catch (Exception e)
    {
        // should do something better here... but meh.. it's just for me
        Console.WriteLine(e.StackTrace);
    }
}

Wo ist denn dein Problem er code ist nicht wirklich schwer eigentlich.

 

[Gast2]

Lies dir das hier durch:
Lesson: All About Sockets (The Java™ Tutorials > Custom Networking)
Und ersetze danach alle Klassennamen durch die entsprechenden Javaklasse... fertig 🙂
(nen paar Methoden musste auch noch anpassen 🙁 )

Ok Danke euch für die Hinweise. Funktioniert jetzt.
