Mendapatkan alamat Redis Master dari Sentinel C#

Harus melakukannya dengan cara yang sulit, saya meniru perintah redis-cli menggunakan potongan kode berikutnya:(yang tersisa adalah mengurai hasil dari respons)

   public string GetMasterFromSentinel(string sentinelAddress)
    {
        TcpClient server;

        try
        {
            var splittedAddress = sentinelAddress.Split(':');
            server = new TcpClient(splittedAddress[0], splittedAddress[1].ParseInt());
        }
        catch (SocketException)
        {
            _log.Error("Unable to connect to server");
            return string.Empty;
        }
        NetworkStream ns = server.GetStream();
        var payload = new byte[] { 0x2a, 0x32, 0x0d, 0x0a, 0x24, 0x38, 0x0d, 0x0a, 0x73, 0x65, 0x6e, 0x74, 0x69, 0x6e, 0x65, 0x6c, 
                0x0d, 0x0a, 0x24, 0x37, 0x0d, 0x0a, 0x6d, 0x61, 0x73, 0x74, 0x65, 0x72, 0x73, 0x0d, 0x0a };
        ns.Write(payload, 0, payload.Length);
        ns.Flush();
        var data = new byte[1024];
        ns.Read(data, 0, data.Length);
        var recv = ns.Read(data, 0, data.Length);

        ns.Close();
        server.Close();
        return ParseResponse(data);
    }
