error of reading data in socket programming

I get a lot of data in a few minute. but then I receive error.

below is all my cod:
namespace consolprogramming
{
class Program
{
static void Main(string[] args)
{
//byte[] msg = Encoding.UTF8.GetBytes("thanks ...");
byte[] bytes = new byte[512];
try
{

XmlDocument DOC = new XmlDocument();

string path = Path.GetDirectoryName(Assembly.GetExecutingAssembly().Location) + @"\k.xml";

//DOC.Load(path);

// XmlNode root;

DataSet ds = new DataSet("kDs");
IPHostEntry ipHost = Dns.GetHostEntry("");
// Gets first IP address associated with a localhost
IPAddress add = ipHost.AddressList[3];


TcpListener tcpListener = new TcpListener(add, 6000);
tcpListener.Start();

Console.WriteLine("Waiting for a connection...");


ds.Namespace = "sample";
DataTable stdTable = new DataTable("azmon");
DataColumn col1 = new DataColumn("data");
stdTable.Columns.Add(col1);
ds.Tables.Add(stdTable);

//Add azmon Data to the table




TcpClient tcpClient = tcpListener.AcceptTcpClient();


NetworkStream stream = tcpClient.GetStream();
DataRow newRow;
String data = null;
while (true)
{
int i;
//try
//{
while ((i = stream.Read(bytes, 0, bytes.Length)) != 0)
{
// Translate data bytes to a ASCII string.
data = System.Text.Encoding.ASCII.GetString(bytes, 0, i);
Console.WriteLine("Received: {0}", data);

// Process the data sent by the client.
//data = data.ToUpper();

byte[] msg = System.Text.Encoding.ASCII.GetBytes("thanks");

// Send back a response.
stream.Write(msg, 0, msg.Length);
Console.WriteLine("Sent: {0}", "thanks");

newRow = stdTable.NewRow();
newRow["data"] = data;

stdTable.Rows.Add(newRow);

ds.AcceptChanges();
ds.WriteXml(path);
}
//}
//catch (IOException ioe)
//{

//}

// Shutdown and end connection
tcpClient.Close();
}

}
catch (SocketException e)
{
Console.WriteLine("{0} Error code: {1}.", e.Message, e.ErrorCode);
Console.ReadKey();
}
}

}
}
1) I have a adhoc network with 2 system. one is a hardware that sends data in every 10 ms. I dont want to have limitation in sending data. 2) every data is 512 byte. i receive a lot of number of this every 512 byte but after period of time i do not receive rest of them. and get error. 3)where should i close my connection?

4) I Check the line number where the exception occurred. It failing on the Read()
