У меня есть два клиент-серверных приложения, я сделал кнопки для получения и отправки значений между двумя приложениями, я хотел бы знать, как получить значение автоматически, если оно изменяется в обоих приложениях и при запуске приложения (Я получаю два значения: bool и int ).
Сервер
public static IPAddress ip = Dns.GetHostEntry("localhost").AddressList[0];
public static TcpListener server = new TcpListener(ip, 8080);
public static TcpClient client = default(TcpClient);
// Stock value interface
public static string val_interface ;
async void buttonConnect_Click(object sender, RoutedEventArgs e)
{
try
{
server.Start();
}
catch (Exception ex)
{
MessageBox.Show(ex.Message);
}
}
private void Button_receiver__Click(object sender, RoutedEventArgs e)
{
// receiver value
client = server.AcceptTcpClient();
byte[] receivedBuffer = new byte[100];
NetworkStream stream = client.GetStream();
stream.Read(receivedBuffer, 0, receivedBuffer.Length);
StringBuilder msg = new StringBuilder();
foreach (byte b in receivedBuffer)
{
string r = msg.Append(Convert.ToChar(b).ToString()).ToString();
// last line
if(receivedBuffer.LastOrDefault().Equals(b))
{
;
r = r.Substring(0, r.Length - 1);
if(r.ToString().Length < 2)
{
if(r.ToString() == "1")
{
val_interface = r.ToString();
}
if(r.ToString() == "0")
{
val_interface = r.ToString();
}
break;
}
else
{
val_interface = r.ToString();
break;
}
}
}
System.Diagnostics.Debug.WriteLine(msg.ToString());
}
private void btn_send_Click(object sender, RoutedEventArgs e)
{
client = server.AcceptTcpClient();
NetworkStream stream = client.GetStream();
string r = val_interface;
int byteCount = Encoding.ASCII.GetByteCount(r);
byte[] sendData = new byte [100];
sendData = Encoding.ASCII.GetBytes(r);
stream.Write(sendData, 0, sendData.Length);
stream.Close();
client.Close();
}
Клиент
public static IPAddress ip = Dns.GetHostEntry("localhost").AddressList[0];
TcpListener server = new TcpListener(ip, 8080);
public static TcpClient client = default(TcpClient);
// information de la connexion
string serverIP = "localhost";
int port = 8080;
// same methods ...
Класс
public class MyClass
{
public static void Send(Socket socket, byte[] buffer, int offset, int size, int timeout)
{
int startTickCount = Environment.TickCount;
int sent = 0; // how many bytes is already sent
do
{
if (Environment.TickCount > startTickCount + timeout)
throw new Exception("Timeout.");
try
{
sent += socket.Send(buffer, offset + sent, size - sent, SocketFlags.None);
}
catch (SocketException ex)
{
if (ex.SocketErrorCode == SocketError.WouldBlock ||
ex.SocketErrorCode == SocketError.IOPending ||
ex.SocketErrorCode == SocketError.NoBufferSpaceAvailable)
{
// socket buffer is probably full, wait and try again
Thread.Sleep(30);
}
else
throw ex; // any serious error occurr
}
} while (sent < size);
}
public static void Receive(Socket socket, byte[] buffer, int offset, int size, int timeout)
{
int startTickCount = Environment.TickCount;
int received = 0; // how many bytes is already received
do
{
if (Environment.TickCount > startTickCount + timeout)
throw new Exception("Timeout.");
try
{
received += socket.Receive(buffer, offset + received, size - received, SocketFlags.None);
}
catch (SocketException ex)
{
if (ex.SocketErrorCode == SocketError.WouldBlock ||
ex.SocketErrorCode == SocketError.IOPending ||
ex.SocketErrorCode == SocketError.NoBufferSpaceAvailable)
{
// socket buffer is probably empty, wait and try again
Thread.Sleep(30);
}
else
throw ex; // any serious error occurr
}
} while (received < size);
}
