socket programming send recieve string from server to client

Question

Hi,

 

I have a question about socket programming. i need a server/client solution where i'm able to send text string from the server to the client and from client to the server.

 

i have figured out this:

 

Server:

 

static void Main(string[] args)

{

Socket sck = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp);

sck.Bind(new IPEndPoint(0, 1994));

sck.Listen(0);

Socket acc = sck.Accept();

while (true)

{

Console.Write("Write a message");

string msg = Console.ReadLine();

byte[] msgBuffer = Encoding.Default.GetBytes(msg);

acc.Send(msgBuffer, 0, msgBuffer.Length, 0);

byte[] buffer = new byte[255];

int rec = acc.Receive(buffer, 0, buffer.Length, 0);

Array.Resize(ref buffer, rec);

Console.WriteLine("Recived: {0}", Encoding.Default.GetString(buffer));

}

}

 

Client:

 

static void Main(string[] args)

{

Socket sck = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp);

IPEndPoint endPoint = new IPEndPoint(IPAddress.Parse("192.168.1.61"), 1994);

sck.Connect(endPoint);

while (true)

{

Console.Write("Skriv en besked: ");

string msg = Console.ReadLine();

byte[] msgBuffer = Encoding.Default.GetBytes(msg);

sck.Send(msgBuffer, 0, msgBuffer.Length, 0);

byte[] buffer = new byte[255];

int rec = sck.Receive(buffer, 0, buffer.Length, 0);

Array.Resize(ref buffer, rec);

Console.WriteLine("Recived: {0}", Encoding.Default.GetString(buffer));

}

Console.Read();

}

 

 

it dosent work correctly, when the client connects i cannot send a message before the client have sended to me. and when the client have sended a message to me, the client is able to see me message from before.

 

hope that not too confusing /:
