Basic TCP Communication Client
suggest changeThis code example creates a TCP client, sends “Hello World” over the socket connection, and then writes the server response to the console before closing the connection.
// Declare Variables
string host = "stackoverflow.com";
int port = 9999;
int timeout = 5000;
// Create TCP client and connect
using (var _client = new TcpClient(host, port))
using (var _netStream = _client.GetStream())
{
_netStream.ReadTimeout = timeout;
// Write a message over the socket
string message = "Hello World!";
byte[] dataToSend = System.Text.Encoding.ASCII.GetBytes(message);
_netStream.Write(dataToSend, 0, dataToSend.Length);
// Read server response
byte[] recvData = new byte[256];
int bytes = _netStream.Read(recvData, 0, recvData.Length);
message = System.Text.Encoding.ASCII.GetString(recvData, 0, bytes);
Console.WriteLine(string.Format("Server: {0}", message));
};// The client and stream will close as control exits the using block (Equivilent but safer than calling Close();
Found a mistake? Have a question or improvement idea?
Let me know.
