Examples of use

For the examples, an online service tcpbin.com is used that returns all sent packages.

Simple example send and receive data

void OnDataReceived(byte[] receivedData)
{
}

using var cancellationTokenSource = new CancellationTokenSource(1000);

using var tcpClient = new TcpClient();
tcpClient.DataReceived += OnDataReceived;
await tcpClient.ConnectAsync("tcpbin.com", 4242, cancellationTokenSource.Token);
await tcpClient.SendAsync(new byte[] { 0x01, 0x0A });
await Task.Delay(400);
tcpClient.Disconnect();
tcpClient.DataReceived -= OnDataReceived;
