SimpleTcp

A simple-to-use TCP server and client library.

Usage

Start Tcp Server

RawTcpServer tcpServer = new RawTcpServer();
tcpServer.Start(5000);

Can use Event Handlers

RawTcpServer tcpServer = new RawTcpServer();
tcpServer.ClientConnected += ClientConnected;
tcpServer.ClientDisconnected += ClientDisconnected;
tcpServer.DataReceived += DataReceived;

Connect to Tcp Server

RawTcpClient tcpClient = new RawTcpClient();
tcpClient.Connect("127.0.0.1", 5000);

Can use Event Handlers

RawTcpClient tcpClient = new RawTcpClient();
tcpClient.Connected += Connected;
tcpClient.Disconnected += Disconnected;
tcpClient.DataReceived += DataReceived;

Examples

Echo Server

static void Main(string[] args)
{
    using (RawTcpServer tcpServer = new RawTcpServer())
    {
        tcpServer.ClientConnected += (sender, e) =>
            Console.WriteLine($"[{e}]: Connected"); // new client connected
        tcpServer.ClientDisconnected += (sender, e) =>
            Console.WriteLine($"[{e}]: Disconnected"); // client disconnected
        tcpServer.DataReceived += (sender, e) =>
        {
            byte[] readBytes = e.Client.ReadExisting(); // read all data
            string dataString = readBytes.Aggregate( // data to hex string
                new StringBuilder(32),
                (stringBuilder, data) => stringBuilder.Append($" 0x{data.ToString("X2")}")
                ).ToString().Trim();

            Console.WriteLine($"[{e.Client}]: {dataString}");

            e.Client.Write(readBytes, 0, readBytes.Length); // return same data
        };

        try
        {
            tcpServer.Start(5000);
            Console.WriteLine("Listening for connections...");
        }
        catch (Exception ex)
        {
            Console.WriteLine(ex);
        }

        Console.ReadLine();
    }
}

Echo Client

                Console.WriteLine($"DataReceived: {Encoding.ASCII.GetString(readBytes)}");
            }
        };

        try

Packet Echo Server

The size of the received data is received without being cut off.

static void Main(string[] args)
{
  using (PacketTcpServer tcpServer = new PacketTcpServer())
  {
      tcpServer.ClientConnected += (sender, e) =>
          Console.WriteLine($"[{e}]: Connected"); // new client connected
      tcpServer.ClientDisconnected += (sender, e) =>
          Console.WriteLine($"[{e}]: Disconnected"); // client disconnected
      tcpServer.PacketReceived += (sender, e) =>
      {
          if (sender is PacketTcpServer packetTcpServer)
          {
              Console.WriteLine($"[{e.Packet.IPEndPoint}]: PacketReceived (PacketLength: {e.Packet.PacketData.Length})");
              packetTcpServer.WritePacket(e.Packet.TcpClient, e.Packet.PacketData); // return same packet
          }
      };

      try
      {
          tcpServer.Start(5000);
          Console.WriteLine("Listening for connections...");
      }
      catch (Exception ex)
      {
          Console.WriteLine(ex);
      }

      Console.ReadLine();
  }
}
