自动处理了底层通信的很多东西封装的很好，使用方便 ，提供了丰富的事件支持

//服务端

//显示消息
delegate void ShowMsg(int connid, string msg);

public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}

HPSocketCS.TcpServer tcpServer = new HPSocketCS.TcpServer()
{
IpAddress = "192.168.3.61",
Port = 8858
};

private void Form1_Load(object sender, EventArgs e)
{
tcpServer.OnAccept += httpServer_OnAccept;
tcpServer.OnReceive += httpServer_OnReceive;
}

//启动
private void button1_Click(object sender, EventArgs e)
{
textBox1.Text += tcpServer.IpAddress + ":" + tcpServer.Port + " 开始监听： ";
tcpServer.Start();
}

/// <summary>
/// 监听到连接
/// </summary>
/// <param name="connId"></param>
/// <param name="pClient"></param>
/// <returns></returns>
public HandleResult httpServer_OnAccept(IntPtr connId, IntPtr pClient)
{
ShowMsg showMsg = new ShowMsg((connid, msg) => { textBox1.Text += string.Format("客户端{0}：{1} ", connid, msg); });
this.Invoke(showMsg, new object[] { connId.ToInt32(), "我上线了..." });
return HandleResult.Ok;
}

/// <summary>

/// </summary>
/// <param name="connId"></param>
/// <param name="bytes"></param>
/// <returns></returns>
public HandleResult httpServer_OnReceive(IntPtr connId, byte[] bytes)
{
ShowMsg showMsg = new ShowMsg((connid, msg) => { textBox1.Text += string.Format("客户端{0}说：{1} ", connid, msg); });
this.Invoke(showMsg, new object[] { connId.ToInt32(), Encoding.Default.GetString(bytes) });
return HandleResult.Ok;
}

}

//客户端

public partial class Form1 : Form
{
HPSocketCS.TcpClient tcpClient;
public Form1()
{
InitializeComponent();
}

private void Form1_Load(object sender, EventArgs e)
{
tcpClient = new HPSocketCS.TcpClient();
bool connected = tcpClient.Connect("192.168.3.61", 8858);
if (connected)
{
textBox1.Text += (tcpClient.ConnectionId + ":已经连接");
}
}

private void button1_Click(object sender, EventArgs e)
{
string msg = textBox2.Text.Trim();
var bytes=Encoding.Default.GetBytes(msg);
bool sended = tcpClient.Send(bytes, 0, bytes.Length);
