一、服务端
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}
private void button1_Click(object sender, EventArgs e)
{
MyServer appServer = new MyServer();
var se = new SuperSocket.SocketBase.Config.ServerConfig();

appServer.NewRequestReceived += appServer_NewRequestReceived;
}

string key = requestInfo.Key;
switch (key)

case "1":

break;
case "2":
Console.WriteLine("Get image");
break;
default:
Console.WriteLine("Get unknown message.");
break;
}
}
}
public class MyServer : AppServer<MySession, BinaryRequestInfo>
{
public MyServer()

}
}

二、客户端
public class MyTcpClient
{
private System.Net.Sockets.TcpClient tcpClient;
public MyTcpClient(string ip, int port)
{
tcpClient = new System.Net.Sockets.TcpClient(ip, port);
byte[] recData = new byte[1024];
Action a = new Action(() =>
{
while (true)
{
tcpClient.Client.Receive(recData);
var msg = System.Text.Encoding.UTF8.GetString(recData);
Console.WriteLine(msg);
}
});
a.BeginInvoke(null, null);
}
public void Send(string message)
{
var data = System.Text.Encoding.UTF8.GetBytes(message);
tcpClient.Client.Send(data);
}
public void Send(byte[] message)
{
tcpClient.Client.Send(message);
}
}
public class SuperSocketMessage
{
public byte[] Start;//4个字节
public ushort Type;//2个字节, 1表示文字消息,2表示图片消息,其他表示未知,不能解析
public int Len;//4个字节
public string Message;//文本信息
public byte[] Tail;//消息结尾
public SuperSocketMessage()
{
Start = new byte[] { 0xFF, 0xFF, 0xFF, 0xFF };
Tail = new byte[] { 0x1F, 0x1F, 0x1F, 0x1F };
}
public byte[] ToBytes()
{
List<byte> list = new List<byte>();
list.AddRange(Start);
var t = BitConverter.GetBytes(Type);
list.AddRange(t);
var t3 = System.Text.Encoding.UTF8.GetBytes(Message);
var t2 = BitConverter.GetBytes(t3.Length);//注意,这里不是Message.Length,而是Message转化成字节数组后的Lenght
list.AddRange(t2);
list.AddRange(t3);
return list.ToArray();
}
}
private void button1_Click(object sender, EventArgs e)
{
MyTcpClient c = new MyTcpClient("127.0.0.1", 2020);
SuperSocketMessage msg = new SuperSocketMessage();
msg.Type = 1;
msg.Message = "aaa"; ;
byte[] bytes = msg.ToBytes();
string hexString = BitConverter.ToString(bytes).Replace("-", "");
c.Send(msg.ToBytes());
}
