UDP比TCP通信,就相对简单多了
先上代码,建立2个控制台程序,分别为SEUDP1,SEUDP2,其中SEUDP1中增加一个类
class UDP
{
private IUdpEngine udpServerEngine;
public UDP(int port)
{
this.udpServerEngine = NetworkEngineFactory.CreateUdpEngine();
this.udpServerEngine.Port = port;
this.udpServerEngine.LogFilePath = @"C:\";
this.udpServerEngine.MessageReceived += udpServerEngine_MessageReceived;
}
private void udpServerEngine_MessageReceived(IPEndPoint obj1, byte[] obj2)
{
string msg = System.Text.Encoding.UTF8.GetString(obj2);
Console.WriteLine("Get message from [{0}]:{1}", obj1.ToString(), msg);
}
public void Start()
{
this.udpServerEngine.Initialize();
}
public void Send(string ip, int port, byte[] msg)
{
IPEndPoint iep = new IPEndPoint(IPAddress.Parse(ip), port);
this. udpServerEngine.SendMessage(iep, msg);
}
public void Send(string ip, int port, string msg)
{
byte[] bs = System.Text.Encoding.UTF8.GetBytes(msg);
this.Send(ip, port, bs);
}
}
同时,在SEUPD2中增加这个类的链接,然后就都可以使用了
SEUPD1中的Main函数
static void Main(string[] args)
{
UDP sender = );
sender.Start();
while (true)
{
string msg = Console.ReadLine();
sender.Send(, msg);
}
}
SEUPD2中的Main函数
static void Main(string[] args)
{
UDP sender = );
sender.Start();
while (true)
{
string msg = Console.ReadLine();
sender.Send(, msg);
}
}
启动SEUPD1和SEUDP2,在控制台敲任意字符,都能发送到对方,并且打印出来.
注意:
- UDP是没有客户端和服务端之分的,这一点和tcp的区别最明显
- 对报文没有那么多控制,(我说的控制,不是因为我没定义报文类,)
- 非面向连接,发送就完成,不管身后事
