C# udp协议的同步通讯

服务器

class UdpSever
{
IPEndPoint ip;
Socket socket;

public struct App
{
public EndPoint endPoint; //客户端的ip
public string text;
}
public UdpSever()
{
ip = new IPEndPoint(IPAddress.Any, 2333);//设置ip和端口
socket = new Socket(AddressFamily.InterNetwork, SocketType.Dgram, ProtocolType.Udp);
socket.Bind(ip);
}

public App GetApp()
{
byte[] data = new byte[1024];
App app = new App();
app.endPoint = new IPEndPoint(IPAddress.Any, 0);
int recv = socket.ReceiveFrom(data, ref app.endPoint);
app.text = Encoding.Default.GetString(data, 0, recv);
return app;
}

public void Send(App app, string text)
{
byte[] data = Encoding.Default.GetBytes(text);
socket.SendTo(data, data.Length, SocketFlags.None, app.endPoint);
}
}

客户端

class UdpApp
{
IPEndPoint ip;
Socket socket;

public UdpApp()
{
ip = new IPEndPoint(IPAddress.Parse("127.0.0.1"), 2333);//设置ip和端口
socket = new Socket(AddressFamily.InterNetwork, SocketType.Dgram, ProtocolType.Udp);
}

public string Sent(string text)
{
byte[] data = new byte[1024];
data = Encoding.Default.GetBytes(text);
socket.SendTo(data, data.Length, SocketFlags.None, ip);
IPEndPoint sender = new IPEndPoint(IPAddress.Any, 0);
EndPoint Remote = sender;

data = new byte[1024];
int recv = socket.ReceiveFrom(data, ref Remote);
return Encoding.Default.GetString(data, 0, recv);
}
