C#UDP通信最简单一例

接收端：

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Net;
using System.Net.Sockets;

namespace Server
{
    class Program
    {
        static void Main(string[] args)
        {
            var udpReceiver = new UdpClient(8112, AddressFamily.InterNetwork);
            IPEndPoint remoteHost = null;
            var data = udpReceiver.Receive(ref remoteHost);
            var msg = Encoding.Default.GetString(data);
            Console.WriteLine(msg);
            Console.In.ReadLine();
        }
    }
}

发送端：

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Net.Sockets;
using System.Net;

namespace Client
{
    class Program
    {
        static void Main(string[] args)
        {
            var msg = Console.In.ReadLine();
            var udpClient = new UdpClient(8110);
            var udpRemote = new IPEndPoint(IPAddress.Parse("127.0.0.1"), 8112);
            var data = Encoding.Default.GetBytes(msg);
            udpClient.Send(data,data.Length,udpRemote);
        }
    }
}
