方法1:Socket(套接字)编程(Tcp)
TCPServer代码
using System;
using System.Net;
using System.Net.Sockets;
using System.Text;
namespace TcpServer
{
class Program
{
static void Main(string[] args)
{
//建立连接
Socket tcpServer = new Socket(AddressFamily.InterNetwork,SocketType.Stream,ProtocolType.Tcp);//使用IPV4插口,流类型进行数据传输,使用TCP协议
IPAddress ipAddress = new IPAddress(new byte[] { 192, 168, 42, 104 });//ip地址
IPEndPoint ipEndPoint = new IPEndPoint(ipAddress, 7788);//端口号
tcpServer.Bind(ipEndPoint);
tcpServer.Listen(100);
//检测客户端的连接
Console.WriteLine("服务器已启动");
Socket client = tcpServer.Accept();
Console.WriteLine("一个客户端连接过来了");
//接收到消息并输出
byte []data =new byte[1024];
int length = client.Receive(data);
string message = Encoding.UTF8.GetString(data, 0, length);
Console.WriteLine("接收到客户端的消息:"+message);
//关闭连接
client.Close();
tcpServer.Close();
}
}
}
TCPClient代码
using System;
using System.Net;
using System.Net.Sockets;
using System.Text;
namespace TcpClient
{
class Program
{
static void Main(string[] args)
{
//建立连接
Socket tcpClient = new Socket(AddressFamily.InterNetwork,SocketType.Stream,ProtocolType.Tcp);
IPAddress ipAddress = new IPAddress(new byte[] { 192, 168, 42, 104 });//ip地址
IPEndPoint ipEndPoint = new IPEndPoint(ipAddress, 7788);//端口号
tcpClient.Connect(ipEndPoint);
Console.WriteLine("连接到服务器...");
//tcpClient.Receive(new byte[]{22});
//发送消息
string message = "客户端发出了一条消息";
tcpClient.Send(Encoding.UTF8.GetBytes(message));
//关闭连接
tcpClient.Close();
}
}
}
方法2:Socket(套接字)编程(Udp)
UdpServer代码
using System;
using System.Net;
using System.Net.Sockets;
using System.Text;
namespace UDPServer
{
class Program
{
static void Main(string[] args)
{
//建立连接
Socket Udpserver = new Socket(AddressFamily.InterNetwork,SocketType.Dgram,ProtocolType.Udp);//连接,socket类型,协议类型
IPAddress ipAddress = new IPAddress(new byte[] { 192, 168, 42, 104 });//ip地址
IPEndPoint ipEndPoint = new IPEndPoint(ipAddress, 7788);//端口号
Udpserver.Bind(ipEndPoint);
Console.WriteLine("UDP服务器端已开启...");
//接收数据
IPEndPoint ipep = new IPEndPoint(IPAddress.Any, 0);
EndPoint ep = (EndPoint) ipep;
byte[] data = new byte[1024];
int length = Udpserver.ReceiveFrom(data,ref ep);
Console.WriteLine("接收到的数据:"+ Encoding.UTF8.GetString(data, 0, length));
//关闭连接
Udpserver.Close();
}
}
}
UdpClient代码
using System;
using System.Net;
using System.Net.Sockets;
using System.Text;
namespace UdpClient
{
class Program
{
static void Main(string[] args)
{
//建立连接
Socket UdpClient = new Socket(AddressFamily.InterNetwork, SocketType.Dgram, ProtocolType.Udp);//连接,socket类型,协议类型
IPAddress ipAddress = new IPAddress(new byte[] { 192, 168, 42, 104 });//ip地址
IPEndPoint ipEndPoint = new IPEndPoint(ipAddress, 7788);//端口号
//发送数据
byte[] data = Encoding.UTF8.GetBytes("你好,UDP客户端上线了");
UdpClient.SendTo(data, ipEndPoint);
//关闭连接
UdpClient.Close();
}
}
}
