socket 服務器端：
1.創建socket
Socket tcpClient = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp);//三個參數分別為枚舉類型（網絡），Socket類型，協議
2.綁定ip和端口號
IPAddress ipAddress = new IPAddress(new byte[] {192,168,119,1});
EndPoint point =new IPEndPoint(ipAddress,8811);
tcpServer .Bind(point);//綁定方法Bind()，IPEndPoint()封裝ip和端口
3.開始監聽
tcpServer.Listen(100);//參數為最大連接數
4.接收客戶端
Socket clientSocket= tcpServer.Accept();
5.給客戶端發信息
string message = "hello welcome!";
byte[] date = Encoding.UTF8.GetBytes(message);//Encoding()轉碼
clientSocket.Send(date);
6.接收客戶端信息
byte[] date2=new byte[1024];
int length = clientSocket.Receive(date2);
string message2 = Encoding.UTF8.GetString(date2, 0, length);
Console.WriteLine("客戶端發信息過來："+message2);
代碼：
using System;
using System.Collections.Generic;
using System.Linq;
using System.Net;
using System.Net.Sockets;
using System.Text;
namespace SocketServer
{
class Program
{
static void Main(string[] args)
{
Socket tcpServer =new Socket( AddressFamily.InterNetwork,SocketType.Stream, ProtocolType.Tcp);
IPAddress ipAddress = new IPAddress(new byte[] {192,168,191,1});
EndPoint point =new IPEndPoint(ipAddress,8811);
tcpServer .Bind(point);
tcpServer.Listen(100);
Console.WriteLine("開始監聽");
Socket clientSocket= tcpServer.Accept();
Console.WriteLine("一個客戶端鏈接過來");
string message = "hello welcome!";
byte[] date = Encoding.UTF8.GetBytes(message);
clientSocket.Send(date);
byte[] date2=new byte[1024];
int length = clientSocket.Receive(date2);
string message2 = Encoding.UTF8.GetString(date2, 0, length);
Console.WriteLine("客戶端發信息過來："+message2);
Console.ReadKey();
}
}
}
socket 客戶端
1.創建socket
2.發起請求
tcpClient.Connect();
3.接收服務器端信息
4.向服務器端發信息
代碼：
using System;
using System.Collections.Generic;
using System.Linq;
using System.Net;
using System.Net.Sockets;
using System.Text;
namespace SocketClient
{
class Program
{
static void Main(string[] args)
{
Socket tcpClient = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp);
IPAddress ipAddress=new IPAddress(new byte[]{192,168,191,1});
EndPoint point =new IPEndPoint(ipAddress,8811);
tcpClient.Connect(point);
byte[] date = new byte[1024];
int length= tcpClient.Receive(date);
string message = Encoding.UTF8.GetString(date, 0, length);
Console.WriteLine("服務器端發過來的信息："+message);
string message2 = Console.ReadLine();
tcpClient.Send(Encoding.UTF8.GetBytes(message2));
Console.ReadKey();
}
}
}
