下面看一個完整的例子,client向server發送一段測試字符串,server接收並顯示出來,給予clIEnt成功響應。
//clIEnt端
using System;
using System.Text;
using System.IO;
using System.Net;
using System.Net.Sockets;
namespace socketsample
{
class Class1
{
static void Main()
{
try
{
int port = 2000;
string host = "127.0.0.1";
IPAddress ip = IPAddress.Parse(host);
IPEndPoint ipe = new IPEndPoint(ip, port);//把ip和端口轉化為IPEndPoint實例
Socket c = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp);//創建一個Socket
Console.WriteLine("Conneting...");
c.Connect(ipe);//連接到服務器
string sendStr = "hello!This is a socket test";
byte[] bs = Encoding.ASCII.GetBytes(sendStr);
Console.WriteLine("Send Message");
c.Send(bs, bs.Length, 0);//發送測試信息
string recvStr = "";
byte[] recvBytes = new byte[1024];
int bytes;
bytes = c.Receive(recvBytes, recvBytes.Length, 0);//從服務器端接受返回信息
recvStr += Encoding.ASCII.GetString(recvBytes, 0, bytes);
Console.WriteLine("ClIEnt Get Message:{0}", recvStr);//顯示服務器返回信息
c.Close();
}
catch (ArgumentNullException e)
{
Console.WriteLine("ArgumentNullException: {0}", e);
}
catch (SocketException e)
{
Console.WriteLine("SocketException: {0}", e);
}
Console.WriteLine("Press Enter to Exit");
Console.ReadLine();
}
}
}
