综合运用以上阐述的使用Visual C#进行Socket网络程序开发的知识,下面的程序是一个简单的Socket通讯实例,client向server发送一段测试字符串,server接收并显示出来,给予client成功相应。
//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);
Socket c = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp);
c.Connect(ipe);
string sendStr = "hello!This is a socket test";
byte[] bs = Encoding.ASCII.GetBytes(sendStr);
c.Send(bs, bs.Length, 0);
string recvStr = "";
byte[] recvBytes = new byte[1024];
int bytes;
bytes = c.Receive(recvBytes, recvBytes.Length, 0);
recvStr += Encoding.ASCII.GetString(recvBytes, 0, bytes);
Console.WriteLine(recvStr);
c.Close();
}
catch (ArgumentNullException e)
{
Console.WriteLine("ArgumentNullException: {0}", e);
}
catch (SocketException e)
{
Console.WriteLine("SocketException: {0}", e);
}
Console.ReadLine();
}
}
}
//server端
using System;
using System.Text;
using System.IO;
using System.Net;
using System.Net.Sockets;
namespace Project1
{
class Class2
{
static void Main()
{
try
{
int port = 2000;
string host = "127.0.0.1";
IPAddress ip = IPAddress.Parse(host);
IPEndPoint ipe = new IPEndPoint(ip, port);
Socket s = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp);
s.Bind(ipe);
s.Listen(0);
Socket temp = s.Accept();
string recvStr = "";
byte[] recvBytes = new byte[1024];
int bytes;
bytes = temp.Receive(recvBytes, recvBytes.Length, 0);
recvStr += Encoding.ASCII.GetString(recvBytes, 0, bytes);
Console.WriteLine(recvStr);
string sendStr = "Ok!Sucess!";
byte[] bs = Encoding.ASCII.GetBytes(sendStr);
temp.Send(bs, bs.Length, 0);
temp.Shutdown(SocketShutdown.Both);
temp.Close();
s.Shutdown(SocketShutdown.Both);
s.Close();
}
catch (ArgumentNullException e)
{
Console.WriteLine("ArgumentNullException: {0}", e);
}
catch (SocketException e)
{
Console.WriteLine("SocketException: {0}", e);
}
Console.ReadLine();
}
}
}
以上程序在VS Express 2005 .Net2.0环境下测试通过。
