visual c# 2005中编写socket网络程序(3)
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.inte.network, 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.inte.network, 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。
