本文使用的开发环境是vs2017及dotnet4.0，写此随笔的目的是给自己及新开发人员作为参考，
本例子比较简单，使用的是控制台程序开发，若需要使用该软件作为演示，必须先运行服务端，再运行客户端。
因为是首次接触该方面的知识，写得比较简陋，如有更好的建议，请提出，谢谢！
一、编写服务器端代码，如下：
using system;
using system.text;
using system.net;
using system.net.sockets;
using system.threading.tasks;
namespace chatserver
{
class program
{
static void main(string[] args)
{
bool cancel = false;
byte[] buffer = new byte[1024];
string message;
byte[] messagebytes;
int count = 0;
tcplistener tcplistener = new tcplistener(new ipendpoint(ipaddress.any, 13000));
tcplistener.start();
console.writeline("waiting for a connection... ");
tcpclient tcpclient = tcplistener.accepttcpclient();
console.writeline("connected.");
networkstream stream = tcpclient.getstream();
task.factory.startnew(() =>
{
while ((count = stream.read(buffer, 0, buffer.length)) != 0)
{
console.writeline($"{datetime.now:yyyy-mm-dd hh:mm:ss fff} reply from server {tcpclient.client.localendpoint.tostring()}:{encoding.utf8.getstring(buffer, 0, count)}");
}
});
task t = task.factory.startnew(() =>
{
while(!cancel)
{
message = console.readline();
if (message.toupper() == "y")
{
cancel = true;
return;
}
messagebytes = encoding.utf8.getbytes(message);
stream.write(messagebytes, 0, messagebytes.length);
}
});
if (cancel) tcpclient.close();
while (true)
{
if (t != null && t.iscompleted) break;
}
}
}
}
二、编写客户端代码，如下：
using system;
using system.linq;
using system.text;
using system.net;
using system.net.sockets;
using system.threading;
using system.threading.tasks;
namespace chatclient
{
class program
{
static void main(string[] args)
{
bool cancel = false;
byte[] buffer = new byte[1024];
string message;
byte[] messagebytes;
int count = 0;
try
{
tcpclient tcpclient = new tcpclient(new ipendpoint(dns.gethostentry(dns.gethostname()).addresslist.where(p => p.addressfamily == addressfamily.internetwork).first(), 14000));
tcpclient.connect(new ipendpoint(ipaddress.parse("192.168.94.26"), 13000));
networkstream stream = tcpclient.getstream();
task.factory.startnew(() =>
{
while ((count = stream.read(buffer, 0, buffer.length)) != 0)
{
console.writeline($"{datetime.now:yyyy-mm-dd hh:mm:ss fff} reply from client {tcpclient.client.localendpoint.tostring()}:{encoding.utf8.getstring(buffer, 0, count)}");
}
});
task t = task.factory.startnew(() =>
{
while (!cancel)
{
message = console.readline();
if (message.toupper() == "y")
{
cancel = true;
return;
}
messagebytes = encoding.utf8.getbytes(message);
stream.write(messagebytes, 0, messagebytes.length);
thread.sleep(10);
}
});
if (cancel) tcpclient.close();
while (true)
{
if (t != null && t.iscompleted) break;
}
}
catch(exception ex)
{
console.writeline(ex.message);
console.readkey();
}
}
}
}
三、先运行服务端代码，后再另外一台电脑运行客户端代码，效果图如下：
