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; } } }} |

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：
以上这篇c#使用tcplistener及tcpclient开发一个简单的chat工具实例就是小编分享给大家的全部内容了，希望能给大家一个参考，也希望大家多多支持服务器之家。
