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：
