再次特别感谢张子阳老师的文章,读后深感益处。
废话不多说,先贴代码
这是服务器端代码
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Net;
using System.Net.Sockets;
using System.Threading;
using System.Data.SqlClient;
namespace SeverConsole {
class Program {
const int bufferSize = 8192;//接受的最大字节数
static void Main(string[] args) {
Console.WriteLine("Sever is runing");
IPAddress ip = new IPAddress( new byte[]{127,0,0,1});
TcpListener tcpListener = new TcpListener(ip, 8500);//监听对象
tcpListener.Start();
while (true) {
try{
TcpClient remoteClient = tcpListener.AcceptTcpClient();//接受客户端的连接请求,会在此处等待。 不会继虚向下执行
Console.WriteLine(@"有客户端连入,{0}<--{1}", remoteClient.Client.LocalEndPoint, remoteClient.Client.RemoteEndPoint);
NetworkStream streamFromClient = remoteClient.GetStream();//获取连接到客户端的流
byte[] buffer = new byte[bufferSize];
int bytesRead = streamFromClient.Read(buffer, 0, bufferSize);//从客户端和服务器获取的流都是二进制形式的
Console.WriteLine("read {0} bytes from client", bytesRead);
string msg = Encoding.Unicode.GetString(buffer, 0, bytesRead);
Console.WriteLine("Received: {0}", msg);
string magSend = msg.ToUpper();
buffer = Encoding.Unicode.GetBytes(magSend);
lock (streamFromClient) {//为了保证数据的完整性以及安全性 锁定数据流
streamFromClient.Write(buffer, 0, buffer.Length);
Console.WriteLine("send: {0}", msg.ToUpper());
}
}catch(Exception ex){
Console.WriteLine(ex.Message);
}
}
Console.WriteLine(@"please press 'Q' to exit");
//Console.ReadLine();
ConsoleKey key;
do {
key = Console.ReadKey().Key;
} while (key != ConsoleKey.Q);
}
}
}
这是客户端代码
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Net;
using System.Net.Sockets;
namespace clientConsole {
class Program {
const int bufferSize = 8192;
static void Main(string[] args) {
Console.WriteLine("Client is running!");
TcpClient client;
for (int i = 0; i < 4; i++) {
client = new TcpClient();
try {
client.Connect("127.0.0.1", 8500);
} catch (Exception ex) {
Console.WriteLine(ex.Message);
}
Console.WriteLine("connecting successful");
Console.WriteLine("{0}-->{1}", client.Client.LocalEndPoint, client.Client.RemoteEndPoint);
string msg = "let me to connect with you ";
NetworkStream clientToSever = client.GetStream();
byte[] buffer = Encoding.Unicode.GetBytes(msg);
clientToSever.Write(buffer, 0, buffer.Length);
int t = buffer.Length;
Console.WriteLine("Send: {0}", msg);
lock (clientToSever) {//
int bytesRead = clientToSever.Read(buffer, 0, t);
msg = Encoding.Unicode.GetString(buffer, 0, buffer.Length);
Console.WriteLine("Received: {0}", msg);
}
}
ConsoleKey key;
do {
key = Console.ReadKey().Key;
} while (key != ConsoleKey.Q);
}
}
}
