摘要

之所以要進(jìn)行Socket套接字通信庫(kù)封裝，主要是直接使用套接字進(jìn)行網(wǎng)絡(luò)通信編程相對(duì)復(fù)雜，特別對(duì)于初學(xué)者而言。實(shí)際上微軟從.net 2.0開始已經(jīng)提供了TCP、UDP通信高級(jí)封裝類如下：

TcpListener
TcpClient
UdpClient

微軟從.net 4.0開始提供基于Task任務(wù)的異步通信接口。而直接使用socket封裝庫(kù)，很多socket本身的細(xì)節(jié)沒(méi)辦法自行控制，本文目就是提供一種socket的封裝供參考。文中展示部分封裝了TCP通信庫(kù),UDP封裝也可觸類旁通：

CusTcpListener
CusTcpClient

TCP服務(wù)端

TCP服務(wù)端封裝了服務(wù)端本地綁定、監(jiān)聽(tīng)、接受客戶端連接，并提供了網(wǎng)絡(luò)數(shù)據(jù)流的接口。完整代碼：

public class CusTcpListener
    {
        private IPEndPoint mServerSocketEndPoint;
        private Socket mServerSocket;
        private bool isActive;
 
        public Socket Server
        {
            get { return this.mServerSocket; }
        }
        protected bool Active
        {
            get { return this.isActive; }
        }
        public EndPoint LocalEndpoint
        {
            get
            {
                if (!this.isActive)
                {
                    return this.mServerSocketEndPoint;
                }
                return this.mServerSocket.LocalEndPoint;
            }
        }
        public NetworkStream DataStream
        {
            get
            {
                NetworkStream networkStream = null;
                if (this.Server.Connected)
                {
                    networkStream = new NetworkStream(this.Server, true);
                }
                return networkStream;
            }
        }
 
        public CusTcpListener(IPEndPoint localEP)
        {
            this.mServerSocketEndPoint = localEP;
            this.mServerSocket = new Socket(this.mServerSocketEndPoint.AddressFamily, SocketType.Stream, ProtocolType.Tcp);
        }
 
        public CusTcpListener(string localaddr, int port)
        {
            if (localaddr == null)
            {
                throw new ArgumentNullException("localaddr");
            }
            this.mServerSocketEndPoint = new IPEndPoint(IPAddress.Parse(localaddr), port);
            this.mServerSocket = new Socket(this.mServerSocketEndPoint.AddressFamily, SocketType.Stream, ProtocolType.Tcp);
        }
 
        public CusTcpListener(int port)
        {
            this.mServerSocketEndPoint = new IPEndPoint(IPAddress.Any, port);
            this.mServerSocket = new Socket(this.mServerSocketEndPoint.AddressFamily, SocketType.Stream, ProtocolType.Tcp);
        }
 
        public void Start()
        {
            this.Start(int.MaxValue);
        }
        /// <summary>

        /// </summary>
        /// <param name="backlog">同時(shí)等待連接的最大個(gè)數(shù)（半連接隊(duì)列個(gè)數(shù)限制）</param>
        public void Start(int backlog)
        {
            if (backlog > int.MaxValue || backlog < 0)
            {
                throw new ArgumentOutOfRangeException("backlog");
            }
            if (this.mServerSocket == null)
            {
                throw new NullReferenceException("套接字為空");
            }
            this.mServerSocket.Bind(this.mServerSocketEndPoint);
            this.mServerSocket.Listen(backlog);
            this.isActive = true;
        }
        public void Stop()
        {
            if (this.mServerSocket != null)

                this.mServerSocket = null;

            this.isActive = false;
            this.mServerSocket = new Socket(this.mServerSocketEndPoint.AddressFamily, SocketType.Stream, ProtocolType.Tcp);
        }
 
        public Socket AcceptSocket()
        {
            Socket socket = this.mServerSocket.Accept();
            return socket;
        }

            CusTcpClient tcpClient = new CusTcpClient(this.mServerSocket.Accept());
            return tcpClient;
        }
    }

TCP客戶端

TCP客戶端封裝了客戶端本地綁定、連接服務(wù)器，并提供了網(wǎng)絡(luò)數(shù)據(jù)流的接口。完整代碼：

public class CusTcpClient : IDisposable
    {
        public Socket Client { get; set; }
        protected bool Active { get; set; }
        public IPEndPoint ClientSocketEndPoint { get; set; }
        public bool IsConnected { get { return this.Client.Connected; } }
        public NetworkStream DataStream
        {
            get
            {
                NetworkStream networkStream = null;
                if (this.Client.Connected)
                {
                    networkStream = new NetworkStream(this.Client, true);
                }
                return networkStream;
            }
        }

            this.ClientSocketEndPoint = localEP;
        }

            this.Active = true;
            this.ClientSocketEndPoint = (IPEndPoint)this.Client.LocalEndPoint;
        }
 
        public void Connect(string address, int port)
        {
            if (address == null)
            {
                throw new ArgumentNullException("address");
            }

            {

                if (dataStream != null)
                {

通過(guò)本次封裝演示可實(shí)現(xiàn)基于Socket的通信庫(kù)封裝，目的就是使用Socket通信庫(kù)讓應(yīng)用開發(fā)人員在進(jìn)行網(wǎng)絡(luò)通訊編程時(shí)無(wú)需關(guān)心底層通訊機(jī)制，而只關(guān)心應(yīng)用層的開發(fā)，讓開發(fā)變得更簡(jiǎn)潔。當(dāng)然UDP封裝類似，可自行設(shè)計(jì)。當(dāng)然本文只是一種示例，實(shí)際使用可使用.net自帶封裝庫(kù)或自定義封裝。

補(bǔ)充：目前有很多優(yōu)秀的開源Socket框架，比如SuperSocket、FastSocket等。
