服務(wù)器端的整體思路：

1、初始化IP地址和端口號(hào)以及套接字等字段；

2、綁定IP啟動(dòng)服務(wù)器，開始監(jiān)聽(tīng)消息? socketServer.Listen(10)；

3、開啟一個(gè)后臺(tái)線程接受客戶端的連接 socketServer.Accept()，這里需要注意的是服務(wù)器端有兩個(gè)Socket，一個(gè)負(fù)責(zé)監(jiān)聽(tīng)，另一個(gè)負(fù)責(zé)傳輸消息，分工明確；

4、接受客戶端消息? socketMsg.Receive()；

5、向客戶端發(fā)送消息 Send(bySendArray)；

6、當(dāng)然還應(yīng)該包括信息顯示方法和系統(tǒng)的退出方法。

客戶端整體思路：

1、初始化IP地址和端口號(hào)以及一些顯示信息和套接字；

2、啟動(dòng)客戶端連接 _SockClient.Connect(endPoint)；

3、開啟后臺(tái)線程監(jiān)聽(tīng)客戶端發(fā)來(lái)的信息 _SockClient.Receive(byMsgArray)；

4、客戶端發(fā)送數(shù)據(jù)到服務(wù)器??_SockClient.Send(byteArray)；

5、當(dāng)然也應(yīng)該包括退出系統(tǒng)和顯示信息方法。
