具體步驟(思路)
服務器端:
第一步:創建一個用於監聽連接的Socket對像;
第二步:用指定的端口號和服務器的ip建立一個EndPoint對像;
第三步:用socket對像的Bind()方法綁定EndPoint;
第四步:用socket對像的Listen()方法開始監聽;
第五步:接收到客戶端的連接,用socket對像的Accept()方法創建一個新的用於和客戶端進行通信的socket對像;
第六步:通信結束後一定記得關閉socket;
客戶端:
第一步:建立一個Socket對像;
第二步:用指定的端口號和服務器的ip建立一個EndPoint對像;
第三步:用socket對像的Connect()方法以上面建立的EndPoint對像做爲參數,向服務器發出連接請求;
第四步:如果連接成功,就用socket對像的Send()方法向服務器發送信息;
第五步:用socket對像的Receive()方法接受服務器發來的信息 ;
第六步:通信結束後一定記得關閉socket;
