網路中兩個主機用socket連線=.=

互動需要雙方相同的協議,伺服器的ip地址,伺服器程序需要port

客戶端咱們不管,給伺服器配置成接收所有ip與埠

所以

socket只需要指定協議,埠即可

沒有異常處理,沒有關閉,沒有人數限制,沒有面向物件

伺服器思路:

一個伺服器自身socket

1. 指定協議

1. 指定接收地址port
2. 繫結地址與port
3. 讓socket處於監聽狀態(引數別管,這只是個等待佇列長度,並不是寫了10就是隻接受10個客戶端請求(那麼怎麼寫呢,末尾給出程式碼)
4. 獲取客戶端socket,開啟一個執行緒來處理資料(不然只接收一行)
5. 想加雙工通訊就是在伺服器和客戶端各多開個執行緒,這裡少寫點程式碼,看起來舒服

            serverSocket.Bind(point);
            serverSocket.Listen(10);
            Console.WriteLine("伺服器啟動成功");
            AccessToClient();
        }

        public void AccessToClient()
        {
            Socket clientSocket = serverSocket.Accept();
            Console.WriteLine("連線客戶端成功");

        public void AcceptClientData(object obj)
        {
            Socket clientSocket = obj as Socket;
            Byte[] bytes = new Byte[1024];
            //這裡客戶端斷開會異常 加try catch
            try
            {
                int length = clientSocket.Receive(bytes);
                //這裡length==0 不走
                if (length > 0)
                {
                    String str = Encoding.UTF8.GetString(bytes, 0, length);
                    Console.WriteLine("o((>ω< ))o:" + str);
                    AcceptClientData(obj);
                }
            }
            catch
            {
                Console.WriteLine("客戶端斷開");
            }

}
 

客戶端思路:

1. 也就是伺服器的開頭,建立socket
2. 配置ip port
3. 這一步不要繫結,直接連線就行
4. 這裡連線伺服器寫了個傳送資料,可以自測
5. 要接收伺服器資訊,多開個執行緒就行相信你可以的=.=
