总是只接受一个字符串，或者把对方发来的接成yige

前者原因是while（true）漏了，后者是因为没关闭clientSocket.Receive，可以clientSocket.close();

        while (true)
        {
            int length = clientSocket.Receive(result);
            //string receiveSting = null;
            abc = Encoding.UTF8.GetString(result, 0, length);
            Debug.Log(abc);
        }

前者改动后可以省略后者的改动。
