[Cの＃] C＃の上でたとえば、ソケット
Dạo này đang học C# trên trường nên tiện thể viết mấy bài ghi nhớ 😉
プログラム 1: 作成を入力してください 1 サーバーと 1 クライアント. クライアントは、情報のgethostnameを送る, gethosttime, サーバにgethostdate, サーバが受信して、名前の、対応する値を返します, 1時間, 日.
私たちは、作成 2 個々のプロジェクトmyserverという名前とMyClientという. あなたはCtrlキー私を実行すると + F5 (デバッグモードを削除し、新しいプロジェクトは、多くが経営する). 私のコードでは、比較的ので、あなたが追跡しようと指摘しています.

ようこそ、, bạn có thể cho mình hỏi tài liệu học tiếng việt về lập trình mạng, hoặc nguồn học trên mạng ở đâu?
多くのおかげで!
Cái này mình chỉ google thôi, và toàn google tiếng anh hết bạn ah
anh cho em hỏi chỗ ipe của client là khi truyền IPAddress vào là IP của client hay server vậy?
Của server bạn nhé, đang cần kết nối đến server mà.
自問してみてください, ユーザーは、貿易へのbinance.comツールを記述するための例えば電子現金取引プラットフォーム, リアルタイムのデータを提供, APIにより、注文販売. ツールを書くためにC＃を使用することができます自問してみてください, ソフトかどうか、およびソフトやその他の補助ツールを使用する必要があります. 感謝!
これだけでは明確でああではありません.
