when do I need Thread? whats that?...با دروددر این بلاگ تجربه ای راجب اینکه آیا در برنامه ام نیازی به ترد دارم یا نه را به اشتراک گذاشته ام:در ادامه کد مربوط به الگوریتم رمز گذاری سزار را با زبان c# می نویسم. در این برنامه ابتدا متن را از فایلی خوانده و الگوریتم را بر روی آن با تعداد شیفت 3 می نویسم.
