برنامه ماشین حساب سی شارپ( سورس رایگان)

برنامه ماشین حساب، از تمام قابلیت های اساسی ماشین حساب مانند افزودن، تفریق، ضرب، بخش، جذر و غیره را پشتیبانی می کند.

برای مبتدیان که در حال تلاش برای یادگیری C # هستند بسیار مفید است.

توضیحات
تمام رویداد کلیک روی دکمه عددی توسط یک رویداد انجام شده است. درون دستگیره، با استفاده از دکمه مربوط به ویژگی Properties نام فرستنده شناسایی شده است.

عبارت Switch – Case برای خواندن آسان کد استفاده شده است. من مطمئن هستم که این قطعه به همه مبتدیانی که می خواهند بدانند که چگونه برای توسعه برنامه های کاربردی فرم ویندوز کمک کنند کمک خواهد کرد.
