Учим C# зная basic

Цель данной темы: разместить в интернет программы
по каким возможно быстро выучить C# зная basic

Никому никогда ничего не рекомендую и всегда пишу только про себя

Программы созданы мной на основе моей главной программы
где запрограммирован мой алгоритм в нескольких вариантах
и теперь программирую на C# сразу без перевода из basic

? Почему C# & basic?
Потому что компилируемые и есть онлайн компиляторы
и компилятор C# включен в Windows 7 Framework

Программы проверены: работают и каждый может проверить
и лично я компилирую и стартую через простейший bat
