Доброго времени суток. Мне нужно сделать порт кода с явы на шарп, но я не силен в яве. Подскажите мне шарповые аналоги используемых в данном коде классов. | Код |

--------------------
Ученые долго не знали как назвать частоту.Потом так и назвали Hz. |
[Sockets] Java -> C#, Подскажите сходные классы.
