Я пытаюсь создать калькулятор с C# и WPF.
Цель состоит в том, чтобы изучать и тестировать новые вещи.
Вот код:

Я открыт для любых советов и идей, которые вы могли бы дать абсолютному новичку.
Причина, по которой я публикация этого сообщения связана с тем, что я не знаю, как сделать так, чтобы переменная "res" появлялась в TextBox после каждой операции.
Я видел в Интернете, что многие люди говорили о TextBox.text, но я не знаю, как используйте его.
Возможно, мне придется использовать его в .xaml.cs, но как я могу определить TextBox? Как моя программа узнает, к какому TextBox я хочу применить текст?
Кроме того, мне кажется, что есть лучший подход - создать число с помощью кнопок, а не создавать 10 отдельных функций (от button_click0 до button_click9) и я хотел бы услышать несколько идей.
Спасибо!
