Summary
Отзыв тьютора в FEEDBACK-519: курс склеивает число со строкой, но правило неявного превращения нигде не называет. Урок «Выражения в определениях» первым показывает такую склейку, поэтому фраза встаёт сразу после примера.
Console.WriteLine("The price is " + rublesCount + " rubles"); // => The price is 3750 rubles+Переменная
rublesCountхранит число, но склеивается со строками. Когда один из операндов+строка, C# сам превращает второй операнд в строку, поэтому в выводе число стоит как текст.+
Любая переменная может быть частью любого выражения.
+Обратную задачу, превращение числа в строку, решает метод
ToString().+
+var text = 345.ToString();
+Console.WriteLine(text + "!"); // => 345!
