WebC# Recursion Recursion Recursion in plain English Recursion can be defined as: A method that calls itself until a specific condition is met. An excellent and simple example of recursion is a method that will get the factorial of a given number: public int Factorial(int number) { return number == 0 ? 1 : n * Factorial(number - 1); } WebC# содержит два выражения использующих yield: yield return и yield break. yield может применяться в методах, операторах и свойствах.
