C# 使用yield实现循环

public class Car
    {
        public string name { get; set; }
        public int price { get; set; }
    }

    public class CarCollection
    {
        private Car[] carArray = new Car[8];

        public IEnumerator GetEnumerator()
        {
            foreach(Car c in carArray){
                yield return c;
            }
        }
    }
