c#中使用自动属性减少代码输入量

public class Product
    {
        private String name;
        public String Name
        {
            get
            {
                return name;
            }
            private set
            {
                name = value;
            }
        }

        private Decimal price;
        public Decimal Price
        {
            get
            {
                return price;
            }
            set
            {
                price = value;
            }
        }

        public Product(String name, Decimal price)
        {
            this.price = price;
            this.name = name;
        }
    }

public class Product
    {
        public String Name
        {
            get;
            private set;
        }

        public Decimal Price
        {
            get;
            set;
        }

        public Product(String name, Decimal price)
        {
            Name = name;
            Price = price;
        }

        public override string ToString()
        {
            return String.Format("{0}:{1}", this.Name, this.Price);
        }
    }
