C#重写ToString方法实例

直接上代码了。

Demo1：加上价格标签

class Program
    {
        public decimal price { get; set; }
        static void Main(string[] args)
        {
            Program p = new Program();
            p.price = 25;
            Console.WriteLine(p.ToString());
            Console.ReadKey();
        }

        public override string ToString()
        {
            return "$"+price.ToString();
        }
    }

 

Demo1：修改时间的输出格式

 public DateTime time { get; set; }
        static void Main(string[] args)
        {
            Program p = new Program();

            p.time = DateTime.Now;

            Console.WriteLine(p.ToString());

            Console.ReadKey();
        }

        public override string ToString()
        {
            return string.Format("{0}年{1}月{2}日",time.Year,time.Month,time.Day);
        }
