利用implicit关键字做自定义类型隐式转换

    public class Point    {        public double X { get; set; }        public double Y { get; set; }    }

    public class Point    {        public double X { get; set; }        public double Y { get; set; }        public static implicit Operator Point(string constValue)        {            var result = new Point();            try            {                var arPoint = constValue.Split(new[] {","}, StringSplitOptions.RemoveEmptyEntries);                result.X = Convert.ToDouble(arPoint[0]);                result.Y = Convert.ToDouble(arPoint[1]);            }            catch            {                result.X = 0;                result.Y = 0;            }            return result;        }    }

            Point p = "3,4.5";            Console.WriteLine("X:{0}, Y:{1}", p.X, p.Y);
