Use implicit keywords for implicit conversion of custom types, implicit keywords

In C #, the implicit keyword can be used for implicit conversion of custom types. The following is an example.

First define a Point class to indicate a Point:

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

Then, define a static method in the Point class for implicit conversion from string to Point type:

    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;        }    }

The process of use is very simple, just like our implicit conversion:

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

Note: Try to avoid errors during implicit conversion or handle exceptions. Otherwise, use explicit to change to forced conversion.
