Question

Is it possible to cast a custom class to a value type?

Here\'s an example:

var x = new Foo();
var y = (int) x; //Does not compile 

Is i

Answer 1

You will have to overload the cast operator.

    public class Foo
    {
        public Foo( double d )
        {
            this.X = d;
        }

        public double X
        {
            get;
            private set;
        }


        public static implicit operator Foo( double d )
        {
            return new Foo (d);
        }

        public static explicit operator double( Foo f )
        {
            return f.X;
        }

    }
