Question

Can I create a class with a default return value? Lets say if I create an object of this class I get always a specific value, without calling the properties or something else. Example:

int i = new MyIntClass(/*something*/); //will return an int

Actually I would like to use a default function for returning something. Maybe like this:

class MyCalculator()
{
  public double a { get; set; }
  public double b { get; set; }

  MyCalculator(double a, double b)
  {
    this.a = a;
    this.b = b;
  }

  public double DoMath()
  {
    return a*b;
  }
}

/* somewhere else */
double result = new MyCalculator(5.5, 8.7);

result should be the result of DoMath(). Is that possible? I know its maybe not the best example, but something like this would be nice. Any ideas?

Answer 1

You can do an implicit cast.

Example (add to class):

public static implicit operator double(MyCalculator c)
{
  return c.DoMath();
}
