Properties

Properties are a convenient, built-in way to access private fields in C#.

You access properties the same way you would access a public field. Listing A.21 illustrates the use of properties to conceal private fields of the Point class.

Listing A.21. Properties in the Point Class
class Point{
   private double x=0;
   private double y=0;

   public Point(){
      x = 0;
      y = 0;
   }

   public Point(double X, double Y){
      x = X;
      y = Y;
   }

   public double X {
      get {  return x; }

      set {  x = value; }
   }

   public double Y{
      get{  return y;  }
      set {  y = value; }
   }

   public void print(){
      Console.WriteLine("(" + X + ", " + Y + ")" );
   }
}
