Cómo: Utilizar la sobrecarga de operadores para crear una clase de números complejos (Guía de programación de C#)
Este ejemplo muestra cómo utilizar la sobrecarga de operadores para crear una clase de números complejos Complex que define la suma compleja.El programa muestra las partes real e imaginaria de los números y el resultado de la suma mediante un método sustituto del método ToString.
Ejemplo
public struct Complex
{
public int real;
public int imaginary;
// Constructor.
public Complex(int real, int imaginary)
{
this.real = real;
this.imaginary = imaginary;
}
// Specify which operator to overload (+),
// the types that can be added (two Complex objects),
// and the return type (Complex).
public static Complex operator +(Complex c1, Complex c2)
{
return new Complex(c1.real + c2.real, c1.imaginary + c2.imaginary);
}
// Override the ToString() method to display a complex number
// in the traditional format:
public override string ToString()
{
return (System.String.Format("{0} + {1}i", real, imaginary));
}
}
class TestComplex
{
static void Main()
{
Complex num1 = new Complex(2, 3);
Complex num2 = new Complex(3, 4);
// Add two Complex objects by using the overloaded + operator.
Complex sum = num1 + num2;
// Print the numbers and the sum by using the overridden
// ToString method.
System.Console.WriteLine("First complex number: {0}", num1);
System.Console.WriteLine("Second complex number: {0}", num2);
System.Console.WriteLine("The sum of the two numbers: {0}", sum);
// Keep the console window open in debug mode.
System.Console.WriteLine("Press any key to exit.");
System.Console.ReadKey();
}
}
/* Output:
First complex number: 2 + 3i
Second complex number: 3 + 4i
The sum of the two numbers: 5 + 7i
