8.6.1.An example that uses an implicit conversion operator.
using System; 
 
class TwoDimension 
  int x, y;
 
  public TwoDimension() { 
     x = y = 0
  
  public TwoDimension(int i, int j) { 
     x = i; 
     y = j;
  
 
  // Overload binary +. 
  public static TwoDimension operator +(TwoDimension op1, TwoDimension op2
  
    TwoDimension result = new TwoDimension()
 
    result.x = op1.x + op2.x;  
    result.y = op1.y + op2.y;  
 
    return result; 
  
 
  // An implicit conversion from TwoDimension to int. 
  public static implicit operator int(TwoDimension op1
  
    return op1.x * op1.y; 
  
   
  // Show X, Y
  public void show() 
  
    Console.WriteLine(x + ", " + y)
  

 
class MainClass 
  public static void Main() { 
    TwoDimension a = new TwoDimension(12)
    TwoDimension b = new TwoDimension(1010)
    TwoDimension c = new TwoDimension()
    int i; 
 
    Console.Write("Here is a: ")
    a.show()
    Console.WriteLine()
    Console.Write("Here is b: ")
    b.show()
    Console.WriteLine()
 
    c = a + b; // add a and b together 
    Console.Write("Result of a + b: ")
    c.show()
    Console.WriteLine()
 
    i = a; // convert to int 
    Console.WriteLine("Result of i = a: " + i)
    Console.WriteLine()
 
    i = a * - b; // convert to int 
    Console.WriteLine("result of a * 2 - b: " + i)
  
}
Here is a: 1, 2

Here is b: 10, 10

Result of a + b: 11, 12

Result of i = a: 2

result of a * 2 - b: -96
