Overload the int + object

<source lang="csharp">using System;

class TwoDimension {

 int x, y;

 public TwoDimension() { 
    x = y = 0; 
 } 
 public TwoDimension(int i, int j) { 
    x = i; 
    y = j;
 } 

 // Overload binary + for int + object. 
 public static TwoDimension operator +(int op1, TwoDimension op2) 
 { 
   TwoDimension result = new TwoDimension(); 

   result.x = op2.x + op1; 
   result.y = op2.y + op1; 

   return result; 
 } 

 // Show X, Y
 public void show() 
 { 
   Console.WriteLine(x + ", " + y); 
 } 

}

class TwoDimensionDemo {

 public static void Main() { 
   TwoDimension a = new TwoDimension(1, 2); 
   TwoDimension b = new TwoDimension(10, 10); 
   TwoDimension c = new TwoDimension(); 

   Console.Write("Here is a: "); 
   a.show(); 
   Console.WriteLine(); 
   Console.Write("Here is b: "); 
   b.show(); 
   Console.WriteLine(); 

   c = 15 + b; // int + object 
   Console.Write("Result of 15 + b: "); 
   c.show(); 
 } 

}</source>

Here is a: 1, 2
Here is b: 10, 10
Result of 15 + b: 25, 25
