Use a static constructor. : Constructor : Class C# Examples

Use a static constructor.

    
using  System;  
  
class  Cons  {  
    public  static  int  a;  
    public  int  b;  
  
    //  static  constructor  
    static  Cons()  {  
        a  =  99;  
        Console.WriteLine("Inside  static  constructor.");  
    }  
  
    //  instance  constructor  
    public  Cons()  {  
        b  =  100;  
        Console.WriteLine("Inside  instance  constructor.");  
    }  
}  
    
class  MainClass  {  
    public  static  void  Main()  {      
        Cons  ob  =  new  Cons();  
  
        Console.WriteLine("Cons.a:  "  +  Cons.a);  
        Console.WriteLine("ob.b:  "  +  ob.b);  
    }  
}
    
   
  
   

Inside static constructor.
Inside instance constructor.
Cons.a: 99
ob.b: 100
