Q 3)  When static constructor is invoked?

A static constructor is used to initialize any static data, or to  

perform a Particular action that needs performed once only. It is

called automatically before the first instance is created or any

static members are referenced.

Static constructors have the following properties: 
• A static constructor does not take access modifiers or have 
 parameters.
• A static constructor is called automatically to initialize the class 
 before the first instance is created or any static members are referenced.
• A static constructor cannot be called directly.
• The user has no control on when the static constructor is executed in the program.
• A typical use of static constructors is when the class is using a log file and the
  constructor is used to write entries to this file.
• Static constructors are also useful when creating wrapper classes for unmanaged
  code, when the constructor can call the LoadLibrary method.
 public class Bus {    
 // Static constructor:    
 static Bus()   
  {    
     System.Console.WriteLine("The static constructor invoked.");  
   } 
 public static void Drive()  
 {    
     System.Console.WriteLine("The Drive method invoked.");  
 }
  }  
class TestBus {     
static void Main()  
{  Bus.Drive();  

}

 }
