Why an object of a class is created inside a main method?

Question

Why an object of a class is created inside a main method and it does not work if created inside a class without any method?

Because, Object creation happens when something is executed at that time, memory is allocated and your objects goes to RAM. BTW, you can always create object inside class constructor public class employee { public employee() { var emp= new employee(){id=1,Name= "Sachin" }; } public int id {get;set;} public string name {get;set;} } Class, in reality is nothing, just a skelton, it becomes something or takes memory when object is created and compiler creates the object when he finds the reference of any class, obviously we can't execute a class directly, so until a method is executed no object will be created.

That's is because a programm needs a single static entry point (the main method itself) and most of the functionality is usually implemented in classes, to use the functions provided by a class you need an instance (object of a class). Class has a boundry of access because it is just a container which holds properties and methods within it. While Instance / Object represent ownership of Class. You can create an object of class in another class but for futher use you need to create a method to define the scope and accessibility. As shown below. public class Operator { public string Id { get ; set ; } public string Sign { get ; set ; } } public class ResearchAssistant { Operator op = new Operator(); void AssignOperator() { op.Id = "1" ; op.Sign = "+" ; } }
