c# : console application - static methods

Question

why in C#, console application, in \"program\" class , which is default, all methods have to be static along with

static void Main(string[] args)
         


        

Answer 1

The Main method is static because it's the code entry point to the assembly. There is no instance of any object at first, only the class template loaded in memory and its static members including the Main entry point static method. Main is predefined by the C# compiler to be the entry point.

A static method can only call other static methods (unless there is an instance handle of something composited for use). This is why the Main method calls other static methods and why you get a compile error if you try to call a non-static (instance) method.

However, if you create an instance of any class, even of the Program class itself, then you start creating objects in your application on the heap area of memory. You can then start calling their instance members.
