Main Function

Praveen Srivastava

I wonder if there any way so that we can run main function without static keyword.

Why the main function is always kept static.

Which will be executed first the static constructor or the main function and why?

Hi Pravven
For the fist question. For C# and Java when an executable is designed then it support only one entry point from where the program is lunched. Now suppose that the Main which is the entry point is none static that means that is instance method that means more than one copy could be operational at the same time which leads to many entry points at the same time thing that is not supported by C# design.
The static main is a method within the class program and then the static constuctor of the class program is lunched before any class member as it will set logic or some set at the lunch time of the first instance of the class. You can see that by adding a static construtor and adding some code within it and then pressing F10 and stepping through the code

The only way that a non-static method can be executed is if there exists an instance of the class that the method is a member of. The only way that an instance can be created is if code executes to create it. So in order for a non-static method to be called, there must be a way for code to execute before there is any instance of any class.

Another way to look at it is that the Main function is called by Windows and Windows does not know where this an instance of a class for calling a non-static method.
