Learners question: Static methods

[Madhu]

Hi all,

I am new to c#. I was trying out the following:

class A
{
private static void doSomething()
{
System.Console.WriteLine("Class A is doing something");
}
}

class B
{
private static void Main()
{

A.doSomething();
}
}
If I compile the above code, I get the following error:

error CS0122: 'A.doSomething()' is inaccessible due to its
protection level

If I remove the private keyword from the method doSomething() in class A,
the file gets compiled without errors.
The error is clear to me. But what is not clear is why the compiler does not
give error for the method Main(). It is also a static method which I have
decleared private which should mean its not accessible to anybody.

Thanks in advance,
Madhu.

Sorry, I forgot to mention in my mail that the code gets compiled only if I
specify public keyword.

I found such explanation of fact that
private static int Main() works.

Sujala,

public, private, protected and others are access attributes that are
enforced primarily by the compiler (at runtime only when dynamic invocation
is involved). Beyond that, the runtime is free to accept or ignore the
access specifiers - and in the case of Main, it kindly ignores them.

Matters such as these (and this is but one example of many others) are
implementation specific details for the runtime, not for a particular
language.

I'm still learning all this stuff, but I'll give it a shot...

Declaring the Main method as private static should indicate that is
available to other members of the type containing Main. However, declaring
your type as private static would make the type and all of its members
completely inaccessible.
