C# comparing private static and public static method

Question

In C#, what is the difference between methods that are markedpublic staticand methods marked asprivate static?

How are they allocated and accessed?

Answer 1

A private static method can only be accessed within the class that it's defined in. A public static method can be accessed outside of the class.

public class MyClass
{ 
    private static void MyPrivateMethod()
    {
        // do stuff
    }

    public static void MyPublicMethod()
    {
        // do stuff
    }
}

public class SomeOtherClass
{
    static void main(string[] args)
    {
         MyClass.MyPrivateMethod(); // invalid - this method is not visible

         MyClass.MyPublicMethod(); // valid - this method is public, thus visible
    }
}

As far as memory allocation goes, see here:

Where are methods stored in memory?

Answer 2

Private static methods can only be accessed by other methods in that class. Public static methods are pretty much global in access.
