private new void

[jjmraz]

Hi,

I have seen some code recently that had the following method
signatures:

private new void Push(object o)

And

public new objectname FunctionName()

So my question is what is happening here? With the first one why would
new be with a void return type? With the second one I am assuming that
the function would return a new object of that type, correct?

JJ,

In this case, the new is not related to the return type of the method.
Rather, new is used to indicate that the method shadows a method with the
same signature declared on the base class.

Hope this helps.

The new modifier makes it explicit that you want your method to not
override a virtual method with the same name and signature in a base
class, but rather hide it. See

Ah it says use me instead of the one in the base call when called upon?

Not quite. It says "this is actually a different method which happens
to have the same name, it's not trying to override another method".
