Dim c as MyClass & Dim c as New MyClass

Question

It's a simple concept, but one I've never been taught. Can someone please explain the differences between the following 2 statements please:

Dim c as MyClass

Dim c as New MyClass

Answer 1

Dim c as New MyClass is a shortcut and strictly equivalent to the following:

Dim c as MyClass = New MyClass

Both are different to Dim c as MyClass: the statement without New only declares the variable, it doesn’t assign a value. This means that the variable has a default value of Nothing.

New MyClass, on the other hand, assigns a newly-created instance of that class to the variable.
