Is everything an object?

[Brett]

In VB .NET everything is supposed to be an object. Say I have a report
title hard coded in a method. When a method is called, is the returned
title an object or a string?

Thanks,
Brett

It's a string object.

It's a string object.

What exactly does that mean? What is the difference between a string and a
string object?

The string returned has no properties, methods and cannot be instantiated.
Why would it be considered an object?

The string returned by a method that returns a string actually has methods,
and 'String' inherits from 'Object', which is the common base class of all
types (notice that this does not apply to interfaces because interfaces
cannot be instantiated).

Dim s As String = Foo(...)
MsgBox(s.ToLower())

Did you not notice such methods as "Split", "EndsWith and "StartsWith"?

Everything in .NET is an object. Even basic types such as integers and
singles are derived from Object. This is why they have the .ToString method
for example.

Brett,

In addition to the others, you can use a "default" return type for every
object
