I'm starting to learn how to use C# with Excel 2003 but I cannot find the
detailed documentation of some of the objects. For example I have seen many
code examples which include a Range object property named Value2 and a
Worksheet method get_Range() but I have been unable to find a formal
definition of the Range and Worksheet objects which includes these
properties.
Can someone please tell me where to look.

Code examples are OK as an introduction but definitions of all classes and
objects as in .Net are necessary, are they not?
