I am a longtime programmer in many other languages (Delphi, C/C++, VB, 
VB.NET, etc), but am brand new to C#.  I am particularly puzzled by how to 
really use constants.

In most object oriented languages, there are obvious ways of creating true 
constants that have a lifetime that is the lifetime of the whole 
application, live outside of any object, are visible by code in other files, 
and usable within multiple objects.

In C#, by contrast, I am getting the impression that a constant may only be 
defined inside a classe, so that you have to create an object of that class 
first, then reference the constant as being a member of that class.  Is my 
impression wrong?

All I am trying to do is to make a separate file that contains some 
constants that live outside of any objects (so I don't have to create some 
object before I can use the constant), and which constants are visible from 
code in multiple objects.  In other words, like one would do with a C header 
file that only included constant
declarations.  I haven't been able to find any examples of how to do this in 
C#:  every code example that I have seen that even uses constants seems to 
create them inside a class.

Is it possible to create and use true constants in C#?  If so, could someone 
scratch out a crude 10-line outline of an example?  I'd really appreciate 
it!
