Sharing properties across classes

[Morten Snedker]

How do I share a property across classes?

For example I'll have three classes:

- Settings
- Class1
- Class2

Class1 will initiate the class Settings with a New Settings and will
followingly set the properties in the class Settings.

After Class1 has set the properties of Settings, Class2 will use these
already set properties, but without a New.

How do I access the property values set by Class1 - from Class2? I
should I consider another approach?

Re: Sharing properties across classes

Does it make sense to have multiple instances for the Settings class ?

If not, try :
http://msdn.microsoft.com/en-us/libr...95(VS.71).aspx ("Shared
Members") or

http://en.wikipedia.org/wiki/Singleton_pattern

In particular with solution #1 you don't even have to create an instance.
You'll just use Settings.MyShar edProperty...

Take a look at the singleton pattern. By making the Settings class a
singleton, the Class1 class would get the instance of the Settings class
(and thereby creating it as it's the first use of the class). Then the
Class2 class could get the instance of the Settings class, and this
would be the same instance as the Class1 class initiated.

Re: Sharing properties across classes

You could also just use a module ,,, :-|

or just pass the properties to the other classes as parameters in the
constructor

just 2 extra simple solutions for your "problem"
