C# Question

If two class inherit an static field, will the objects of those classes share the same value?

Is it possible that different objects of different classes can use one shared item among themselves (e.g for providing some information on the fly) or better a means of communication between different objects of two different classes ?

Class Base
{
public static string SomeThing = "Shared With All";
}
Class Der1 :Base
{
public void DoSomeThing()
{
SomeThing = "SomeThing Goes in here...";
}
}

Class Der2 :Base
{
public void DoSomeThingElse()
{
Console.WriteLine"(SomeThing);
}
}

....
{
Der1 dr1 = new Der1();
dr1.DoSomeThing();
Der2 dr2 = new Der2();
dr2.DoSomeThingElse(); //shows 'SomeThing Goes in here...'
}


If it helps more, I am trying to create a designer of some kind and so I need to get track of all controls and their associations on the designer. Actually there are only two objects at the moment (one called transaction and the other is called place, different places can be associated with different transactions, and this association is done by the user clicking on one place and pointing to the other transactions (have you seen
Proteus
? something like that).

So this approach will help me know which object is referring which other object and thus and association between the two can be easily spotted and saved.

The static field isn't really inherited in the same way as normal fields are. There's still just one static field, Base.SomeThing. Both of your derived classes are referring to the same field: if anything changes Base.SomeThing, everything that accesses that field will see the change.
