Loop for all objects of class without List/Array

Question

It's possible to obtain a collection of all objects of certain class?

Given some arbitrary class, for example:

public class MyClass {
   public int anyVal;
   /* ...etc ... */
}

Is it possible to obtain a collection of all objects of certain class so you can iterate through them, like perhaps:

MyClass obj = new MyClass();
obj.anyVal = 333;

MyClass[] allObjects = //???              // <== HERE

foreach (MyClass mObj in allObjects) {
    Console.WriteLine("obj = " + mObj.anyVal);
}

@fubo i think the question is about instances of a class, but not about encapsulated objects. — Diligent Key Presser, Mar 04 '16 at 12:12
Do you mean iterating over all the properties? It's really unclear what you're trying to do at the moment. — Jon Skeet, Mar 04 '16 at 12:12
@fubo User does not asks how to iterate over properties of an instance. — tchelidze, Mar 04 '16 at 12:12
Why would you want to do that?? Don't "fix" design flaws with reflection mess. — Tim Schmelter, Mar 04 '16 at 12:12
@XXXYYY what you mean by *all objects of class without List/Array* ? where are they stored ? — tchelidze, Mar 04 '16 at 12:13

No. You'd have to examine the Heap somehow and check the type for every object there. Not something you want to be doing.
