Re: Creating a class that is "readonly" for some classes?

You have to do it yourself. Make a check on each entrance into the object
properties.

There might be lots of ways of doing this. One way might be to make the
properties "internal" and place them in their own assembly. All classes
that need to write would be located in this assembly. Other ways might be
to wrap create another object that wraps the main object that can write to
the object, maybe using inheritance. Ultimately, you class may need at
least a reference to its parent/owner so that it can make a comparison.

Also, classes are always passed by references.
