I don t understand inheritance with base classes

Question

My knowledge of inheritance is rather rudimentary.

I want to design a base class that implements IDisposable and then let other classes that implement IDisposable inherit from it so that they all have the same base type.

It would enable me to group all of my belongings into a single list, allowing me to rid of everything at once when cleaning up. The problem is that in C#, a class can only inherit once and can only use interfaces otherwise.

Now, how may Thread-like classes inherit from my base class without me having to rewrite the Thread class from scratch?

It may sound silly, but in a nutshell, I want to allow existing classes to inherit a base class of my choice without losing their functionality. (So that all classes in a project share a similar basis that can be summed up into a single object type, such as List)

Is it even possible to do so?

Answer 1

If you just want to keep a list of objects that can be disposed of, you'll need a List<IDisposable>. Any class that implements that interface, either directly or indirectly, can be stored there.

var disposables = new List<IDisposable>();
disposables.Add(new MyClass1());
disposables.Add(new SomeClass());
disposables.Add(new AnotherClass());

disposables.ForEach(d => d.Dispose());

I don't know if this is perfect either. Just a pointer.
