Do I need to use the "using" keyword in every object that implements IDisposable?

Question

I am calling a third-party library where so many classes implement IDisposable.

Do I need to use a template for all of them?

Answer 1

It ensures that resources are cleaned correctly, whether or not exceptions occur.

IDisposable should only be implemented on classes that need to clean up resources, so ensuring that they do this is good practice.
