Handling IDisposable object without the using statement

Question

I'm sure this is an easy question, but what am I supposed to do when handling an IDisposable object without the using statement?

Answer 1

All the using construct does is call on Dispose() which IDisposable mandates you implement.

So you can just call it yourself, instead of:

using (IDisposable something = new SomeDisposableClass()) {
    ...
}

Do:

IDisposable something = new SomeDisposableClass();

try {
   ...
} finally {    
   something?.Dispose();
}

Notice the use of the try..finally which will ensure Dispose() is called even if there is an exception.
