Is there a better deterministic disposal pattern than nested “using”s?

Question

In C#, if I want to deterministically clean up non-managed resources, I can use the \"using\" keyword. But for multiple dependent objects, this ends up nesting further and furt

Answer 1

The using statement is syntactic sugar that converts to:

   try
   {
      obj declaration
      ...
   }
   finally
   {
      obj.Dispose();
   }

You can explicitly call Dispose on your objects, but it won't be as safe, since if one of them throws an exception, the resources won't be freed properly.
