Also, it is good practice to always call Dispose on any instance of a type that implements IDisposable. 

If you are the one "responsible" for that object. For example:

  void foo(Stream s) {
    s.Write(...);
    // should usually *not* invoke s.Dispose();
  }

whereas the creator of the object should (usually) either: Dispose() it when done:

  void bar() {
    using ( MemoryStream s = new MemoryStream() ) {
      foo(s);
      ...;
    }
  }

or be sure it has given that responsibility to some other code:

  class Baz: IDispoable {
    Stream s;
    void Dispose() { if ( s != null ) s.Dispose(); }
  }
  void quux(Baz baz) {
    baz.s = new MemoryStream();
  }
