Which is the best implement?!?

Hi Experts,

we use Singletons in some classes of our application.

here an example...
-----------------------------------------------------------
class name: Features
-----------------------------------------------------------
private string _Something;
public string Something
{
Get { return(_Something); }
Set { _Something = value; }
}

private static Features instance = null;

public static Features GetInstance()
            {
                  if(instance == null)
                  {
                        instance = new ExportContoller();
                  }

                  return instance;
            }

private Features()
{
}

(...)
-----------------------------------------------------------

and i'm asking myself which call method do i have to use... i mean which is the best one!?!?!

Method 1:
Features keyID = Features.getInstance();
keyID.Something = "AGAH876876";

or

Method 2:
Features.getInstance().Something = "AGAH876876";

Does they have different Lifetime?!?

thks!

At first glance, the two calls appear identical to me, because Features.instance is static.

I believe both calls are identical and are compiled into same code.

The only iisue I can see from the above code is:

instance = new ExportContoller();

'instance' is of type 'Features'. Why's that?

ExportContoller is a copy and paste error while posting.
It should ha been
instance = new Features();
