c# using statement

The C# 'using' statement provides a convenient syntax that ensures the correct use of IDisposable objects.

Example:

  using (BlackJackForm blackjackform = new BlackJackForm())
  {
    Hide();
    blackjackform.ShowDialog();
    Show();
  }

The above is the equivalent of the following more verbose code:

  BlackJackForm blackjackform = new BlackJackForm()
  try {
    Hide();
    blackjackform.ShowDialog();
    Show();
  }
  finally {
    blackjackform.Dispose();
  }

The using statement only works with items implementing the IDisposable interface.
