you might also make the follwing a bit easier to read:
> if (MessageBox.Show(question, caption,MessageBoxButtons.YesNo, MessageBoxIcon.Question)==DialogResult.Yes)

DialogResult user_choice = MessageBox.Show(question, caption,MessageBoxButtons.YesNo, MessageBoxIcon.Question);
if (user_choice ==  DialogResult.Yes)
{
  ..
}
else
{
 ...
}
