			MessageBoxResult result = MessageBox.Show("안녕하세요?", "제목표시줄", MessageBoxButton.YesNo ,  MessageBoxImage.Warning);
			if (result == MessageBoxResult.Yes)
			{
				MessageBox.Show("Yes를 눌렀습니다.");
			}else if(result == MessageBoxResult.No)

				MessageBox.Show("No를 눌렀습니다.");

}

느낀점

MessageBox의 결과를 MessageBoxResult의 변수로 결과값을 받고 그에 따른 처리를 할 수가 있다.
