C# 클래스의 프로퍼티 List 가져오기 및 해당 프로퍼티 값 설정, 가져오기 (Get Property LIsts, Get Method Lists)

닷넷에서 제공하는 Reflection을 이용하면 클래스 내부의 프로퍼리 목록, 또는 메소드 목록을 가져와서
값을 지정하거나 가져올 수 있다.

GetProperties()메소드에서 파라메터로 넘어가는 BindingFlags 값을 합쳐서 특정 조건을 가진 항목만 가져올 수 있다.
Static Class 클래스의 경우는 SetValue나 GetValue에서 첫번째 파라메터인 object가 null로 들어간다. (#58, #65 라인)
Instance된 클래스의 경우는 SetValue나 GetValue에서 첫번째 마라메터에는 인스턴스된 객체가 들어간다. (#113, #120 라인)
