앞의 포스트에서 log4net의 동적 설정에 대해서 이런저런 이야기를 펼쳤다.
이 기준을 가지고 몇 가지 수정하면서 간단한 설정용 클래스를 만들었다.
물론 Rolling File에 대한 설정만 되는 간단한 구조이기 때문에 추후 지속적인 업데이트가 필요하다.
다만, 프로젝트들을 하면서 매번 코드 덩어리를 붙여넣기에 한계가 있어, 아예 클래스로 구성해봤다.

이 코드를 사용하려면, log를 사용하기 전에 실행되는 위치에 다음과 같은 코드를 넣어주어야 한다.
string sLogPath = "C:\Temp\this.log"; net.knoie.LoggerSettings.CreateInstance(sLogPath); net.knoie.LoggerSettings.Current.EnableRollingAppender = true; net.knoie.LoggerSettings.Current.Level = log4net.Core.Level.All;
sLogPath 라는 부분이 있는데, 이 안에 로그파일이 생성되어야 할 위치를 설정해 주면 된다.
이 클래스와 테스트 프로그램은 첨부파일로 같이 첨부한다.
