윈도우즈 서비스에서

System.Environment.CurrentDirectory 을 호출하면 "C:\Windows\System32"를 카리킨다.

그럴때 두가지 방법이 있다.

1. System.Windows.Forms 을 참조하고 System.Windows.Forms.Application.StartupPath을 호출

2. System.Reflection.Assembly.GetEntryAssembly().Location

참고 : http://peterkellyonline.blogspot.kr/2011/04/configuring-windows-service.html

결국 어플리 케이션을 디테일하게 컨트롤 할려면 .Net에서 WinApi를 호출해야 한다는 결론

위 Url참고 하여 GetStartMode메소드 추가
