parameters describe an un representable datetime

🔥 문제발생

• parameters describe an un representable datetime
  • 초기 일자 설정 오류 (오늘날짜 ~ 한달 뒤)
    • 2025-10-31이면 2025-11-31이 없기에 에러.

 

⭐ 해결방법

• 무조건 월말로 설정.
  • 2025-11-31이면 2025-12-01로 설정.

DateTime today = DateTime.Today;
int nextMonth = today.Month == 12 ? 1 : today.Month + 1;
int nextYear = today.Year == 12 ? today.Year + 1 : today.Year;

DateTime startDate = sDate ?? today;
DateTime endDate = eDate ?? new DateTime(nextYear, nextMonth, DateTime.DaysInMonth(nextYear, nextMonth));
