Keterangan
Properti Kind dari nilai yang dikembalikan DateTime selalu sama dengan DateTimeKind.Unspecified. Anda dapat mempertahankan Kind properti time
parameter dengan memanggil DateTime.SpecifyKind metode , seperti yang ditunjukkan contoh berikut.
returnTime = DateTime.SpecifyKind(cal.AddMonths(time, months), time.Kind);
returnTime = DateTime.SpecifyKind(cal.AddMonths(time, months), time.Kind)
