Answer 1

有趣的问题:

解决方案是

void Main()
{
    DateTime zeroTime = new DateTime(1, 1, 1);
    DateTime olddate = new DateTime(1947, 8,15);
    olddate.Dump();
    DateTime curdate = DateTime.Now.ToLocalTime();
    curdate.Dump();

    TimeSpan span = curdate - olddate;

    // because we start at year 1 for the Gregorian 
    // calendar, we must subtract a year here.

    int years = (zeroTime + span).Year - 1;
    int months = (zeroTime + span).Month - 1;
    int days = (zeroTime + span).Day;

    years.Dump();
    months.Dump();
    days.Dump();
}
