这个问题在这里已有答案：

我想要在两个日期之间经过确切的年，月和日 .

DateTime startDate = new DateTime(1974, 8, 15);

DateTime endDate = DateTime.Now.ToLocalTime();

我想找到使用C＃的上述两天之间经过的年数，月数和天数？

我的预期产出年份：68个月：10天：23

我推荐了一篇帖子，因为他们只解释了几天Calculate difference between two dates (number of days)?

但我需要三年，一年，一天和一天 . 请帮助我如何计算......

Explanation for Duplicate ：已经在Calculate Years, Months, weeks and Days中发布了相同逻辑的问题，该问题中提供的答案过于冗长且 in my question I asked only Year, Month and Date not Week . The Concept is same but the logic is different for calculating days comparing to that question ，我在这里以非常简单的方式得到了答案 . I satisfied in my answer .

    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();
}
