推荐答案

让我们说今天的日期是：

Let's say the date is today:

var user = "05-08-2012";
var date = DateTime.ParseExact(user, "MM-dd-yyyy", System.Globalization.CultureInfo.InvariantCulture);
var lastdate = new DateTime(date.Year, 12, 31);
var diff = lastdate - date;

diff.TotalDays 中包含的天数（感谢@Tung）。 lastdate 还包含一年的最后日期。

diff.TotalDays contains the number of days (thanks @Tung). lastdate also contains the last date for the year.
