您需要 Windows服务！

如果它直接与DateTime相关，请使用DateTime.Compare方法:

If its straight forward DateTime related stuff, use DateTime.Compare method:

DateTime date1 = new DateTime(2009, 8, 1, 0, 0, 0);
DateTime date2 = new DateTime(2009, 8, 1, 12, 0, 0);
int result = DateTime.Compare(date1, date2);
string relationship;

if (result < 0)
   relationship = "is earlier than";
else if (result == 0)
   relationship = "is the same time as";         
else
   relationship = "is later than";

Console.WriteLine("{0} {1} {2}", date1, relationship, date2);
// output: 
// 8/1/2009 12:00:00 AM is earlier than 8/1/2009 12:00:00 PM
