c# - 如何获得直到秒的日期和时间？

Question

我有两次如下:

DateTime time1=Datetimepicker1.value;
DateTime time2=file1.creationtime;

time1 和 time2 都有日期和时间显示 12-31-2014 15:00:33
但是当我两次比较时，它给出了错误的结果:

int result=DateTime.Compare(time1,time2);

结果值为0。
怎么办？

Answer 1

结果正确。根据this MSDN page该函数根据以下逻辑工作，假设日期被命名为 t1 和 t2:

 __Value Type__      __Condition__ 

 Less than zero      t1 is earlier than t2. 
 Zero                t1 is the same as t2. 
 Greater than zero   t1 is later than t2.
