DataTable.Select日期格式问题 [英] DataTable.Select date format problem

问题描述

我使用DataTable.Select过滤日期范围的数据，我的条件字符串是：

 CreatedOn> ; ='03/11/2009 00:00:00'AND CreatedOn< ='03/11/2009 23:59:00'
  

此过滤器不返回任何行（即使可以在未过滤的数据表中看到匹配的行）。但是，如果我将条件改为（注意日/月转置），请注意：

 CreatedOn> ='11 / 03/2009 00:00:00'AND CreatedOn< ='11/03/2009 23:59:00'
  

预期的数据过滤器。显然，这似乎是一个日期本地化问题，是否有一种简单的格式化日期来避免这个问题？

解决方案

使用标准的ISO格式datetime（11月3日）：

 CreatedOn> ='2009-11-03 00： 00:00'AND CreatedOn< ='2009-11-03 23:59:00'
  

其实如果你想要11月3日创建的所有记录，你应该这样做，因为你也希望在最后一刻创建的记录，例如23:59:30：

 CreatedOn> ='2009-11-03'AND CreatedOn<'2009-11 -04'
  

有一个快速参考 here

I'm filtering a datatable on a date range using DataTable.Select, my criteria string is:

"CreatedOn >='03/11/2009 00:00:00' AND CreatedOn <='03/11/2009 23:59:00'"

This filter returns no rows (even though I can see matching rows in the unfiltered datatable). However I notice if I change the criteria to (note the day/month transposition):

"CreatedOn >='11/03/2009 00:00:00' AND CreatedOn <='11/03/2009 23:59:00'"

The datatable filters as expected. Clearly this seems to be a date localisation issue, is there an easy way to format the date to avoid this issue?

解决方案

Use a standard ISO format datetime like this (for 3rd Nov):

"CreatedOn >='2009-11-03 00:00:00' AND CreatedOn <='2009-11-03 23:59:00'"

In fact, if you want all records created on 3rd Nov, you should really do this as you also want records created in that last minute e.g. 23:59:30:

"CreatedOn >='2009-11-03' AND CreatedOn < '2009-11-04'"
