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

问题描述

我正在使用 DataTable.Select 在日期范围内过滤数据表，我的条件字符串是:

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'"

此过滤器不返回任何行(即使我可以在未过滤的数据表中看到匹配的行).但是我注意到如果我将标准更改为(注意日/月换位):

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'"

数据表按预期过滤.显然，这似乎是一个日期本地化问题，是否有一种简单的方法来格式化日期以避免此问题?

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?

推荐答案

像这样使用标准的 ISO 格式日期时间(对于 11 月 3 日):

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'"

事实上，如果您希望在 11 月 3 日创建所有记录，您应该这样做，因为您还希望在最后一分钟创建记录，例如23:59:30:

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'"
