提取2个日期和时间之间的总小时数 [英] Extract total Hours between 2 dates and times

问题描述

所以，我有4个文本框.
txt01是日期，格式为21.08.2014
txt02是日期，格式为24.08.2014
txt03是时间，格式为12:00
txt04是时间，格式为09:00

我只需要在21.08.2014 12:00和24.08.2014 09:00之间获得完整的工作时间

问题是，如何在vb.net中做到这一点?

So, i have 4 textboxes.
txt01 is date in format 21.08.2014
txt02 is date in format 24.08.2014
txt03 is time in format 12:00
txt04 is time in format 09:00

I need to get only full hours between 21.08.2014 12:00 and 24.08.2014 09:00

The question is, how to do that in vb.net?
