. NET datetime function to get the starting and closing time of last month _ Practical tips

This example describes the. NET's datetime function to get the starting and closing times of the previous month. Share to everyone for your reference. The specific analysis is as follows:

A recurring headache in a report is the need to automatically select the last one months of data as the current report output. Online query some. NET C # Examples, found that the implementation of the more complex, in fact, this problem can be very simple to pass. NET's datetime function, because.

Lastmonthbegin = DateTime.Now.AddMonths (-1). AddDays (1-datetime.now.day);

Last month up time:

Copy Code code as follows:

Lastmonthend = DateTime.Now.AddDays (-datetime.now.day)

Done!!

I hope this article will be described to you. NET program design helps.
