如何在C＃中查找上个月的数字 [英] How to find last month number in C#

问题描述

你好



i想要在c＃中重温上个月的数字我试过但我只会在当月获得。



我尝试过：



string MonthNumber = DateTime.Now.Month.ToString（）;

i已经使用了上面的代码，它会给我当前的月号，我想要上个月的数字

也试过这个DateTime月= DateTime.Now.AddMonths（-1）;

但它会给我一个日期我只想要月份数

hello

i want to just retrive the last month number in c# i have try but i will get only current month.

What I have tried:

string MonthNumber = DateTime.Now.Month.ToString();
i have used above code it will give me current month number i want last months number
also tried this DateTime month = DateTime.Now.AddMonths(-1);
but it will give me hole date i just want the month number

推荐答案

尝试：

int lastMonth = DateTime.Now.AddMonths(-1).Month;

您需要获取Month属性as AddMonths（-1）将返回一个新的 DateTime 实例，如下所示：

You need to get the Month Property as AddMonths(-1) will return a new DateTime instance, do it like:

DateTime LastMonth = DateTime.Now.AddMonths(-1);
Console.WriteLine(LastMonth.Month);

试试 -

Try-

string MonthNumber = DateTime.Now.AddMonths(-1).Month.ToString(); 

希望，它有帮助：）
