C method for getting the first and last day dates of the last month

This article example shows how C# gets the first and last day dates of the last month. Share to everybody for everybody reference.

The specific implementation code is as follows:

int year = DateTime.Now.Year;// The current year   

int mouth = DateTime.Now.Month;// The current month   

  

int beforeYear = 0;  

int beforeMouth = 0;  

if (mouth <= 1)// If the current month is 1 Months, so the years have to be subtracted 1  

{  

    beforeYear = year - 1;  

    beforeMouth =12;// Last month,   

}  

else  

{  

   beforeYear = year;  

   beforeMouth = mouth - 1;// Last month,   

}  

string beforeMouthOneDay = beforeYear + " years " + beforeMouth + " month " + 1 + " day ";// Last month, the first 1 day   

string beforeMouthLastDay = beforeYear + " years " + beforeMouth + " month " + DateTime.DaysInMonth(year, beforeMouth) + " day ";// Last month 1 day 

On the last day of the month, you can also write:

string beforeMouthLastDay = DateTime.Parse(DateTime.Now.ToString("yyyy-MM-01")).AddDays(-1).ToString("yyyy-MM-dd"); // Get the last month 1 Day date
