Hello guys. I'm working for an IT computer as an intern. I need to create an admin page that helps show detail and export data. The end-user can choose "Last month" option to see all data for the last month, I'm using C# LinQ to query like this:
public async Task<List<NotifyUsers>> Gets(int top)
{
DateTime firstDayOfLastMonth = ......; // Need to define first day of last month here
DateTime lastDayOfLastMonth = .......; // Need to define last day of last month here
return await _db.NotifyUsers.Where(x => x.CreatedDate >= firstDayOfLastMonth && x.CreatedDate <= lastDayOfLastMonth)
.Take(top).ToListAsync();
}I don't know how to set value for firstDayOfLastMonth and lastDayOfLastMonth variables.
Anyone can help me?
Thank you in advance!

I usually use this way:
DateTime today = DateTime.Now; DateTime fistDayOfCurrentMonth = new DateTime(today.Year, today.Month, 1); DateTime firstDayOfLastMonth = fistDayOfCurrentMonth.AddMonths(-1); DateTime lastDayOfLastMonth = fistDayOfCurrentMonth.AddDays(-1);I hope it is useful for you.

Do you hear about FluentDateTime package in C#? It's very simple like this:
var lastMonth = 1.Months().Ago().Date; var firstDayOfMonth = lastMonth.FirstDayOfMonth(); var lastDayOfMonth = lastMonth.LastDayOfMonth();Happy code :D:D:D
