First and last day in month

While coding a solution in .Net to parse billings I needed to find first and last days in month. The first day is easy – just set “01” for day. But for last day there is nice solution, hope it’ll help you

   DateTime today = DateTime.Today;
   DateTime endOfMonth = new DateTime(today.Year, today.Month, 1).AddMonths(1).AddDays(-1);
