Question

I am looking for a C# solution that will allow me to iterate backwards over a date.
Starting at the current date or provided date I would like to loop over the date subtracting one day each time through the loop for a given number of days. It should of course be able to detect when the month has changed or it is a leap year etc., and return the date in MM-DD-YYYY format.

Answer 1

Should be easy enough:

var givenNumberOfDays = 30;
for( DateTime day = DateTime.Now; day > DateTime.Now.AddDays( -givenNumberOfDays); day = day.AddDays(-1) )
{
  //perform your logic here
  var dateInCorrectFormat = day.ToString("MM-dd-yyyy");
}
