Calculate previous week's start and end date

I need to get the previous week start date in c# for eg. today is Jan 9th. previous week start date is Jan 1th.

I am using the following code

    DayOfWeek weekStart = DayOfWeek.Sunday;
    DateTime startingDate = DateTime.Today;

    while (startingDate.DayOfWeek != weekStart)
        startingDate = startingDate.AddDays(-1);

    DateTime previousWeekStart = startingDate.AddDays(-7);

Is this the best way in c#

Thanks

Answer 1

As previously stated the duplicate's response will probably do for you

mondayOfLastWeek = DateTime.Now.AddDays( -(int)DateTime.Now.DayOfWeek - 6 );
sundayOfLastWeek = DateTime.Now.AddDays(-(int)DateTime.Now.DayOfWeek)
