Find specific date in the current week

Question

How would I be able to get the date of the Thursday in the current week? For example, Thursday of this current week is 7/8/2010

Answer 1

You can do this (alebit awkwardly) with the existing .NET DateTime. The trick is to use the DayOfWeek enum as an integer - since it denotes the days Sun - Sat in ascending numeric order (0-6).

DateTime someDay = DateTime.Today;
var daysTillThursday = (int)someDay.DayOfWeek - (int)DayOfWeek.Thursday;
var thursday = someDay.AddDays( daysTillThursday );

Or even more simply:

var today = DateTime.Today;
var thursday = today.AddDays(-(int)today.DayOfWeek).AddDays(4);
