找到最后完成的每周星期结束日期 [英] find week ending date of last completed week

对于任何给定的日期，你会怎么觉得最后完成一周的周结束日期，如果你每周从周日运行至周六？

 日期时间StartOfWeek = DateTime.Today.AddDays（ - （INT）DateTime.Today.DayOfWeek）;
日期时间EndOfLastWeek = StartOfWeek.AddDays（-1）;
 

For any given date, how would you find the week ending date of the last completed week, if your week runs from Sunday to Saturday?
