What was the date 180 days ago?

Question

我怎样才能在180天前使用C＃获取日期？

Answer 1

DateTime oneEightyAgo = DateTime.Today.AddDays(-180);

Answer 2

EDIT:

DateTime day180 = Date.Now.AddDays(-180);

It's important to put it into a separate variable otherwise the value will be lost.

Answer 3

DateTime oneEightyAgo = DateTime.Now.ToUniversalTime().AddDays(-180); 

最好记录UTC ...

Answer 4

DateTime.Now.AddDays（-180）

Answer 5

DateTime.Now.AddDays(-180)
