Hi

I am trying to get a date range in c#.
I can get the one range by date1 = DateTime.Now();

But if I wanted to go back say 5 days how do I go about calculating the date
for that.

I was looking for a DateTime function that would convert the date into an
integer and then convert it back but without luck.

Any suggestions would be appreciated

Thanks in advance

Bill

推荐答案

使用AddDays方法。


DateTime date1 = DateTime.Now;

DateTime date2 = date1.AddDays（-5）;

Use the AddDays method.

DateTime date1 = DateTime.Now;
DateTime date2 = date1.AddDays(-5);

date1.Subtract（new TimeSpan（5,0,0,0））;

你试过吗，


DateTime fiveDaysAgo = DateTime.Now（）。AddDays（-5）;


？

Have you tried,

DateTime fiveDaysAgo = DateTime.Now().AddDays(-5);

?
