How to get datetime yesterday and tomorrow in C #

Question

I have a code:

int MonthNow = System.DateTime.Now.Month; int YearNow = System.DateTime.Now.Year; int DayNow = System.DateTime.Now.Day; 

How can I get day, month and year in C # yesterday and tomorrow?

Of course, I can just write:

 DayTommorow = DayNow +1; 

but it may happen that tomorrow is another month or year. Are there any built-in tools in C # to learn yesterday and today?

Answer 1

You can find this information directly in the API link .

 var today = DateTime.Now; var tomorrow = today.AddDays(1); var yesterday = today.AddDays(-1); 

Answer 2

 DateTime tomorrow = DateTime.Now.AddDays(1); DateTime yesterday = DateTime.Now.AddDays(-1); 

Answer 3

Today:

DateTime.Today

Tomorrow:

 DateTime.Now.AddDays(1) 

Yesterday:

 DateTime.Now.AddDays(-1) 

Answer 4

You want DateTime.Today.AddDays(1) .

Answer 5

Use DateTime.AddDays() ( MSDN Documentation DateTime.AddDays Method ).

 DateTime tomorrow = DateTime.Now.AddDays(1); DateTime yesterday = DateTime.Now.AddDays(-1); 

Answer 6

You should do it this way if you want to receive yesterday and tomorrow at 00:00:00:

 DateTime yesterday = DateTime.Today.AddDays(-1); DateTime tomorrow = DateTime.Today.AddDays(1); // Output example: 6. 02. 2016 00:00:00 

Just remember that if you do it like this:

 DateTime yesterday = DateTime.Now.AddDays(-1); DateTime tomorrow = DateTime.Now.AddDays(1); // Output example: 6. 02. 2016 18:09:23 

then you will get the current time minus one day, not yesterday at 00:00:00.

Answer 7

The trick is to use "DateTime" to manage dates; use integers and strings when you need a “final result” from a date.

For example (pseudo code):

• Get "DateTime Tomorrow = Now + 1"

• Determine the date, day of the week, day of the month - no matter what you want - the total date.
