DateTime.Now.AddDays(-1) will get date-time for exactly 24hrs ago, but how do I get the time for yesterday at a specific hour?

Question

I want to somehow specify a time in my Datetime.Now so for instance I know that

DateTime.Now.AddDays(-1);

will get the date for yesterday exactly 24hrs ago but I want to get the date for yesterday at a specific time, for instance 5pm.

I can't find anything useful in relation to this on StackOverflow, any suggestions?

Solution 1

Use:

DateTime.Now.Date.AddDays(-1).AddHours(17);

Solution 2

You can create an instance of TimeSpan and delete/add in DateTime.Now.

OR

DateTime dt = DateTime.Now.AddDays(-1);

DateTime newdt = New DateTime(dt.Year, dt.Month, dt.Day, 17, 0, 0);
