DateTimeOffset currentDate = DateTimeOffset.Now; DateTimeOffset tomorrow = currentDate.AddDays(1);
DateTimeOffset date = new DateTimeOffset(2022, 8, 1, 10, 0, 0, TimeSpan.Zero); DateTimeOffset updatedDate = date.Add(new TimeSpan(2, 30, 0));In example 1, we use the AddDays method to add a day to the current date and time. In example 2, we create a new DateTimeOffset object with the specified date and time, and add 2 hours and 30 minutes to it using the Add method. The DateTimeOffset struct is part of the System namespace in .NET, so the package library is likely the .NET Framework or .NET Core.
