DateOnly And TimeOnly In C#

DateOnly

• The new DateOnly struct can be used when we simply want to express the date component. a historical record, where the fact of the occurrence is more important to us than the precise minute it occurred

Syntax:

var date  = new DateOnly(Year, Month, Day);

Example:

var date = new DateOnly(2000, 3, 17);

Functions:

There are 4 functions:

1.  AddDays(int day)
2. AddMonths(int month)
3. AddYears(int year)

Example:

var date = new DateOnly(2019,05,21);
Console.WriteLine(date);

Output:

21/05/2019

1. AddDays()

Example:

var addDay = date.AddDays(1);
Console. WriteLine(addDay);

Output:

22/05/2019

2. AddMonths()

Example:

var addMonth = date.AddMonths(1);
Console. WriteLine(addMonth);

Output:

22/06/2019

3. AddYears()

var addYear = date.AddYears(1);
Console. WriteLine(addYear);

22/06/2020

TimeOnly

• When we are only interested in the time component, we can utilise the new TimeOnly struct.

TimeOnly(int hour, int minute)
TimeOnly(int hour, int minute, int second)
TimeOnly(int hour, int minute, int second, int millisecond)

Example:

var time = new TimeOnly(10,30);

var addHour = time.AddHours(2);
Console. WriteLine(addHour);
