Learn About DateTime Struct In C#

Introduction

In C#, we can use the DateTime struct to perform date and time-related operations. DateTime can be instantiated by different methods.

Note. I have documented this article on 13-05-2018 (May 13, 2018). Hence, this date value will be used throughout.

To get today’s date, use DateTime.Now.

DateTime date = DateTime.Now;

You can pass Year, Month, and Date as parameters, which creates an assigned date with time as 12 AM.

date = new DateTime(1990, 01, 23);

To create a date with a specified time, pass Hour, Minute, and Seconds in addition to the above parameters. Time will be in a 24-hour format.

date = new DateTime(1990, 01, 23, 23, 10, 10);

To assign a maximum date and time range.

date = DateTime.MaxValue;

Display DateTime Object

You can display the DateTime object as simply as.

DateTime date = DateTime.Now;
Console.WriteLine("Date = " + karthi);

It is recommended to always use the ToString() method to display the Date.

Console.WriteLine("Date = " + date.ToString());

To Display Year, Month, Date, Hour, Minute, Second

Console.WriteLine("Year = " + date.Year);
Console.WriteLine("Month = " + date.Month);
Console.WriteLine("Date = " + date.Date);
Console.WriteLine("Day = " + date.Day);
Console.WriteLine("Day of Week = " + date.DayOfWeek);
Console.WriteLine("Day of Year = " + date.DayOfYear);
Console.WriteLine("Time of Day = " + date.TimeOfDay);
Console.WriteLine("Hour = " + date.Hour);
Console.WriteLine("Minute = " + date.Minute);
Console.WriteLine("Second = " + date.Second);
Console.WriteLine("Millisecond = " + date.Millisecond);

Note. To display today's date only without month and year, use “Day” as the date and it will return the assigned date value and reset time to 12 AM.

To Display Short Version of Date. Ex: 13-05-2018

Console.WriteLine("Short Date = " + date.ToShortDateString());

To Display Long Version of Date. Ex: 13 May 2018

Console.WriteLine("Long Date = " + date.ToLongDateString());

To Display Short Version of Time. Ex: 13:00

Console.WriteLine("Short Time = " + date.ToShortTimeString());

To Display Long Version of Time. Ex: 13:00:00

Console.WriteLine("Long Time = " + date.ToLongTimeString());
