About
In this code snippet, we will take a look at DateTime in C#.
DateTime is used to represent dates and times in code. The DateTime class contains many useful methods to manipulate the date(formatting the date, adding/subtracting years, months, days, hours, …).
Let’s have a look at the code below to see how to use DateTime.
Code:
using System;
namespace DateTimeExample
{
class Program
{
static void Main(string[] args)
{
//Get current time.
DateTime dateTime = DateTime.Now;
Console.WriteLine(dateTime.ToString());
//Set a time. (int year, int month, int day, int hour, int minute, int second)
dateTime = new DateTime(2023, 10, 6, 12, 24, 30);
Console.WriteLine(dateTime.ToString());
//Add/remove time.
dateTime.AddMonths(-1); //Removes 1 month.
dateTime.AddDays(1);
dateTime.AddHours(1);
//...
//Format the date.
Console.WriteLine("Year: " + dateTime.Year.ToString() + " Month: " + dateTime.Month.ToString());
//or (https://learn.microsoft.com/en-us/dotnet/standard/base-types/custom-date-and-time-format-strings)
Console.WriteLine(dateTime.ToString("yyyy-MM-dd HH:mm:ss")); //year, month, day hour, minutes, seconds
//Use a time span to get the time difference.
TimeSpan timeDiff = dateTime - DateTime.Now;
Console.WriteLine(timeDiff.ToString());
//Parse a string to DateTime.
dateTime = DateTime.Parse("2023-05-18 12:00:36");
Console.WriteLine(dateTime.ToString());
Console.ReadLine();
}
}
}
Resulting output:
