How to change DateTime format in C#

How to change DateTime format in C#

Changing the serialization format of a DateTime object and parsing a string to a DateTime object can be a challenging task when you are developing a multi-lingual large-scale application. For example, 3rd party libraries might use different culture settings. Your database connection might need a specific datetime format. Users or clients might prefer different datetime formats.

For these reasons, you should be careful about handling DateTime formatting issues, while you are developing a multi-lingual application in .Net environment (e.g. C# language). Displayed datetime formats, processed datetime formats, and stored datetime formats can be different.

There are several methods to manage DateTime format in C# programming language.

Changing DateTime format with String.Format

Here is the example code:

DateTime dt = DateTime.Now;
String.Format("{0:y yy yyy yyyy}", dt); // 20 20 2020 2020

Changing DateTime format using ToString() method

Another style of changing the format is:

dt.ToString("MMMM dd, yyyy"); // February 28, 2020

Change .Net DateTime to Microsoft SQL (MSSQL) Date/Time format

dt.ToString("yyyy-MM-dd HH:mm:ss"); // 2020-02-28 16:13:47

The list of available datetime format specifiers are given below:

Specifier

DateTimeFormatInfo property

Pattern value (for en-US culture)

t

ShortTimePattern

h:mm tt

d

ShortDatePattern

M/d/yyyy

T

LongTimePattern

h:mm:ss tt

D

LongDatePattern

dddd, MMMM dd, yyyy

f

(combination of D and t)

dddd, MMMM dd, yyyy h:mm tt

F

FullDateTimePattern

dddd, MMMM dd, yyyy h:mm:ss tt

g

(combination of d and t)

M/d/yyyy h:mm tt

G

(combination of d and T)

M/d/yyyy h:mm:ss tt

m, M

MonthDayPattern

MMMM dd

y, Y

YearMonthPattern

MMMM, yyyy

r, R

RFC1123Pattern

ddd, dd MMM yyyy HH':'mm':'ss 'GMT' (*)

s

SortableDateTi­mePattern

yyyy'-'MM'-'dd'T'HH':'mm':'ss (*)

u

UniversalSorta­bleDateTimePat­tern

yyyy'-'MM'-'dd HH':'mm':'ss'Z' (*)

 

 

(*) = culture independent

 

Editing Current Culture to manage DateTime format

To change the DateTime format in the application-wide, you need to edit the current culture of the application. Here is an example of this:

String culture = "af-ZA";
Thread.CurrentThread.CurrentCulture = CultureInfo.CreateSpecificCulture(culture);
Console.WriteLine(culture + " ---> " + DateTime.Now);

You may also change the DateTime format for the GUI thread:

Thread.CurrentThread.CurrentUICulture = ...

Available DateTime formats for the given culture strings are listed below:
