format date in c#

Question

How can I format a date as dd/mm/yyyy or mm/dd/yy ?

Like in VB format("dd/mm/yy",now)

How can I do this in C#?

Answer 1

Better yet, use just

DateTime.Now.ToString() 

or

DateTime.Now.ToString(CultureInfo.CurrentCulture) 

to use the format the user prefers.

Answer 2

string.Format("{0:dd/MM/yyyy}", DateTime.Now)

Look up "format strings" on MSDN to see all formatting options.

Use yy, yyyy, M, MM, MMM, MMMM, d, dd, ffffd, ffffdd for the date component

Use h, hh, H, HH, m, mm, s, ss for the time-of-day component

Answer 3

Try this :

String.Format("{0:MM/dd/yyyy}", DateTime.Now); // 01/31/2009
String.Format("{0:dd/MM/yyyy}", DateTime.Now); // 31/01/2009
String.Format("{dd/MM/yyyy}", DateTime.Now); // 31/01/2009

Answer 4

I ran into the same issue. What I needed to do was add a reference at the top of the class and change the CultureInfo of the thread that is currently executing.

using System.Threading;

string cultureName = "fr-CA";
Thread.CurrentThread.CurrentCulture = new CultureInfo(cultureName);

DateTime theDate = new DateTime(2015, 11, 06);
theDate.ToString("g");
Console.WriteLine(theDate);

All you have to do is change the culture name, for example: "en-US" = United States "fr-FR" = French-speaking France "fr-CA" = French-speaking Canada etc...

Answer 5

I think this is simple as you can convert to and from any format without any confusion

 DateTime.ParseExact(txt.Text, "dd/MM/yyyy", CultureInfo.InvariantCulture).ToString("yyyy/MM/dd"));

Answer 6

It's almost the same, simply use the DateTime.ToString() method, e.g:

DateTime.Now.ToString("dd/MM/yy");

Or:

DateTime dt = GetDate(); // GetDate() returns some date
dt.ToString("dd/MM/yy");

In addition, you might want to consider using one of the predefined date/time formats, e.g:

DateTime.Now.ToString("g");
// returns "02/01/2009 9:07 PM" for en-US
// or "01.02.2009 21:07" for de-CH 

These ensure that the format will be correct, independent of the current locale settings.

Check the following MSDN pages for more information

• DateTime.ToString() method
• Standard Date and Time Format Strings
• Custom Date and Time Format Strings

Some additional, related information:

If you want to display a date in a specific locale / culture, then there is an overload of the ToString() method that takes an IFormatProvider:

DateTime dt = GetDate();
dt.ToString("g", new CultureInfo("en-US")); // returns "5/26/2009 10:39 PM"
dt.ToString("g", new CultureInfo("de-CH")); // returns "26.05.2009 22:39"

Or alternatively, you can set the CultureInfo of the current thread prior to formatting a date:

Thread.CurrentThread.CurrentCulture = new CultureInfo("en-US");
dt.ToString("g"); // returns "5/26/2009 10:39 PM"

Thread.CurrentThread.CurrentCulture = new CultureInfo("de-CH");
dt.ToString("g"); // returns "26.05.2009 22:39"
