[c#] why does DateTime.ToString("dd/MM/yyyy") give me dd-MM-yyyy?

I want my datetime to be converted to a string that is in format "dd/MM/yyyy"

Whenever I convert it using DateTime.ToString("dd/MM/yyyy"), I get dd-MM-yyyy instead.

Is there some sort of culture info that I have to set?

The answer is


Slash is a date delimiter, so that will use the current culture date delimiter.

If you want to hard-code it to always use slash, you can do something like this:

DateTime.ToString("dd'/'MM'/'yyyy")

Pass CultureInfo.InvariantCulture as the second parameter of DateTime, it will return the string as what you want, even a very special format:

DateTime.Now.ToString("dd|MM|yyyy", CultureInfo.InvariantCulture)

will return: 28|02|2014


Dumb question/answer perhaps, but have you tried dd/MM/yyyy? Note the capitalization.

mm is for minutes with a leading zero. So I doubt that's what you want.

If you use MVC, tables, it works like this:

<td>@(((DateTime)detalle.fec).ToString("dd'/'MM'/'yyyy"))</td>

Add CultureInfo.InvariantCulture as an argument:

using System.Globalization;

...

var dateTime = new DateTime(2016,8,16);
dateTime.ToString("dd/MM/yyyy", CultureInfo.InvariantCulture);

Will return:

"16/08/2016"
