c# 文化信息的日期格式问题

Question

I try to format a local date into a string, but based on the local format. By example, for the 5 May 2020, if I use French, I expected "5 Mai, 2020", but I got "5 May, 2020"...

The month name is still in English !

Here is my code to test this:

Do you have any idea?

Thx

You need to use the DateTime.ToString overload that gets CultureInfo parameter as a second argument.

https://docs.microsoft.com/en-us/dotnet/api/system.datetime.tostring?view=netcore-3.1

So your code would look like (copying from the image you attached):

string FormattedPostDate = localDate.ToString(CultureInfo.GetCultureInfo("fr-FR").DateTimeFormat.MonthDayPattern, new System.Globalization.CultureInfo("fr-FR")) + ", " + localDate.Year;
