.NET 和 Windows 不同于标准的文化

Question

如果我运行下面的C#代码

var cultureInfo = new System.Globalization.CultureInfo("af");       
Console.WriteLine(cultureInfo.DateTimeFormat.ShortDatePattern);

我得到了 yyyy-MM-dd 的输出。

但是如果我在客户端使用 momentjs 并且运行下面的代码

var localeData = moment.localeData('af');
console.log(localeData._config.longDateFormat.L);

我得到 DD/MM/YYYY 的输出。

它们为什么不同？研究表明 momentjs 可能是正确的。如果我在客户端输入一个日期，然后尝试在服务器上解析它，就会出现问题。

Answer 1

var cultureInfo = new System.Globalization.CultureInfo("af");

等于

af-ZA   Afrikaans - South Africa    0x0436  AFK

Date and time notation in South Africa

South Africa signed up to use ISO 8601 for date and time representation through national standard ARP 010:1989 in 1998. The most recent South African Bureau of Standards standard SANS 8601:2009 "... is the identical implementation of ISO 8601:2004, and is adopted with the permission of the International Organization for Standardization" and was reviewed in 2016.

日期备注

Even so, the old date format is still commonly used in the format "dd/mm/yyyy", with the "day month year" order being more common with non-numeric month designations.

老实说 : momentjs 似乎是错误的
