Getting a short day name
提问by MaiOM
I was wondering on how to write a method that will return me a string which will contain the short day name, example:
我想知道如何编写一个方法来返回一个包含短日期名称的字符串，例如：
public static string GetShortDayName(DayOfWeek day)
now if i call:
现在如果我打电话：
string monday = GetShortDayName(DayOfWeek.Monday);
I will get back "mo" if culture is en, or "lu" if culture is at example it.
如果文化是 en，我会找回“mo”，如果文化是例子，我会找回“lu”。

You can use DateTimeFormatInfo.AbbreviatedDayNames. For example:
您可以使用DateTimeFormatInfo.AbbreviatedDayNames. 例如：
string[] names = culture.DateTimeFormat.AbbreviatedDayNames;
string monday = names[(int) DayOfWeek.Monday];

The closest you can get is use a custom date and time format string- specifically ddd.
最接近的是使用自定义日期和时间格式字符串- 特别是ddd。
This will return an abbreviation - you can substring the result to get to 2 characters.
这将返回一个缩写 - 您可以将结果子串化为 2 个字符。
You will need to use a DateTimewith a day corresponding to the day of week you wish.
您需要将 aDateTime与您希望的星期几对应。

try:
尝试：
CultureInfo english = new CultureInfo("en-US");
string sunday = (english.DateTimeFormat.DayNames[(int)DayOfWeek.Sunday]).Substring(0, 2);
Or:
或者：
dateTimeFormats = new CultureInfo("en-US").DateTimeFormat;
string sunday = (dateValue.ToString("dddd", dateTimeFormats)).Substring(0, 2);

您可以在自定义格式字符串中使用“ddd”来获取短日期名称。例如。
