[英]How to get DayOfWeek in a local CultureInfo?
DateTime dt = new DateTime(DateTime.Now.Year, DateTime.Now.Month, 1);
string day = dt.DayOfWeek.ToString();
day = day.Substring(0, 1).ToUpper();
MessageBox.Show(day); // result is "F"
How could I get the result in a local language (CultureInfo), for example - France and where can I find a list of languages references for this purpose ? 我如何以本地语言(CultureInfo)获得结果,例如-法国,在哪里可以找到为此目的使用的语言参考列表?
Assuming you've already got the CultureInfo
, you can use: 假设您已经拥有
CultureInfo
,则可以使用:
string dayName = dateTime.ToString("dddd", culture);
You'd then need to take the first character of it yourself - there's no custom date/time format for just that. 然后,您需要自己输入第一个字符-并没有自定义日期/时间格式。 You could use
ddd
for the abbreviated day name, but that's typically three characters, not one. 您可以使用
ddd
作为缩写的日期名称,但这通常是三个字符,而不是一个字符。
As for a list of cultures - you can use CultureInfo.GetCultures
. 至于文化列表,您可以使用
CultureInfo.GetCultures
。 It will vary by platform, and could vary over time and even by version of .NET, too. 它会因平台而异,并且可能会随时间变化,甚至随.NET版本也会变化。
As an aside, this code isn't ideal: 顺便说一句,此代码并不理想:
DateTime dt = new DateTime(DateTime.Now.Year, DateTime.Now.Month, 1);
If you happen to call it just before midnight at the end of a year, you could get the "old" year but then January as the month. 如果你碰巧在今年年底午夜之前调用它,你可以得到“老字号”的一年,但随后1月担任了一个月。 You should evaluate
DateTime.Now
(or DateTime.Today
) once, and then use the same value twice: 您应该一次评估
DateTime.Now
(或DateTime.Today
),然后两次使用相同的值:
DateTime today = DateTime.Today;
DateTime startOfMonth = new DateTime(today.Year, today.Month, 1);
Straight from the MSDN: MSDN on DateTime with CultureInfo 直接来自MSDN: DateTime上的MSDN与CultureInfo
DateTime dt = DateTime.Now;
// Sets the CurrentCulture property to U.S. English.
Thread.CurrentThread.CurrentCulture = new CultureInfo("en-US");
// Displays dt, formatted using the ShortDatePattern
// and the CurrentThread.CurrentCulture.
Console.WriteLine(dt.ToString("d"));
Try dt.ToString("dddd")
and then manipulate that string if necessary. 尝试
dt.ToString("dddd")
,然后在必要时处理该字符串。 See Custom Date and Time Format Strings . 请参阅自定义日期和时间格式字符串 。
DateTime dateValue = new DateTime(2008, 6, 11);
Console.WriteLine(dateValue.ToString("ddd",
new CultureInfo("fr-FR")));
it is as simple as this: 就这么简单:
var culture = new CultureInfo("da-DK");
var datestring =datetime.ToString("dd MMMMM yyyy kl. hh:mm",culture)
