Question

有没有办法根据使用.NET框架的不同文化找到构成周末或工作周的日子？例如，一些穆斯林国家从周日到周四有一个工作周。

Answer 1

我唯一知道的是如何让这一周开始。也许这有助于：

CultureInfo.CurrentCulture.DateTimeFormat.FirstDayOfWeek

来自System.Globalization的

，也许你会在这个包里找到一些东西。

有几个日历类，如JulianCalendar, HebrewCalendar等。有可能找到你想要的东西。

Answer 2

没有人有解决方案，所以我写了一个。这使用国家来确定一天是工作日，周末还是1/2工作日（某些国家/地区的星期六）。这方面有些含糊不清，因为墨西哥星期六的半天是“习惯性的”，但不是正式的。对于这样的情况，我将其设置为工作时间。

这包括除马来西亚其他3个省份以外的所有省份，这些省份与马来西亚其他省份不同。 AFAIK，CultureInfo.Name对这3个省没有明显的价值。最有趣的国家，文莱周末是周五和周四星期天，星期六是工作日。

代码可以Is it the weekend下载为项目吗？主要代码如下：

using System.Globalization;

Answer 3

我不会给你一个.NET答案，但我会说你不会以“文化”为基础，而是以国家为基础。

您可以从知识产权中获得国家的准确度（但绝不会是100％）。在那之后，我会建议大量的谷歌搜索，因为我怀疑你会找到已经编写的代码。

（您也可以查看一些开源日历/约会程序，尤其是广泛使用的程序，如Linux，或者Lightning，Thunderbird插件。如果您浏览他们的代码，您可能会找到相关的数据此）

幸运的是，你只是面对一件事，而不是一件难以实施的事情。

祝你好运！

发现这个问题很有意思 - 我自己没有答案..但找到了一个有趣的资源 - 还讨论了日历。

Answer 5

以下代码将一直有效，直到过去2天被视为文化周末。

：）

/// <summary>
/// Returns true if the specified date is weekend in given culture
/// is in. 
/// </summary>
public static bool IsItWeekend(DateTime currentDay, CultureInfo cultureInfo)
{
    bool isItWeekend = false;

    DayOfWeek firstDay = cultureInfo.DateTimeFormat.FirstDayOfWeek;

    DayOfWeek currentDayInProvidedDatetime = currentDay.DayOfWeek;

    DayOfWeek lastDayOfWeek = firstDay + 4;

    if (currentDayInProvidedDatetime == lastDayOfWeek + 1 || currentDayInProvidedDatetime == lastDayOfWeek + 2)
        isItWeekend = true;

    return isItWeekend;         
}

根据文化寻找周末
