根据文化寻找周末

Question

有没有办法根据不同的文化使用.NET框架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

没有人能解决这个问题，所以我写了一个。这使用国家/地区来确定一天是工作日、周末还是 1/2 工作日（某些国家/地区为星期六）。这其中存在一些含糊之处，因为在墨西哥，周六的 1/2 天是“惯例”，但不是官方的。对于这样的情况，我将其设置为工作时间。

这涵盖了马来西亚除 3 个省份之外的所有地区，这三个省份与马来西亚其他地区不同。AFAIK，CultureInfo.Name 对于这 3 个省份没有明显的值。最有趣的国家是文莱，周末是周五和周日，周六是工作日。

代码可以作为项目下载，是周末吗？主要代码如下：

using System;
using System.Globalization;

namespace windward
{
    /// <summary>
    /// Extensions for the CultureInfo class.
    /// </summary>
    public static class CultureInfoExtensions
    {
        /// <summary>
        /// The weekday/weekend state for a given day.
        /// </summary>
        public enum WeekdayState
        {
            /// <summary>
            /// A work day.
            /// </summary>
            Workday,
            /// <summary>
            /// A weekend.
            /// </summary>
            Weekend,
            /// <summary>
            /// Morning is a workday, afternoon is the start of the weekend.
            /// </summary>
            WorkdayMorning
        }

        /// <summary>
        /// Returns the English version of the country name. Extracted from the CultureInfo.EnglishName.
        /// </summary>

            if (parts.Length < 2)
                return ci.EnglishName;
            parts = parts[1].Split(new[] {','}, StringSplitOptions.RemoveEmptyEntries);
            return parts[parts.Length - 1].Trim();
        }

Answer 2

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 IP 获取国家/地区，准确度较高（但永远不会 100%）。之后，我建议您进行大量谷歌搜索，因为我怀疑您是否会找到已经编写的代码。

（您还可以研究一些开源日历/约会程序，尤其是广泛使用的程序，例如 Linux 上的程序，或者可能是 Lightning、Thunderbird 插件。如果您深入研究他们的代码，您可能会找到这方面的数据）

但幸运的是，你面临的只是磨难，而不是难以实施的事情。

祝你好运！
