如何自定义的CultureInfo的默认日历？(How to customize CultureIn

我想自定义日历波斯但设置的CultureInfo，因为这之后：

CultureInfo fa = new CultureInfo("fa-IR",true);
Thread.CurrentThread.CurrentCulture = fa;

月和天名称不更改，因此决定来覆盖默认日历。

我怎样才能做到这一点？

Answer 1:

您可以创建一个子类CultureInfo 。它的属性不会是只读的并且可以分配给它..

Answer 2:

覆盖对于我这样的初学者：

public class PersianCulture : CultureInfo
{

    private readonly System.Globalization.Calendar cal;

    private readonly System.Globalization.Calendar[] optionals;

    public PersianCulture()

        : this("fa-IR", true)
    {

    }
    public PersianCulture(string cultureName, bool useUserOverride)

        : base(cultureName, useUserOverride)
    {
        cal = base.OptionalCalendars[0];
        var optionalCalendars = new List<System.Globalization.Calendar>();
        optionalCalendars.AddRange(base.OptionalCalendars);
        optionalCalendars.Insert(0, new PersianCalendar());
        Type formatType = typeof(DateTimeFormatInfo);
        Type calendarType = typeof(System.Globalization.Calendar);
        PropertyInfo idProperty = calendarType.GetProperty("ID", BindingFlags.Instance | BindingFlags.NonPublic);
        FieldInfo optionalCalendarfield = formatType.GetField("optionalCalendars",BindingFlags.Instance | BindingFlags.NonPublic);
        var newOptionalCalendarIDs = new Int32[optionalCalendars.Count];

        for (int i = 0; i < newOptionalCalendarIDs.Length; i++)

            newOptionalCalendarIDs[i] = (Int32)idProperty.GetValue(optionalCalendars[i], null);
        optionalCalendarfield.SetValue(DateTimeFormat, newOptionalCalendarIDs);

        optionals = optionalCalendars.ToArray();

        cal = optionals[0];

        DateTimeFormat.Calendar = optionals[0];
        DateTimeFormat.MonthNames = new[] { "فروردین", "اردیبهشت", "خرداد", "تیر", "مرداد", "شهریور", "مهر", "آبان", "آذر", "دی", "بهمن", "اسفند", "" };

        DateTimeFormat.MonthGenitiveNames = new[] { "فروردین", "اردیبهشت", "خرداد", "تیر", "مرداد", "شهریور", "مهر", "آبان", "آذر", "دی", "بهمن", "اسفند", "" };

        DateTimeFormat.AbbreviatedMonthNames = new[] { "فروردین", "اردیبهشت", "خرداد", "تیر", "مرداد", "شهریور", "مهر", "آبان", "آذر", "دی", "بهمن", "اسفند", "" };

        DateTimeFormat.AbbreviatedMonthGenitiveNames = new[] { "فروردین", "اردیبهشت", "خرداد", "تیر", "مرداد", "شهریور", "مهر", "آبان", "آذر", "دی", "بهمن", "اسفند", "" };

        DateTimeFormat.AbbreviatedDayNames = new string[] { "ی", "د", "س", "چ", "پ", "ج", "ش" };

        DateTimeFormat.ShortestDayNames = new string[] { "ی", "د", "س", "چ", "پ", "ج", "ش" };

        DateTimeFormat.DayNames = new string[] { "یکشنبه", "دوشنبه", "ﺳﻪشنبه", "چهارشنبه", "پنجشنبه", "جمعه", "شنبه" };
        DateTimeFormat.AMDesignator = "ق.ظ";
        DateTimeFormat.PMDesignator = "ب.ظ";

    }
    public override System.Globalization.Calendar Calendar
    {

        get { return cal; }

    }
    public override System.Globalization.Calendar[] OptionalCalendars
    {

        get { return optionals; }

    }
}

然后在Page_Load ：

PersianCulture fa = new PersianCulture();

Thread.CurrentThread.CurrentCulture = fa;

形成这里

Answer 3:

呈现在控制之前，您可以设置线程的CultureInfo，一旦控件呈现恢复。
