I want to customize calendar to persian but after setting CultureInfo as this:
CultureInfo fa = new CultureInfo("fa-IR",true);
Thread.CurrentThread.CurrentCulture = fa;
name of month and days don't changed so decided to override default calendar.
How can I do that?
overriding for beginners like me:
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; }
}
}
then in Page_Load:
PersianCulture fa = new PersianCulture();
Thread.CurrentThread.CurrentCulture = fa;
form here
You can create a subclass of CultureInfo. The property of it will not be read-only and you can assign to it..
You can set CultureInfo of thread before the control is rendered and restore once the control is rendered.
Output :
Below example show's how you can render two different calendar with different CultureInfo.
