Something tells me that Hijri calendar, or "Islamic calendar" might be not supported by .NET in its standard way, through ToString(IFormatProvider) or System.DateTime.ToString(String, IFormatProvider), if you used the implementation of the interface System.IFormatProvider as it is implemented by the type System.Globalization.CultureInfo, as it is usually done.

Please see:
http://msdn.microsoft.com/en-us/library/ht77y576.aspx[^],
http://msdn.microsoft.com/en-us/library/8tfzyc64.aspx[^],
http://msdn.microsoft.com/en-us/library/system.iformatprovider.aspx[^].

I think, at least one background reason of such state of affairs is that the format providers based on particular cultures, are based on cultural preferences related to certain nations, or group of nations sharing some cultural elements such as language, but Islamic cultural traditions are pretty much international and only partially integrate in national cultures. You can take a chance of trying particular cultures of some Muslim countries, but I don't think that Hijri dominates even there to the extent that it can be included in the standard. You could just try though:
http://en.wikipedia.org/wiki/Hijri[^],
http://en.wikipedia.org/wiki/List_of_Muslim-majority_countries[^].

The code sample for such approach is shown in a MSDN article I referenced above, very first link; you can quickly try all country-based Islamic cultures, but I don't think you will find the case formatting as Hijri. So, even though I'm to best of my knowledge, you won't success in using just .NET Base Class Library (BCL), so you will need to apply fully custom approach.

First of all, you can develop a Hijri-specific of the System.IFormatProvider by yourself. In a more ad-hoc approach, you can simply develop your own variant of System.DateTime.ToString which could be as simple as having something like string TimeToHijriString(System.DateTime time /* , some options? */). All you would need is the description of the calendar I referenced above, plus using individual fields of System.DateTime.ToString for year, month, etc.:
http://msdn.microsoft.com/en-us/library/system.datetime.aspx[^].

As the Hijri also has 12 months per year, 7 days a week, I hope you can map it to the Gregorian calendar (known to all computer systems, http://en.wikipedia.org/wiki/Gregorian_calendar[^]) pretty well, without big problems.

Wish you the best of luck,

Hi,

Use this Method to convert from Hijri to Gregorian

C#

public static string ConvertDateCalendar(DateTime DateConv, string Calendar, string DateLangCulture)
      {
          DateTimeFormatInfo DTFormat;
          DateLangCulture = DateLangCulture.ToLower();
          /// We can't have the hijri date writen in English. We will get a runtime error

          if (Calendar == "Hijri" && DateLangCulture.StartsWith("en-"))
          {
              DateLangCulture = "ar-sa";
          }

          /// Set the date time format to the given culture
          DTFormat = new System.Globalization.CultureInfo(DateLangCulture, false).DateTimeFormat;

          /// Set the calendar property of the date time format to the given calendar
          switch (Calendar)
          {
              case "Hijri":
                  DTFormat.Calendar = new System.Globalization.HijriCalendar();
                  break;

              case "Gregorian":
                  DTFormat.Calendar = new System.Globalization.GregorianCalendar();
                  break;

              default:
                  return "";
          }

          /// We format the date structure to whatever we want
          DTFormat.ShortDatePattern = "dd/MM/yyyy";
          return (DateConv.Date.ToString("f", DTFormat));
      }

How to use

C#

string date = ConvertDateCalendar(DateTime.Now, "Hijri", "en-US")

Hope this may help you
