PersianCalendar.AlgorithmType Property

Definition

Gets a value indicating whether the current calendar is solar-based, lunar-based, or lunisolar-based.

public override System.Globalization.CalendarAlgorithmType AlgorithmType { get; }

Property Value

Always returns SolarCalendar.

Examples

The following example uses reflection to instantiate each Calendar type found in the .NET Framework and displays the value of its AlgorithmType property.

using System;
using System.Collections;
using System.Globalization;
using System.Reflection;

public class Example
{
   public static void Main()
   {
      Assembly assem = Assembly.GetAssembly(typeof(Calendar));
      Type[] types = assem.GetExportedTypes();
      Type[] calendars = Array.FindAll(types, IsValidCalendar);
      Array.Sort(calendars, new CalendarComparer());

      Console.WriteLine("{0,-30} {1}\n", "Calendar", "Algorithm Type");
      foreach (var cal in calendars) {
         // Instantiate a calendar object.
         ConstructorInfo ctor = cal.GetConstructor( new Type[] {} );
         Calendar calObj = (Calendar) ctor.Invoke( new Type[] {} );

         Console.WriteLine("{0,-30} {1}",
                          cal.ToString().Replace("System.Globalization.", ""),
                          cal.InvokeMember("AlgorithmType",
                                           BindingFlags.Public | BindingFlags.Instance | BindingFlags.GetProperty,
                                           null, calObj, null));
      }
   }

   private static bool IsValidCalendar(Type t)
   {
        if (t.IsSubclassOf(typeof(Calendar)))
            if (t.IsAbstract)
                return false;
            else
                return true;
        else
            return false;
   }
}

public class CalendarComparer : IComparer
{
   public int Compare(object x, object y)
   {
      Type tX = (Type) x;
      Type tY = (Type) y;

      return tX.Name.CompareTo(tY.Name);
   }
}
// The example displays the following output:
//       Calendar                       Algorithm Type

Remarks

A date calculation for a particular calendar depends on whether the calendar is solar-based, lunar-based, or lunisolar-based.
