TaiwanCalendar.AlgorithmType Property

Updated: September 2010

Gets a value that indicates whether the current calendar is solar-based, lunar-based, or a combination of both.

Namespace:  System.Globalization
Assembly:  mscorlib (in mscorlib.dll)

public override CalendarAlgorithmType AlgorithmType { get; }

Property Value

Type: System.Globalization.CalendarAlgorithmType
Always returns the SolarCalendar value.

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.", ""),
                                           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;
                return true;
            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);
