JapaneseCalendar.AlgorithmType Property

Definition

Namespace:

System.Globalization

Assembly:

System.Runtime.dll

Source:

JapaneseCalendar.cs

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

public:
 virtual property System::Globalization::CalendarAlgorithmType AlgorithmType { System::Globalization::CalendarAlgorithmType get(); };

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

member this.AlgorithmType : System.Globalization.CalendarAlgorithmType

Public Overrides ReadOnly Property AlgorithmType As CalendarAlgorithmType

Property Value

CalendarAlgorithmType

Always returns SolarCalendar.

Examples

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