TaiwanCalendar.MinSupportedDateTime Property

Microsoft Silverlight will reach end of support after October 2021. Learn more.

Gets the earliest date and time supported by the TaiwanCalendar class.

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

Syntax

'Declaration
<ComVisibleAttribute(False)> _
Public Overrides ReadOnly Property MinSupportedDateTime As DateTime
[ComVisibleAttribute(false)]
public override DateTime MinSupportedDateTime { get; }

Property Value

Type: System.DateTime
The earliest date and time supported by the TaiwanCalendar class, which is equivalent to the first moment of January 1, 1912 C.E. in the Gregorian calendar.

Remarks

Microsoft Visual Basic represents time of day as the specified time on the minimum date supported by DateTime, which is January 1, 0001 C.E. However, the TaiwanCalendar class does not support that minimum date. Consequently, if your application calls a method to format the time of day using the current calendar but does not specify a format specifier, formatting uses the ISO 8601 sortable ("s") date/time pattern format specifier instead of the default general ("G") date/time pattern format specifier. For more information, see Standard Date and Time Format Strings.

Examples

The following example gets the minimum value and the maximum value of the TaiwanCalendar class.

Imports System.Globalization

Public Class Example

      ' Create an instance of the GregorianCalendar.
      Dim myGre As New GregorianCalendar()

      ' Display the MinSupportedDateTime and its equivalent in the GregorianCalendar.
      Dim myMin As DateTime = myCal.MinSupportedDateTime
      outputBlock.Text += String.Format("MinSupportedDateTime: {0:D2}/{1:D2}/{2:D4}", myCal.GetMonth(myMin), myCal.GetDayOfMonth(myMin), myCal.GetYear(myMin))
      outputBlock.Text += String.Format(" (in Gregorian, {0:D2}/{1:D2}/{2:D4})", myGre.GetMonth(myMin), myGre.GetDayOfMonth(myMin), myGre.GetYear(myMin)) & vbCrLf

      ' Display the MaxSupportedDateTime and its equivalent in the GregorianCalendar.
