[System.Runtime.InteropServices.ComVisible(false)]
public override DateTime MinSupportedDateTime { get; }
member this.MinSupportedDateTime : DateTime
[<System.Runtime.InteropServices.ComVisible(false)>]
member this.MinSupportedDateTime : DateTime
Public Overrides ReadOnly Property MinSupportedDateTime As DateTime

Property Value

The earliest date and time supported by the HijriCalendar type, which is equivalent to the first moment of July 18, 622 C.E. in the Gregorian calendar.

Attributes

Examples

The following code example gets the minimum value and the maximum value of the calendar.

using namespace System;
using namespace System::Globalization;

int main()
{
   // Create an instance of the calendar.
   HijriCalendar^ myCal = gcnew HijriCalendar;
   Console::WriteLine( myCal );
   
   // Create an instance of the GregorianCalendar.
   GregorianCalendar^ myGre = gcnew GregorianCalendar;
   
   // Display the MinSupportedDateTime and its equivalent in the GregorianCalendar.
   DateTime myMin = myCal->MinSupportedDateTime;
   Console::Write( "MinSupportedDateTime: {0:D2}/{1:D2}/{2:D4}", myCal->GetMonth( myMin ), myCal->GetDayOfMonth( myMin ), myCal->GetYear( myMin ) );
   Console::WriteLine( " (in Gregorian, {0:D2}/{1:D2}/{2:D4})", myGre->GetMonth( myMin ), myGre->GetDayOfMonth( myMin ), myGre->GetYear( myMin ) );
   
   // Display the MaxSupportedDateTime and its equivalent in the GregorianCalendar.
   DateTime myMax = myCal->MaxSupportedDateTime;
   Console::Write( "MaxSupportedDateTime: {0:D2}/{1:D2}/{2:D4}", myCal->GetMonth( myMax ), myCal->GetDayOfMonth( myMax ), myCal->GetYear( myMax ) );
   Console::WriteLine( " (in Gregorian, {0:D2}/{1:D2}/{2:D4})", myGre->GetMonth( myMax ), myGre->GetDayOfMonth( myMax ), myGre->GetYear( myMax ) );
}

Remarks

Microsoft Visual Basic represents time of day as the specified time on the minimum date supported by the DateTime type, which is January 1, 0001 C.E. However, the HijriCalendar type does not support that minimum date. Consequently, if you call a method to format the time of day using the current calendar but you do 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.
