DateTimeFormatInfo.LongTimePattern Property

Gets or sets the format pattern for a long time value, which is associated with the "T" format pattern.

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

Public Property LongTimePattern As String
Dim instance As DateTimeFormatInfo 
Dim value As String 

value = instance.LongTimePattern

instance.LongTimePattern = value

Property Value

Type: System.String
The format pattern for a long time value, which is associated with the "T" format pattern.


The property is being set to Nothing.


The property is being set and the DateTimeFormatInfo is read-only.

See DateTimeFormatInfo for patterns that can be combined to construct custom patterns, for example, "HH:mm:ss".

Your applications are recommended to set the long time pattern to the exact value of interest, instead of attempting to have the time separator replaced. For example, to obtain the pattern h-mm-ss, the application should set "h-mm-ss" specifically.

The following code example displays the value of LongTimePattern for a few cultures.

Imports System
Imports System.Globalization

Public Class SamplesDTFI

   Public Shared Sub Main()

      ' Displays the values of the pattern properties.
      Console.WriteLine(" CULTURE    PROPERTY VALUE")

   End Sub 'Main

   Public Shared Sub PrintPattern(myCulture As [String])

      Dim myDTFI As DateTimeFormatInfo = New CultureInfo(myCulture, False).DateTimeFormat
      Console.WriteLine("  {0}     {1}", myCulture, myDTFI.LongTimePattern)

   End Sub 'PrintPattern 

End Class 'SamplesDTFI

'This code produces the following output. 

'  en-US     h:mm:ss tt 
'  ja-JP     H:mm:ss 
'  fr-FR     HH:mm:ss
