DateTimeFormatInfo.LongTimePattern Property

Gets or sets the custom format string for a long time value.

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

'Declaration
Public Property LongTimePattern As String

Property Value

Type: System.String
The format pattern for a long time value.

ExceptionCondition
ArgumentNullException

The property is being set to Nothing.

InvalidOperationException

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

The LongTimePattern property defines the culture-specific format of date strings that are returned by calls to the DateTime.ToString and DateTimeOffset.ToString methods and by composite format strings that are supplied the "T" standard format string.

We recommend that you set the time separator in the long time pattern to an exact string instead of using the time separator placeholder. For example, to obtain the pattern h-mm-ss, set the long date pattern to "h-mm-ss".

The following 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")
      PrintPattern("en-US")
      PrintPattern("ja-JP")
      PrintPattern("fr-FR")

   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. 

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