      PrintPattern(outputBlock, "en-US")
      PrintPattern(outputBlock, "ar-EG")
      PrintPattern(outputBlock, "fr-FR")
   End Sub 

   Public Shared Sub PrintPattern(ByVal outputBlock As System.Windows.Controls.TextBlock, ByVal myCulture As [String])
      Dim myDTFI As DateTimeFormatInfo = New CultureInfo(myCulture).DateTimeFormat
      outputBlock.Text += String.Format("  {0}     {1}", myCulture, myDTFI.LongTimePattern) & vbCrLf
   End Sub
End Class
' This example displays the following output:

      PrintPattern(outputBlock, "en-US");
      PrintPattern(outputBlock, "ar-EG");
