Gets or sets a NumberFormatInfo object that defines the culturally appropriate format for converting numbers, currency values, and percentages to strings.
(in mscorlib.dll)
Visual Basic (Declaration)
Public Overridable Property NumberFormat As NumberFormatInfo
Get
Set
Dim instance As CultureInfo
Dim value As NumberFormatInfo
value = instance.NumberFormat
instance.NumberFormat = value
public virtual NumberFormatInfo NumberFormat { get; set; }
The user might choose to override some of the values associated with the current system culture. For example, the user might choose to display the date in a different format or to use a currency other than the default for the culture. The NumberFormatInfo object returned by the NumberFormat property of the current culture reflects these overrides.
The values of the DateTimeFormat property and the NumberFormat property are not calculated until the property is accessed. If the application changes the current culture to a new culture while the application is running and then accesses the DateTimeFormat or NumberFormat property, the application retrieves the defaults for the new culture rather than the overrides for the original culture. To preserve the overrides for the original current culture, the application should access the DateTimeFormat and NumberFormat properties before changing the current culture.
The following example shows that Clone method also clones the DateTimeFormatInfo and NumberFormatInfo objects associated with the CultureInfo object.
Imports System.Globalization
Public Class Example
Public Shared Sub Demo(ByVal outputBlock As System.Windows.Controls.TextBlock)
' Creates and initializes a CultureInfo object.
Dim myCI As New CultureInfo("en-US")
' Clones myCI and modifies the DTFI and NFI instances associated with the clone.
Dim myCIclone As CultureInfo = CType(myCI.Clone(), CultureInfo)
myCIclone.DateTimeFormat.AMDesignator = "a.m."
myCIclone.NumberFormat.CurrencySymbol = "USD"
myCIclone.NumberFormat.NumberDecimalDigits = 4
' Displays the properties of the DTFI and NFI instances associated with the original and with the clone.
outputBlock.Text &= "DTFI/NFI PROPERTY" + ControlChars.Tab + "ORIGINAL" + ControlChars.Tab + "MODIFIED CLONE" & vbCrLf
outputBlock.Text += String.Format("DTFI.AMDesignator" + ControlChars.Tab + "{0}" + ControlChars.Tab + ControlChars.Tab + "{1}", myCI.DateTimeFormat.AMDesignator, myCIclone.DateTimeFormat.AMDesignator) & vbCrLf
outputBlock.Text += String.Format("NFI.CurrencySymbol" + ControlChars.Tab + "{0}" + ControlChars.Tab + ControlChars.Tab + "{1}", myCI.NumberFormat.CurrencySymbol, myCIclone.NumberFormat.CurrencySymbol) & vbCrLf
outputBlock.Text += String.Format("NFI.NumberDecimalDigits" + ControlChars.Tab + "{0}" + ControlChars.Tab + ControlChars.Tab + "{1}", myCI.NumberFormat.NumberDecimalDigits, myCIclone.NumberFormat.NumberDecimalDigits) & vbCrLf
End Sub
End Class
' This example produces the following output.
' DTFI/NFI PROPERTY ORIGINAL MODIFIED CLONE
' DTFI.AMDesignator AM a.m.
' NFI.CurrencySymbol $ USD
' NFI.NumberDecimalDigits 2 4
