Gets or sets a NumberFormatInfo that defines the culturally appropriate format of displaying numbers, currency, and percentage.
(in mscorlib.dll)
Visual Basic (Declaration)
Public Overridable Property NumberFormat As NumberFormatInfo
Dim instance As CultureInfo
Dim value As NumberFormatInfo
value = instance.NumberFormat
instance.NumberFormat = value
public virtual NumberFormatInfo NumberFormat { get; set; }
public:
virtual property NumberFormatInfo^ NumberFormat {
NumberFormatInfo^ get ();
void set (NumberFormatInfo^ value);
}
public function get NumberFormat () : NumberFormatInfo
public function set NumberFormat (value : NumberFormatInfo)
A NumberFormatInfo can be created only for the invariant culture or for specific cultures, not for neutral cultures. For more information, see the description of the CultureInfo class.
Overrides
The user might choose to override some of the values associated with the current culture of Windows through the regional and language options portion of Control Panel. 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.
If UseUserOverride is true and the specified culture matches the current culture of Windows, the CultureInfo uses those overrides, including user settings for the properties of the DateTimeFormatInfo instance returned by the DateTimeFormat property, and the properties of the NumberFormatInfo instance returned by the NumberFormat property. If the user settings are incompatible with the culture associated with the CultureInfo, for example, if the selected calendar is not one of the OptionalCalendars, the results of the methods and the values of the properties are undefined.
The values of the DateTimeFormat property and the NumberFormat property are not calculated until the user accesses the property. If the user uses the Control Panel to change 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. not 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 code example shows that CultureInfo.Clone also clones the DateTimeFormatInfo and NumberFormatInfo instances associated with the CultureInfo.
