CultureInfo.NumberFormat Property
[ This article is for Windows Phone 8 developers. If you’re developing for Windows 10, see the latest documentation. ]
Gets or sets a NumberFormatInfo object that defines the culturally appropriate format for converting numbers, currency values, and percentages to strings.
Assembly: mscorlib (in mscorlib.dll)
Property Value
Type: System.Globalization.NumberFormatInfoAn object that defines the culturally appropriate format for outputting numbers, currency values, and percentages.
| Exception | Condition |
|---|---|
| ArgumentNullException | The property is being set to Nothing. |
| InvalidOperationException | The NumberFormat property or any of the NumberFormatInfo properties is being set, and the CultureInfo is read-only. |
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.
Version Notes
Windows Phone
If Name is fr, and the CurrencySymbol property of NumberFormat is set to USD, NumberFormat throws a NotSupportedException.The following example shows that Clone method also clones the DateTimeFormatInfo and NumberFormatInfo objects associated with the CultureInfo object.
