NumberFormatInfo.CurrencyNegativePattern Property

Definition

Ottiene o imposta il modello di formato per i valori di valuta negativi.Gets or sets the format pattern for negative currency values.

public:
 property int CurrencyNegativePattern { int get(); void set(int value); };
public int CurrencyNegativePattern { get; set; }
member this.CurrencyNegativePattern : int with get, set
Public Property CurrencyNegativePattern As Integer

Property Value

Int32

Modello di formato per i valori di valuta negativi.The format pattern for negative currency values. L'impostazione predefinita per InvariantInfo è 0, che rappresenta "($n)", dove "$" è la proprietà CurrencySymbol e n è un numero.The default for InvariantInfo is 0, which represents "($n)", where "$" is the CurrencySymbol and n is a number.

Exceptions

La proprietà viene impostata su un valore minore di 0 o maggiore di 15.The property is being set to a value that is less than 0 or greater than 15.

La proprietà viene impostata e l'oggetto NumberFormatInfo è di sola lettura.The property is being set and the NumberFormatInfo object is read-only.

Examples

Nell'esempio seguente viene illustrato il modo in cui la proprietà CurrencyNegativePattern definisce il formato dei valori di valuta negativi.The following example shows how the CurrencyNegativePattern property defines the format of negative currency values. Recupera tutte le impostazioni cultura specifiche definite nel computer host e visualizza il valore della proprietà CurrencyNegativePattern, il modello associato e un numero formattato come valore di valuta.It retrieves all the specific cultures that are defined on the host computer and displays each culture's CurrencyNegativePattern property value, its associated pattern, and a number formatted as a currency value.
