NumberFormatInfo.CurrencyNegativePattern Property

Definition

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

The format pattern for negative currency values. The default for InvariantInfo is 0, which represents "($n)", where "$" is the CurrencySymbol and n is a number.

Exceptions

The property is set to a value that's less than 0 or greater than 16. On .NET Core 3.1 and earlier versions, this exception is thrown if the value is greater than 15.

The property is being set and the NumberFormatInfo object is read-only.

Examples

The following example shows how the CurrencyNegativePattern property defines the format of negative currency values. 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.

Remarks

The CurrencyNegativePattern property is used with the "C" standard format string to define the pattern of negative currency values. For more information, see Standard Numeric Format Strings. This property has one of the values in the following table. The symbol "$" is the CurrencySymbol, the symbol "-" is the NegativeSign, and n is a number.

Value Associated pattern
0 ($n)
1 -$n
2 $-n
3 $n-
4 (n$)
5 -n$
6 n-$
7 n$-
8 -n $
9 -$ n
10 n $-
11 $ n-
12 $ -n
13 n- $
14 ($ n)
15 (n $)
