NumberFormatInfo.CurrencyNegativePattern 屬性
定義
重要

取得或設定負數貨幣值的格式模式。
public:
property int CurrencyNegativePattern { int get(); void set(int value); };public int CurrencyNegativePattern { get; set; }member this.CurrencyNegativePattern : int with get, setPublic Property CurrencyNegativePattern As Integer屬性值
負數貨幣值的格式模式。 InvariantInfo 的預設值為 0，代表 "($n)"；其中 "$" 為 CurrencySymbol，而 n 為數值。
例外狀況
屬性會設定為小於 0 或大於 16 的值。 在 .NET Core 3.1 和舊版上，如果值大於 15，就會擲回此例外狀況。
正在設定屬性，而且 NumberFormatInfo 物件為唯讀。
範例
下列範例示範 屬性如何 CurrencyNegativePattern 定義負值的格式。 它會擷取主計算機上定義的所有特定文化特性，並顯示每個文化特性的 CurrencyNegativePattern 屬性值、其相關聯的模式，以及格式化為貨幣值的數位。

備註
屬性 CurrencyNegativePattern 會與 「C」 標準格式字串搭配使用，以定義負值模式。 如需詳細資訊，請參閱標準數值格式字串。 此屬性具有下表中的其中一個值。 符號 “$” 是 CurrencySymbol，符號 “-” 是 NegativeSign，而且 n 是數位。
| 值 | 相關聯的模式 |
|---|---|
| 0 | ($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 $) |
| 16 | $- n |
