获取或设置负货币值的格式模式。
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属性值
负货币值的格式模式。 InvariantInfo 的默认值是 0，它表示“($n)”，其中“$”是 CurrencySymbol，n 是一个数字。
例外
属性设置为小于 0 或大于 16 的值。 在 .NET Core 3.1 及更早版本中，如果值大于 15，则会引发此异常。
设置了该属性，但 NumberFormatInfo 对象为只读。
示例
以下示例演示 属性 CurrencyNegativePattern 如何定义负货币值的格式。 它检索在主计算机上定义的所有特定区域性，并显示每个区域性的 CurrencyNegativePattern 属性值、其关联的模式以及格式化为货币值的数字。
