NumberFormatInfo.CurrencyNegativePattern 属性

定义

命名空间:

System.Globalization

程序集:

System.Runtime.dll

Source:

NumberFormatInfo.cs

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, set

Public Property CurrencyNegativePattern As Integer

属性值

Int32

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

ArgumentOutOfRangeException

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。

InvalidOperationException

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。
