NumberFormatInfo.NumberNegativePattern 属性
获取或设置负数值的格式模式。
**命名空间:**System.Globalization
**程序集:**mscorlib（在 mscorlib.dll 中）
语法
声明
Public Property NumberNegativePattern As Integer
用法
Dim instance As NumberFormatInfo
Dim value As Integer
value = instance.NumberNegativePattern
instance.NumberNegativePattern = value
public int NumberNegativePattern { get; set; }
public:
property int NumberNegativePattern {
int get ();
void set (int value);
}
/** @property */
public int get_NumberNegativePattern ()
/** @property */
public void set_NumberNegativePattern (int value)
public function get NumberNegativePattern () : int
public function set NumberNegativePattern (value : int)
属性值
负数值的格式模式。InvariantInfo 的默认值为 1，这表示“-n”，其中 n 是一个数字。
异常
| 异常类型 | 条件 |
|---|---|
该属性被设置为小于 0 或大于 4 的值。 |
|
设置该属性，并且 NumberFormatInfo 是只读的。 |
备注
该属性可以具有下表中列出的其中一个值。符号“-”是 NegativeSign，并且 n 是一个数字。
