NumberFormatInfo.PercentGroupSizes 属性
获取或设置百分比值中小数点左边的每一组的位数。
**命名空间:**System.Globalization
**程序集:**mscorlib(在 mscorlib.dll 中)
语法
声明
Public Property PercentGroupSizes As Integer()
用法
Dim instance As NumberFormatInfo
Dim value As Integer()
value = instance.PercentGroupSizes
instance.PercentGroupSizes = value
public int[] PercentGroupSizes { get; set; }
public:
property array<int>^ PercentGroupSizes {
array<int>^ get ();
void set (array<int>^ value);
}
/** @property */
public int[] get_PercentGroupSizes ()
/** @property */
public void set_PercentGroupSizes (int[] value)
public function get PercentGroupSizes () : int[]
public function set PercentGroupSizes (value : int[])
属性值
百分比值中小数点左边的每一组的位数。InvariantInfo 的默认值是一个一维数组,该数组只包含一个设置为 3 的元素。
异常
异常类型 | 条件 |
---|---|
该属性被设置为 空引用(在 Visual Basic 中为 Nothing)。 |
|
试图设置该属性,但此数组包含一个小于 0 或大于 9 的项。 - 或 - 试图设置该属性,但此数组包含一个设置为 0 的项(最后一项除外)。 |
|
设置该属性,并且 NumberFormatInfo 是只读的。 |
备注
一维数组中的每个元素都必须是从 1 到 9 的整数。最后一个元素可以是 0。
数组的第一个元素定义紧靠 PercentDecimalSeparator 左边的最低有效数字组中的元素数。后面的每个元素指示前一组左边的下一个有效数字组。如果数组的最后一个元素不为 0,则将根据数组中的最后一个元素对其余的数字进行分组。如果最后一个元素为 0,则不对其余数字进行分组。
例如,如果该数组包含 { 3, 4, 5 },则对数字的分组将类似于“55,55555,55555,55555,4444,333.00%”。如果该数组包含 { 3, 4, 0 },则对数字的分组将类似于“55555555555555555,4444,333.00%”。
