 property cli::array <int> ^ NumberGroupSizes { cli::array <int> ^ get(); void set(cli::array <int> ^ value); };

public int[] NumberGroupSizes { get; set; }

member this.NumberGroupSizes : int[] with get, set

Public Property NumberGroupSizes As Integer()

属性值

Int32[]

数值中小数点左边每一组的位数。 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。

例外

ArgumentNullException

该属性设置为 null。

ArgumentException

设置了该属性，但数组包含一个小于 0 或大于 9 的项。

或

设置了该属性，但数组包含一个设置为 0 的项（最后一项除外）。

InvalidOperationException

设置了该属性，但 NumberFormatInfo 对象为只读。

示例

以下示例演示更改 NumberGroupSizes 属性的效果。

using namespace System;

注解

属性的值 NumberGroupSizes 会影响使用“N”设置格式的数字值的结果。如果使用自定义数值格式字符串或其他标准数值格式字符串，则会忽略属性的值 NumberGroupSizes 。

一维数组中的每个元素必须是 1 到 9 的整数。最后一个元素可以为 0。

数组的第一个元素定义紧邻左侧的最小有效数字组中的 NumberDecimalSeparator元素数。每个后续元素都引用上一组左侧的下一组重要数字。如果数组的最后一个元素不是 0，则根据数组的最后一个元素对剩余数字进行分组。如果最后一个元素为 0，则不会对剩余数字进行分组。

例如，如果数组包含 { 3， 4， 5 }，则数字分组类似于“55,55555,55555,55555,4444,333.00”。如果数组包含 { 3， 4， 0 }，则数字分组类似于“5555555555555555,4444,333.00”。
