NumberFormatInfo.PercentGroupSizes 屬性

定義

取得或設定百分比值內小數點左邊數字的各個群組中的位數。Gets or sets the number of digits in each group to the left of the decimal in percent values.

public:
 property cli::array <int> ^ PercentGroupSizes { cli::array <int> ^ get(); void set(cli::array <int> ^ value); };
public int[] PercentGroupSizes { get; set; }
member this.PercentGroupSizes : int[] with get, set
Public Property PercentGroupSizes As Integer()

屬性值

Int32[]

百分比值內小數點左邊數字的各個群組中的位數。The number of digits in each group to the left of the decimal in percent values. InvariantInfo 的預設值為一個只含有一個項目 (已設定為 3) 的一維陣列。The default for InvariantInfo is a one-dimensional array with only one element, which is set to 3.

例外狀況

正在將屬性設定為 nullThe property is being set to null.

將設定此屬性,且此陣列包含小於 0 或大於 9 的項目。The property is being set and the array contains an entry that is less than 0 or greater than 9.

-或--or-

將設定此屬性,且此陣列除了最後一個項目之外包含一個項目,此項目會設定為 0。The property is being set and the array contains an entry, other than the last entry, that is set to 0.

正在設定屬性,而且 NumberFormatInfo 物件為唯讀。The property is being set and the NumberFormatInfo object is read-only.

範例

下列範例示範變更PercentGroupSizes屬性的效果。The following example demonstrates the effect of changing the PercentGroupSizes property.

using namespace System;
using namespace System::Globalization;
int main()
{
   
   // Gets a NumberFormatInfo associated with the en-US culture.
   CultureInfo^ MyCI = gcnew CultureInfo( "en-US",false );
   NumberFormatInfo^ nfi = MyCI->NumberFormat;
   
   // Displays a value with the default separator (S".").
   Double myInt = 123456789012345.6789;
   Console::WriteLine( myInt.ToString( "P", nfi ) );
   
   // Displays the same value with different groupings.
   array<Int32>^mySizes1 = {2,3,4};
   array<Int32>^mySizes2 = {2,3,0};
   nfi->PercentGroupSizes = mySizes1;
   Console::WriteLine( myInt.ToString( "P", nfi ) );
   nfi->PercentGroupSizes = mySizes2;
   Console::WriteLine( myInt.ToString( "P", nfi ) );
}

備註

PercentGroupSizes屬性會與 "P" 標準格式字串搭配使用,以定義整數群組中所顯示的位數。The PercentGroupSizes property is used with the "P" standard format string to define the number of digits that appear in integral groups. 如需詳細資訊,請參閱標準數值格式字串For more information, see Standard Numeric Format Strings. 一維陣列中的每個元素都必須是1到9之間的整數。Every element in the one-dimensional array must be an integer from 1 through 9. 最後一個元素可以是0。The last element can be 0.

陣列的第一個元素會定義緊接在左邊之PercentDecimalSeparator最重要位數群組中的元素數目。The first element of the array defines the number of elements in the least significant group of digits immediately to the left of the PercentDecimalSeparator. 每個後續的元素會參考上一個群組左邊的下一個重要數位群組。Each subsequent element refers to the next significant group of digits to the left of the previous group. 如果陣列的最後一個元素不是0,則會根據陣列的最後一個元素來分組其餘的數位。If the last element of the array is not 0, the remaining digits are grouped based on the last element of the array. 如果最後一個元素為0,則不會將剩餘的數位分組。If the last element is 0, the remaining digits are not grouped.

例如,如果陣列包含 {3,4,5},則數位的分組方式類似 "55,55555,55555,55555,4444,333.00%"。For example, if the array contains { 3, 4, 5 }, the digits are grouped similar to "55,55555,55555,55555,4444,333.00%". 如果陣列包含 {3,4,0},則數位的分組方式類似 "55555555555555555,4444,333.00%"。If the array contains { 3, 4, 0 }, the digits are grouped similar to "55555555555555555,4444,333.00%".
