NumberFormatInfo.NumberNegativePattern 屬性

定義

取得或設定負數值的格式模式。Gets or sets the format pattern for negative numeric values.

public:
 property int NumberNegativePattern { int get(); void set(int value); };
public int NumberNegativePattern { get; set; }
member this.NumberNegativePattern : int with get, set
Public Property NumberNegativePattern As Integer

屬性值

負數值的格式模式。The format pattern for negative numeric values.

例外狀況

屬性已設定為小於 0 或大於 4 的值。The property is being set to a value that is less than 0 or greater than 4.

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

下列範例會使用不同NumberNegativePattern的模式顯示值。The following example displays a value using different NumberNegativePattern patterns.

using namespace System;
using namespace System::Globalization;

int main()
{
   // Create a new NumberFormatinfo.
   NumberFormatInfo^ nfi = gcnew NumberFormatInfo;
   
   // Takes a negative value.
   Int64 value = -1234;
   
   // Displays the value with default formatting.
   Console::WriteLine("{0,-20} {1,-10}", "Default:", 
                          value.ToString("N", nfi));
   
   // Displays the value with other patterns.
   for (int i = 0; i <= 4; i++) {
      nfi->NumberNegativePattern = i;
      Console::WriteLine("{0,-20} {1,-10}", 
                              String::Format("Pattern {0}:", 
                                             nfi->NumberNegativePattern), 
                              value.ToString("N", nfi));
   }
}
// The example displays the following output:
//       Default:             -1,234.00
//       Pattern 0:           (1,234.00)
//       Pattern 1:           -1,234.00
//       Pattern 2:           - 1,234.00
//       Pattern 3:           1,234.00-
//       Pattern 4:           1,234.00 -

備註

NumberNegativePattern屬性會定義使用 "N" 標準數值格式字串格式化的負值格式。The NumberNegativePattern property defines the format of negative values formatted with the "N" standard numeric format string. 此屬性具有下表中的其中一個值。This property has one of the values in the following table. 符號 "-" 為NegativeSign ,而n為數字。The symbol "-" is the NegativeSign and n is a number.

Value 關聯的模式Associated pattern
00 (n)
11 -n-n
22 - n- n
33 n-n-
44 n -n -

InvariantInfo屬性所傳回之不因文化特性而異的預設值為1,代表 "-n",其中n是數位。The default value for the invariant culture returned by the InvariantInfo property is 1, which represents "-n", where n is a number.
