NumberFormatInfo.NumberNegativePattern NumberFormatInfo.NumberNegativePattern NumberFormatInfo.NumberNegativePattern NumberFormatInfo.NumberNegativePattern Property

定义

获取或设置负数值的格式模式。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

属性值

负数值的格式模式。The format pattern for negative numeric values.

异常

该属性设置为一个小于 0 或大于 4 的值。The property is being set to a value that is less than 0 or greater than 4.

设置了该属性,但 NumberFormatInfo 对象为只读。The property is being set and the NumberFormatInfo object is read-only.

示例

下面的示例使用不同NumberNegativePattern的模式显示值。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 -

注解

NumberNegativePattern属性定义用 "N" 标准数字格式字符串格式化的负值的格式。The NumberNegativePattern property defines the format of negative values formatted with the "N" standard numeric format string. 此属性具有下表中的值之一。This property has one of the values in the following table. 符号 "-" 是NegativeSignn是一个数字。The symbol "-" is the NegativeSign and n is a number.

Value 关联模式Associated pattern
00 (n)
11 -n-n
22 - n- n
33 n-n-
44 n -n -

InvariantInfo属性返回的固定区域性的默认值为1,表示 "-n",其中n是一个数字。The default value for the invariant culture returned by the InvariantInfo property is 1, which represents "-n", where n is a number.
