示例

下面的示例演示更改NumberDecimalSeparator属性的效果。The following example demonstrates the effect of changing the NumberDecimalSeparator 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".").
   Int64 myInt = 123456789;
   Console::WriteLine( myInt.ToString( "N", nfi ) );
   
   // Displays the same value with a blank as the separator.
   nfi->NumberDecimalSeparator = " ";
   Console::WriteLine( myInt.ToString( "N", nfi ) );
}

/*
This code produces the following output.
123, 456, 789.00
123, 456, 789 00
*/
using System;
using System.Globalization;

class NumberFormatInfoSample {

   public static void Main() {

      // Gets a NumberFormatInfo associated with the en-US culture.
      NumberFormatInfo nfi = new CultureInfo( "en-US", false ).NumberFormat;

      // Displays a value with the default separator (".").
      Int64 myInt = 123456789;
      Console.WriteLine( myInt.ToString( "N", nfi ) );

      // Displays the same value with a blank as the separator.
      nfi.NumberDecimalSeparator = " ";
      Console.WriteLine( myInt.ToString( "N", nfi ) );

   }
}


/* 
This code produces the following output.

123,456,789.00

      Dim myInt As Int64 = 123456789
      Console.WriteLine(myInt.ToString("N", nfi))

      ' Displays the same value with a blank as the separator.
      nfi.NumberDecimalSeparator = " "
      Console.WriteLine(myInt.ToString("N", nfi))

注解

NumberDecimalSeparator属性与 "E"、"F"、"G"、"N" 和 "R" 标准格式字符串一起使用,以定义将整数与小数位分隔的符号。The NumberDecimalSeparator property is used with the "E", "F", "G", "N", and "R" standard format strings to define the symbol that separates integral from fractional digits. 有关详细信息,请参阅标准数值格式字符串For more information, see Standard Numeric Format Strings.

此属性的初始值派生自 "控制面板" 中 "区域和语言" 项中的设置。The initial value of this property is derived from the settings in the Region and Language item in Control Panel.
