示例

下面的示例演示更改NumberGroupSeparator属性的效果。The following example demonstrates the effect of changing the NumberGroupSeparator 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->NumberGroupSeparator = " ";
   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.NumberGroupSeparator = " ";
      Console.WriteLine( myInt.ToString( "N", nfi ) );

   }
}


/* 
This code produces the following output.

123,456,789.00
123 456 789.00
*/
   
Imports System.Globalization

Class NumberFormatInfoSample

   Public Shared Sub Main()

      ' Gets a NumberFormatInfo associated with the en-US culture.
      Dim nfi As NumberFormatInfo = New CultureInfo("en-US", False).NumberFormat

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

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

   End Sub 'Main

注解

NumberGroupSeparator属性与 "N" 标准格式字符串一起使用,以定义用于分隔整数位组的符号。The NumberGroupSeparator property is used with the "N" standard format string to define the symbol that separates groups of integral 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.
