示例

下面的示例演示更改 NumberGroupSeparator 属性的效果。

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 ) );
}

/*

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;

      nfi.NumberGroupSeparator = " ";
      Console.WriteLine( myInt.ToString( "N", nfi ) );

注解

属性 NumberGroupSeparator 与“N”标准格式字符串一起使用，用于定义分隔整型数字组的符号。 有关详细信息，请参阅标准数值格式字符串。

此属性的初始值派生自控制面板的“区域和语言”项中的设置。
