範例

下列範例示範變更 NumberGroupSeparator 屬性的效果。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

End Class


'This code produces the following output.

'

'123,456,789.00

'123 456 789.00


備註

NumberGroupSeparator 屬性會與 "N" 標準格式字串搭配使用,以定義分隔整數數位群組的符號。The NumberGroupSeparator property is used with the "N" standard format string to define the symbol that separates groups of integral digits. 如需詳細資訊,請參閱標準數值格式字串For more information, see Standard Numeric Format Strings.

這個屬性的初始值衍生自 [控制台] 中 [地區和語言] 專案的設定。The initial value of this property is derived from the settings in the Region and Language item in Control Panel.
