示例

下面的示例演示更改 NumberDecimalSeparator 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->NumberDecimalSeparator = " ";
   Console::WriteLine( myInt.ToString( "N", nfi ) );
}

/*

注解

属性 NumberDecimalSeparator 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数字分开的符号。 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。
