public:
 property System::String ^ NumberDecimalSeparator { System::String ^ get(); void set(System::String ^ value); };
public string NumberDecimalSeparator { get; set; }
member this.NumberDecimalSeparator : string with get, set
Public Property NumberDecimalSeparator As String

属性值

在数值中用作小数分隔符的字符串。 InvariantInfo 默认为“.”。

例外

该属性设置为 null

设置了该属性,但 NumberFormatInfo 对象为只读。

该属性被设置为空字符串。

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 ) );
}

/*
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 ) );
   }
}
