NumberFormatInfo.NegativeSign 属性

定义

命名空间:
System.Globalization
程序集:
System.Globalization.dll
程序集:
System.Runtime.dll
程序集:
mscorlib.dll
程序集:
netstandard.dll

获取或设置表示关联数字是负值的字符串。Gets or sets the string that denotes that the associated number is negative.

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

属性值

String

表示关联数字是负值的字符串。The string that denotes that the associated number is negative. InvariantInfo 默认为“-”。The default for InvariantInfo is "-".

例外

ArgumentNullException

该属性设置为 null。The property is being set to null.

InvalidOperationException

设置了该属性，但 NumberFormatInfo 对象为只读。The property is being set and the NumberFormatInfo object is read-only.

示例

下面的示例实例化一个读写 CultureInfo 对象，该对象表示固定区域性，并将上划线字符 (U + 203E) 分配到其 NegativeSign 属性。The following example instantiates a read-write CultureInfo object that represents the invariant culture and assigns the OVERLINE character (U+203E) to its NegativeSign property. 然后，它将使用此 CultureInfo 对象来设置负浮点数的数组的格式。It then uses this CultureInfo object to format an array of negative floating-point numbers.

using System;
using System.Globalization;

public class Example
{
   public static void Main()
   {
      CultureInfo ci = CultureInfo.CreateSpecificCulture("");
      ci.NumberFormat.NegativeSign = "\u203E";
      double[] numbers = { -1.0, -16.3, -106.35 };

      foreach (var number in numbers)
         Console.WriteLine(number.ToString(culture));
   }
}
// The example displays the following output:
//       ‾1
//       ‾16.3
//       ‾106.35

Imports System.Globalization

Module Example
   Public Sub Main()
      Dim ci As CultureInfo = CultureInfo.CreateSpecificCulture("")
      ci.NumberFormat.NegativeSign = ChrW(&h203E)
      Dim numbers() As Double = { -1.0, -16.3, -106.35 }

      For Each number In numbers
         Console.WriteLine(number.ToString(culture))
      Next
   End Sub
End Module
' The example displays the following output:
'       ‾1
'       ‾16.3
'       ‾106.35
