Assembly:

System.Runtime.dll

Source:

NumberFormatInfo.cs

public string NegativeSign { get; set; }

member this.NegativeSign : string with get, set

Public Property NegativeSign As String

Property Value

String

The string that denotes that the associated number is negative. The default for InvariantInfo is "-".

Exceptions

ArgumentNullException

The property is being set to null.

InvalidOperationException

The property is being set and the NumberFormatInfo object is read-only.

Examples

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. 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(ci));
   }
}
// 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(ci))
      Next
   End Sub
End Module
' The example displays the following output:
'       ‾1
'       ‾16.3
'       ‾106.35
