NumberFormatInfo.NegativeSign Property


Gets or sets the string that denotes that the associated number is negative.

Namespace:   System.Globalization
Assembly:  mscorlib (in mscorlib.dll)

public string NegativeSign { get; set; }

Property Value

Type: System.String

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

Exception Condition

The property is being set to null.


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

This property is used in both formatting and parsing operations. For more information on its use in formatting operations, see the Standard Numeric Format Strings and Custom Numeric Format Strings topics.

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)
// The example displays the following output:
//       ‾1
//       ‾16.3
//       ‾106.35
