SByte.ToString Method (IFormatProvider)

Converts the numeric value of this instance to its equivalent string representation using the specified culture-specific format information.

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

public string ToString(
	IFormatProvider provider


Type: System.IFormatProvider
An object that supplies culture-specific formatting information.

Return Value

Type: System.String
The string representation of the value of this instance, as specified by provider.



The returned string is formatted with the general numeric format specifier ("G").

The provider parameter is an IFormatProvider implementation. Its GetFormat method returns a NumberFormatInfo object that provides culture-specific information about the format of the string returned by this method. If provider is null, the SByte value is formatted using the NumberFormatInfo object of the current culture. The only property of the NumberFormatInfo object that controls the string representation of the SByte value using the general format specifier is NumberFormatInfo.NegativeSign, which defines the character that represents the negative sign.

The provider parameter can be one of the following:

The following example defines a custom NumberFormatInfo object and assigns the "~" character to its NegativeSign property. The example then uses this custom object as well as the NumberFormatInfo object of the invariant culture to format a series of SByte values.

using System;
using System.Globalization;

public class Example
   public static void Main()
      // Define a custom NumberFormatInfo object with "~" as its negative sign.
      NumberFormatInfo nfi = new NumberFormatInfo();
      nfi.NegativeSign = "~";

      // Initialize an array of SByte values.
      sbyte[] bytes = { -122, 17, 124 };

      // Display the formatted result using the custom provider.
      Console.WriteLine("Using the custom NumberFormatInfo object:");
      foreach (sbyte value in bytes)


      // Display the formatted result using the invariant culture.
      Console.WriteLine("Using the invariant culture:");
      foreach (sbyte value in bytes)
// The example displays the following output:
//       Using the custom NumberFormatInfo object:
//       ~122
//       17
//       124
//       Using the invariant culture:
//       -122
//       17
//       124
