Converts the numeric value of this instance to its equivalent string representation, using the specified format.

public string ToString(
	string format


Type: System.String

A standard or custom numeric format string.

Return Value

Type: System.String

The string representation of the value of this instance as specified by format.

Exception Condition

format is invalid.

The ToString(String) method formats an SByte value in a specified format by using the conventions of the current culture. If you want to use the default ("G", or general) format or specify a different culture, use the other overloads of the ToString method, as follows:

To use format

For culture

Use the overload

Default ("G") format

Default (current) culture


Default ("G") format

A specific culture


A specific format

A specific culture

ToString(String, IFormatProvider)

The format parameter can be any valid standard numeric format specifier, or any combination of custom numeric format specifiers. If format is equal to String.Empty or is null, the return value of the current SByte object is formatted with the general format specifier ("G"). If format is any other value, the method throws a FormatException.

The .NET Framework provides extensive formatting support, which is described in greater detail in the following formatting topics:

The format of the returned string is determined by the NumberFormatInfo object for the current culture. Depending on the format parameter, this object controls symbols such as the negative sign, the group separator, and the decimal point symbol in the output string. To provide formatting information for cultures other than the current culture, call the ToString(String, IFormatProvider) overload.

The following example initializes an array of SByte values and displays them by using each standard format string and some custom format strings.

using System;
using System.Globalization;

public class Example
   public static void Main()
      sbyte[] values = { -124, 0, 118 };
      string[] specifiers = { "G", "C", "D3", "E2", "e3", "F", 
                              "N", "P", "X", "00.0", "#.0", 
                              "000;(0);**Zero**" };

      foreach (sbyte value in values)
         foreach (string specifier in specifiers)
            Console.WriteLine("{0}: {1}", specifier, value.ToString(specifier));
// The example displays the following output:
//       G: -124
//       C: ($124.00)
//       D3: -124
//       E2: -1.24E+002
//       e3: -1.240e+002
//       F: -124.00
//       N: -124.00
//       P: -12,400.00 %
//       X: 84
//       00.0: -124.0
//       #.0: -124.0
//       000;(0);**Zero**: (124)
//       G: 0
//       C: $0.00
//       D3: 000
//       E2: 0.00E+000
//       e3: 0.000e+000
//       F: 0.00
//       N: 0.00
//       P: 0.00 %
//       X: 0
//       00.0: 00.0
//       #.0: .0
//       000;(0);**Zero**: **Zero**
//       G: 118
//       C: $118.00
//       D3: 118
//       E2: 1.18E+002
//       e3: 1.180e+002
//       F: 118.00
//       N: 118.00
//       P: 11,800.00 %
//       X: 76
//       00.0: 118.0
//       #.0: 118.0
//       000;(0);**Zero**: 118
