 override System::String ^ ToString();

public override string ToString ();

override this.ToString : unit -> string

Public Overrides Function ToString () As String

Returns

String

The string representation of the value of this instance, consisting of a negative sign if the value is negative, and a sequence of digits ranging from 0 to 9 with no leading zeroes.

Examples

The following example displays an SByte value using the default ToString() method. It also displays the string representations of the SByte value that results from using a number of standard format specifiers. The examples are displayed using the formatting conventions of the en-US culture.

using System;

public class Example
{
   public static void Main()
   {
      sbyte value = -123;
      // Display value using default ToString method.
      Console.WriteLine(value.ToString());            // Displays -123
      // Display value using some standard format specifiers.
      Console.WriteLine(value.ToString("G"));         // Displays -123
      Console.WriteLine(value.ToString("C"));         // Displays ($-123.00)
      Console.WriteLine(value.ToString("D"));         // Displays -123
      Console.WriteLine(value.ToString("F"));         // Displays -123.00
      Console.WriteLine(value.ToString("N"));         // Displays -123.00
      Console.WriteLine(value.ToString("X"));         // Displays 85
   }
}

let value = -123y
// Display value using default ToString method.
printfn $"{value.ToString()}"               // Displays -123
// Display value using some standard format specifiers.
printfn $"""{value.ToString "G"}"""         // Displays -123
printfn $"""{value.ToString "C"}"""         // Displays ($-123.00)
printfn $"""{value.ToString "D"}"""         // Displays -123
printfn $"""{value.ToString "F"}"""         // Displays -123.00
printfn $"""{value.ToString "N"}"""         // Displays -123.00
printfn $"""{value.ToString "X"}"""         // Displays 85

Module Example
   Public Sub Main()
      Dim value As SByte = -123
      ' Display value using default ToString method.
      Console.WriteLine(value.ToString())            ' Displays -123
      ' Display value using some standard format specifiers.
      Console.WriteLine(value.ToString("G"))         ' Displays -123
      Console.WriteLine(value.ToString("C"))         ' Displays ($-123.00)
      Console.WriteLine(value.ToString("D"))         ' Displays -123
      Console.WriteLine(value.ToString("F"))         ' Displays -123.00
      Console.WriteLine(value.ToString("N"))         ' Displays -123.00
      Console.WriteLine(value.ToString("X"))         ' Displays 85
   End Sub
End Module

Remarks

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

To use format	For culture	Use the overload
Default ("G") format	A specific culture	ToString(IFormatProvider)
A specific format	Default (current) culture	ToString(String)
A specific format	A specific culture	ToString(String, IFormatProvider)

The return value is formatted using the general numeric format specifier ("G") The string representation of the SByte value includes a negative sign if its value is negative, and a sequence of digits ranging from 0 to 9 without leading zeros. The negative sign is defined by the NumberFormatInfo object for the current culture.

To define the formatting of the signed byte value's string representation, call the ToString(String) method.

ToString(IFormatProvider)

Examples

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)
         Console.WriteLine(value.ToString(nfi));

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

    printfn $"{value.ToString nfi}"

printfn ""
      
// Display the formatted result using the invariant culture.

Remarks

The ToString(IFormatProvider) method formats an SByte value in the default ("G", or general) format of a specified culture. If you want to specify a different format or the current 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	ToString()
A specific format	Default (current) culture	ToString(String)
A specific format	A specific culture	ToString(String, IFormatProvider)

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:

A CultureInfo object that represents the culture that supplies formatting information.
The NumberFormatInfo object that supplies formatting information.
A custom object that implements IFormatProvider. Its GetFormat method returns the NumberFormatInfo object that supplies formatting information.

Remarks

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	ToString()
Default ("G") format	A specific culture	ToString(IFormatProvider)
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.

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

For more information about numeric format specifiers, see Standard Numeric Format Strings and Custom Numeric Format Strings.
For more information about support for formatting in .NET, see Formatting Types.

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.

Remarks

The ToString(String, IFormatProvider) method formats an SByte value in a specified format of a specified culture. If you want to use default format or culture settings, use the other overloads of the ToString method, as follows:

To use format	For culture	Use the overload
Default ("G") format	Default (current) culture	ToString()
Default ("G") format	A specific culture	ToString(IFormatProvider)
A specific format	Default (current) culture	ToString(String)

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

For more information about numeric format specifiers, see Standard Numeric Format Strings and Custom Numeric Format Strings.
For more information about support for formatting in .NET, see Formatting Types.

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. When the ToString(String, IFormatProvider) method is invoked, it calls the provider parameter's IFormatProvider.GetFormat method and passes it a Type object that represents the NumberFormatInfo type. The GetFormat method then returns the NumberFormatInfo object that provides information for formatting the value parameter, such as the negative sign symbol, the group separator symbol, or the decimal point symbol. There are three ways to use the provider parameter to supply formatting information to the ToString(String, IFormatProvider) method:

You can pass a CultureInfo object that represents the culture that supplies formatting information. Its GetFormat method returns the NumberFormatInfo object that provides numeric formatting information for that culture.
You can pass the actual NumberFormatInfo object that provides numeric formatting information. (Its implementation of GetFormat just returns itself.)
You can pass a custom object that implements IFormatProvider. Its GetFormat method instantiates and returns the NumberFormatInfo object that provides formatting information.

If provider is null, the formatting of the returned string is based on the NumberFormatInfo object of the current culture.
