Examples

The following example displays a Decimal value using the default ToString() method. It also displays the string representations of the Decimal value that result from using a number of standard format specifiers.

decimal value = -16325.62m;
// Display value using default ToString method.
Console.WriteLine(value.ToString());            // Displays -16325.62
// Display value using some standard format specifiers.
Console.WriteLine(value.ToString("G"));         // Displays -16325.62
Console.WriteLine(value.ToString("C"));         // Displays ($16,325.62)
Console.WriteLine(value.ToString("F"));         // Displays -16325.62

let value = -16325.62m
// Display value using default ToString method.
printfn $"{value.ToString()}"            // Displays -16325.62
// Display value using some standard format specifiers.
printfn $"""{value.ToString "G"}"""      // Displays -16325.62
printfn $"""{value.ToString "C"}"""      // Displays ($16,325.62)
printfn $"""{value.ToString "F"}"""      // Displays -16325.62

Dim value As Decimal = -16325.62d
' Display value using default ToString method.
Console.WriteLine(value.ToString())            ' Displays -16325.62
' Display value using some standard format specifiers.
Console.WriteLine(value.ToString("G"))         ' Displays -16325.62
Console.WriteLine(value.ToString("C"))         ' Displays ($16,325.62)
Console.WriteLine(value.ToString("F"))         ' Displays -16325.62

The following example displays the amount of money in an account.

   public ref class PiggyBank
   {
   public:
      void AddPenny()
      {
         MyFortune = Decimal::Add( MyFortune, (Decimal).01 );
      }

      virtual System::String^ ToString() override
      {
         return MyFortune.ToString("C")+" in piggy bank";
      }

   protected:
      Decimal MyFortune;
   };
}

class PiggyBank {
    public void AddPenny() {
        MyFortune = Decimal.Add(MyFortune, .01m);
    }

    public override string ToString() {
        return MyFortune.ToString("C")+" in piggy bank";
    }

    protected decimal MyFortune;
}

type PiggyBank() =
    let mutable myFortune = 0m

    member _.AddPenny() =
        myFortune <- Decimal.Add(myFortune, 0.01m)

    override _.ToString() =
        $"{myFortune:C} in piggy bank"

Class PiggyBank

    Public Sub AddPenny()
        MyFortune = [Decimal].Add(MyFortune, 0.01D)
    End Sub

    Public Overrides Function ToString() As String
        Return MyFortune.ToString("C") + " in piggy bank"
    End Function

    Protected MyFortune As Decimal
End Class

Remarks

The ToString() method formats a Decimal 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)

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

Remarks

The ToString(IFormatProvider) method formats a Decimal 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)

.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 formatting, see Formatting Types.

The provider parameter is an IFormatProvider implementation whose IFormatProvider.GetFormat method returns a NumberFormatInfo object. Typically, provider is a NumberFormatInfo object or a CultureInfo object. The provider parameter supplies culture-specific information used in formatting. If provider is null, the thread current culture is used.

To convert a Decimal value to its string representation using a specified culture and a specific format string, call the Decimal.ToString(String, IFormatProvider) method.

Remarks

The ToString(String) method formats a Decimal 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 ToString method uses the standard or custom numeric format string specified by the format parameter to convert the value of the current instance into its string representation. The format parameter can be any valid standard numeric format specifier except for D, R, and X, as well as any combination of custom numeric format specifiers. If format is null or an empty string, the return value of this instance is formatted with the general numeric format specifier (G).

.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 formatting, see Formatting Types.

The return value is formatted by using the NumberFormatInfo object for the current culture. To apply the formatting conventions of a specified culture, call the ToString(String, IFormatProvider) method.

Remarks

The ToString(String, IFormatProvider) method formats a Decimal 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)

The format parameter can be any valid standard numeric format specifier except for D, R, and X, as well as any combination of custom numeric format specifiers. If format is null or an empty string, the return value for this instance is formatted with the general numeric format specifier ("G").

.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.

The provider parameter is an IFormatProvider implementation whose IFormatProvider.GetFormat method returns a NumberFormatInfo object. Typically, provider is a NumberFormatInfo or CultureInfo object. The provider parameter supplies culture-specific information used in formatting. If provider is null, the thread current culture is used.
