public:
override System::String ^ ToString();
public override string ToString ();
override this.ToString : unit -> string
Public Overrides Function ToString () As String
Returns
A string that represents the value of this instance.
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.

Examples
The following example displays a Decimal value using each of the supported standard numeric format specifiers, together with two custom numeric format strings. In converting the numeric values to strings, the example uses the formatting conventions of the en-US culture.

// Use standard numeric format specifiers.
specifier = "G";
Console.WriteLine("{0}: {1}", specifier, value.ToString(specifier));

Console.WriteLine("{0}: {1}", specifier, value.ToString(specifier));
// Displays: 0,0.000: 16,325.620
specifier = "#,#.00#;(#,#.00#)";

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.
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 or CultureInfo object. The provider
parameter supplies culture-specific information used in formatting. If provider
is null
, the thread current culture is used.
