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.
Implements
IConvertible::ToString(IFormatProvider^)The ToString(IFormatProvider^) method formats a Single 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 | |
A specific format | Default (current) culture | |
A specific format | A specific culture |
The return value can be PositiveInfinitySymbol, NegativeInfinitySymbol, NaNSymbol, or a string of the form:
[sign]integral-digits[.[fractional-digits]][e[sign]exponential-digits]
Optional elements are framed in square brackets ([ and ]). Elements containing the term "digits" consist of a series of numeric characters ranging from 0 to 9. The following table lists each element.
Element | Description |
|---|---|
sign | A negative sign or positive sign symbol. |
integral-digits | A series of digits specifying the integral part of the number. Integral-digits can be absent if there are fractional-digits. |
'.' | A culture-specific decimal point symbol. |
fractional-digits | A series of digits specifying the fractional part of the number. |
'e' | A lowercase character 'e', indicating exponential (scientific) notation. |
exponential-digits | A series of digits specifying an exponent. |
Some examples of the return value are "100", "-123,456,789", "123.45e+6", "500", "3.1416", "600", "-0.123", and "-Infinity".
The .NET Framework 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 GetFormat method returns a NumberFormatInfo object. Typically, provider is a CultureInfo object or a NumberFormatInfo object. The provider parameter supplies culture-specific information used in formatting. If provider is null, the return value is formatted using the NumberFormatInfo data for the current culture.
To convert a Single value to its string representation using a specified culture and a specific format string, call the Single::ToString(String^, IFormatProvider^) method.
The following example displays the string representation of two Single values using CultureInfo objects that represent several different cultures.
