For information about the predefined format strings recognized by a object and used in numeric formatting operations, see (/dotnet/standard/base-types/standard-numeric-format-strings) and (/dotnet/standard/base-types/custom-numeric-format-strings). The class, which provides information that is used to format numbers, such as the currency, thousands separator, and decimal separator symbols for a particular culture. NET Framework includes the following three predefined implementations to provide culture-specific information that is used in formatting or parsing numeric and date and time values: implementations can also be specified explicitly by methods that have a parameter of type, such as and. For example, the method implicitly uses an implementation that represents the system's current culture. implementations are often used implicitly by formatting and parsing methods. The method is responsible for returning an object of that type. is a callback method: The parsing or formatting method calls it and passes it a object that represents the type of object that the formatting or parsing method expects will provide formatting information. The interface consists of a single method. Typical parsing methods are `Parse` and `TryParse`. Parsing operations convert the string representation of a value to a type with that value. Typical formatting methods are the `ToString` methods of a type, as well as. Formatting operations convert the value of a type to the string representation of that value. interface supplies an object that provides formatting information for formatting and parsing operations.
