In this paper, the authors highlight the parsing of numeric strings in .NET framework. A parsing operation converts a string that represents a .NET Framework base type into that base type. The method most commonly used to perform a parsing operation is the parse method. Because parsing is the reverse operation of formatting (which involves converting a base type into its string representation), many of the same rules and conventions apply. Just as formatting uses an object that implements the IFormatProvider interface to provide culture-sensitive formatting information, parsing also uses an object that implements the IFormatProvider interface to determine how to interpret a string representation.
