provider enables the user to specify culture-specific conversion information about the contents of value. For example, if value is a String that represents a number, provider could supply culture-specific information about the notation used to represent that number.
The base types ignore provider; however, it is honored if value is a user-defined type that implements the IConvertible interface.
