The return value is the result of invoking the IConvertible::ToDecimal method of the underlying type of value.
provider enables the user to specify culture-specific conversion information about the contents of value. The base types ignore provider; however, the parameter may be used if value is a user-defined type that implements the IConvertible interface.
The following example defines a Temperature class that implements the IConvertible interface.
The following example shows that when a Temperature object is passed as a parameter to the ToDecimal(Object, IFormatProvider) method, the IConvertible::ToDecimal implementation of the Temperature class is called to perform the conversion.
