value

An Object that implements the IConvertible interface.

provider

An IFormatProvider interface implementation that supplies culture-specific formatting information.

A Double number equivalent of value, or zero if value is a null reference ( Nothing in Visual Basic ).

Exception Type	Condition
InvalidCastException	value does not implement IConvertible.

The return value is the result of invoking the IConvertible.ToDouble method of the underlying type of value.

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.
