The DataFieldConverter class is a TypeConverter object that is typically referenced by the TypeConverterAttribute attribute.

NoteNote

You typically do not access a type converter directly. This implementation of TypeConverter is intended for use by a data-bound control at design time, and is instantiated with a TypeConverterAttribute on a property.
