Returns

UnsetValue when the converter cannot produce a value; for example, when value is null or when targetType is not Double or String.

Convert(Object, Type, Object, CultureInfo)

Remarks

UnsetValue may be returned to indicate that the converter produced no value and that the fallback (if available) or default value should be used instead.

Pass null for parameter. This parameter is required by the signature of Convert, and is used by some implementations to provide contextual information to the converter; but it is not used in this class.
