Property Value

Type: System::Boolean

true if the operator's return type is lifted to a nullable type; otherwise, false.

An operator call is lifted if the operator expects a non-nullable operand but a nullable operand is passed to it. If the value of IsLiftedToNull is true, the operator returns a nullable type and if the nullable operand evaluates to null, the operator returns null.
