UnaryExpression.IsLiftedToNull Property

Microsoft Silverlight will reach end of support after October 2021. Learn more.

Gets a value that indicates whether the expression tree node represents a lifted call to an operator whose return type is lifted to a nullable type.

Namespace:  System.Linq.Expressions
Assembly:  System.Core (in System.Core.dll)

Syntax

'Declaration
Public ReadOnly Property IsLiftedToNull As Boolean
public bool IsLiftedToNull { get; }

Property Value

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

Remarks

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 nulla null reference (Nothing in Visual Basic), the operator returns nulla null reference (Nothing in Visual Basic).
