UnaryExpression.IsLiftedToNull Property

.NET Framework 4

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

C++

Copy

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 null, the operator returns null.
