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

static ConditionalExpression^ Condition(
	Expression^ test,
	Expression^ ifTrue,
	Expression^ ifFalse,
	Type^ type
)

Parameters

test
Type: System.Linq.Expressions::Expression^

An Expression to set the Test property equal to.

ifTrue
Type: System.Linq.Expressions::Expression^

An Expression to set the IfTrue property equal to.

ifFalse
Type: System.Linq.Expressions::Expression^

An Expression to set the IfFalse property equal to.

type
Type: System::Type^

A Type to set the Type property equal to.

Return Value

Type: System.Linq.Expressions::ConditionalExpression^

A ConditionalExpression that has the NodeType property equal to Conditional and the Test, IfTrue, and IfFalse properties set to the specified values.

This method allows explicitly unifying the result type of the conditional expression in cases where the types of ifTrue and ifFalse expressions are not equal. Types of both ifTrue and ifFalse must be implicitly reference assignable to the result type. The type is allowed to be Void.
