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.
