LinqUtilsMergeProjectionAdjustmentsIntoProjectionTFunc Method

Merges the source expression into the destination expression. This is used for projections in the form of a func, to adjust the projection func represented by destination with the expressions in source. The method expects a MemberInitExpression as the body of the lambda for destination and source. the Bindings of the MemberInitExpression in source are then migrated to the Bindings section of the MemberInitExpression of destination. Each binding is a MemberAssignment expression, referring to a member in TTarget and an expression using a parameter representing TSource. The expression can be a MemberAccessExpression or other. If requested, we have to replace the parameter object in the source memberassignment's expressions with the parameter from destination. This is the case in Linq queries, but not in queryspec queries If a binding in source refers to the same member as a binding in destination, it replaces the binding in destination.
