While setting WCF client service configuration, there is an option “collection type” which defaults to “System.Array”. If I change it to “Generic List”, is there any performance loss?
Over the wire (WCF) there is no difference; the same data will be sent.
At the client, there is very little noticeable performance between
List<T>andT[]in most scenarios. UseList<T>– it is much easier to get it right (adding etc). If you are doing lots of data-binding,BindingList<T>might be useful, but you might want to restrict that to a view-model, not a business object. That does have extra cost (with the events etc).Edit: the biggest “performance cost” will be the time you spend fighting it to add items to arrays (with resize, and the cost there-of); so jump to
List<T>and smile ;-p
