Background: I have a list of objects that are directly linked to the UI in WPF. I need to do some work with those objects, but while I am working with them (asynchronously) I do not want any refreshes on the UI (performance and aesthetic reasons).
So I thought, I might copy the items (using
Collection<T>.CopyTo(T array, int index)
MyUIObject myCopiedList = new MyUIObject[MyObjectsLinkedToTheUI.Count];
foreach (MyUIObject myCopiedItem in myCopiedList)
//while I do this, the UI is still updated
foreach (var myCopiedItem in myCopiedList)
You need to clone them somehow. Either implement ICloneable interface and do all rewriting manually or you can use some hacks/tricks like serializing and deserializing object.
Flow with serialization is something like this:
You'll have a copy of your object that way but it costs more processing power and is prone to some hard to catch errors. But it's an easy way to go. Thing with implementing ICloneable is more reliable but you need to write all that mapping by yourself.
Also, consider using structs instead of classes. Structs are always copied by value not reference. It has some drawbacks so it's up to you if they suit your usage scenario.
