what should be prefered: array of typename or TList? With array of you should take care of memory yourself With tlist you must use typecasting or make an inherited version of tlist Wat is the best way to use? |

There is no "this is the best for all" in this question. I mostly use array of, because it's easy to handle and you don't have to do any typecasts. But especially if you do many operations on the list itself during runtime (sorting, removing items, adding items inbetween) a TList is the better way to go, since it already comes with many needed functions. |

I generally follow the rule below. If I want to list TObject/TPersistent instances, I use TObjectList If I use primitive types (Int, String, whatever) I use dynamic arrays. The reason for using TObjectList, is that I clears its own memory, and the mem of the object instances inside it when you free it. Very handy when you have hundereds of objects to keep track of.
