KMatle Expert Licensed User Longtime User Jan 26, 2017 #1 I've never asked for the reason As known File.WriteList will convert the values to strings. To me this makes no sense as a List can hold any data type. Is there a reason for that behaviour? (Maybe because the written file is a textfile?)

I wasn't precise enough The question is: Why is there a method (File.WriteList) when this method (does not work properly). Properly = Writing a List as it is. Upvote 0

I cant answer this WHY If you think this is an error than you can create a thread in the bug and wishlist forum. Upvote 0

Erel B4X founder Staff member Licensed User Longtime User Jan 27, 2017 #5 File.ReadList reads a text file and returns a list with its lines. File.WriteList writes a list to a text file where each item is written to a separate line. The answer to your question is that this is how these methods were designed (and documented). This behavior will never change. If you want to serialize a list then use B4XSerializator or RAF.WriteB4XObject. The result will be different. You will get a binary file. Upvote 0
