size of arraylist in bytes

hi

is there a way to find out the size (in bytes) of an arraylist and all of its contents?

(i need to know the file-size before I serialize the arraylist.)

thanks!

Why don't you serialize it first and then measure the size...
TransBindCommented:
Use the FileInfo class:
FileInfo info = new FileInfo(path);
long fileSize = info.Length;

is sizeof(arraylist) any help?

There is no way to get the size of non value types. Maybe you can try to calculate it yourself based on the knowledge how many and what objects are in the ArrayList and also by seeing how much bytes the ArrayList data takes. So just make some tests like serializing the ArrayList empty, then with 1, 2 objects and you will figure it out. If you use objects like strings, I suppose it will be harder, But if you store objects like int, it will work.
