randomize a pagedatacollection
Vote:
Hi all
I'm trying to randomize the content of a pagedatacollection and was wondernig if there is a sorter for this already, i.e FilterPropertySort or something alike. Or maybe put it all in an arraylist and randomize that one? Any suggestions?

Well, since I figured it out (which was quite simple btw) I might aswell post it here and it might help someone out :)
for (int i = 0; i < yourPageDataCollectionObject.Count; i++) {
PageData x = yourPageDataCollectionObject[i];
Random rng = new Random();
int index = rng.Next(yourPageDataCollectionObject.Count - i) + i;
yourPageDataCollectionObject[i] = yourPageDataCollectionObject[index];
yourPageDataCollectionObject[index] = x;
}

That code save me a lot of time, thanks! I did however have some trouble with some objects that as good as always seemed to get the same position after the randomization. I got the a tip in another thread to move the initializing of the Random class outside the loop and that solved it.
