Hi, I'm trying to make a loop that goes through all Session variables and deletes the ones with the prefix "Caract". This is my code:

    for each variable in Session.Contents()
        If left(variable,6) = "Caract" Then
            Session.Contents.Remove(variable)
        End If
    next

I've checked the code many times and it seems to be ok. The problem is that only 1 item is removed. I mean, if I have 5 variables with the prefix I would have to reload the page 5 times to get them all removed. What could be happnin'?

I am not 100% sure, but I think this is caused by the fact that you're modifying a collection (using .Remove) while iterating over it (using For Each). This is not allowed, and usually you'll get an error when you try to do it.

You can fix this by using a regular For loop with a counter. Can't recall if Session.Contents implements a Count property, but if it does, you can use that. E.g.

For i = 0 To Session.Contents().Count - 1
  ' Code to remove goes here
Next


If that doesn't help / work, store the names of the items you want to remove in a separate array, and remove them after you have finished with the For Each loop.

Thanks Imar.
The iteration works, Session.Contents does have a Count property. But before, I could get the name of the session variable using the word "variable" created in the for-each. Now how can I get the name of the variable if Session.Contents(i) returns the value and not the name?:

    for i = 1 to Session.Contents().count
        variablename = 'I need to get the property here
        If left(variablename,6) = "Caract" Then
            Session.Contents.Remove(i)
        End If
    next

I see what you mean;,Interesting problem. I don't think you can. AFAIK, the Contents(i) object does not have a key you can retrieve, as you'd maybe expect.

So, I am afraid this leaves you with the other option: store the keys in an array using For Each, and then use a normal For loop to delete the items.

Sorry if I put you on the wrong track...

Well, i noticed that with the for-each, variables are all deleted. It worked from the begining lol!, the problem is somewhere in the code I was using to check it. Tanks anyway!
