That session variable does not store a string array.
that is what .net means by throwing that error.

cheers.

yes.
store your data as a single string.
since textboxes keep their data as a single string it should be fairly simple to do.

Why don't you try using an Arraylist (or more specifically a Generic List) for your input instead?

If you have not choice but to store your input in a string[] , see if this works,

//this would be your original input array
string[] arrayinput = new string[] { "hello", "world" };

//convert it to a generic list of strings
List<string> test = new List<string>(arrayinput);

//store the above list in session
Session["test"] = test;

//retrieve the list from the session into an string[] array
string[] testarray = ((List<string>)Session["test"]).ToArray();

Kind of circuitous, but it would get the job done.

Thanks.
