Serialize String-collection object for storing in session variable

Question

In my ASP.Net application, I'm storing a string collection in a Session variable. It was working fine but now I want to change session settings from in-proc to Out Proc. Now I'm having an issue that "Non-Serializable Object Stored in Session". How can I serialize the Sting Collection object before assigning it to a session variable? Please help.

Session["SelectedItems"] =customerGroupsList.SelectedItemsCollection;

I want to change above line of code.

If it's just really a string collection object, then you case use the code below to serialize it and store it as String:

        Session["SelectedItems"] = new System.Web.Script.Serialization.JavaScriptSerializer().Serialize(customerGroupsList.SelectedItemsCollection);
