Question

I use this code to return a list of object to store them in out-proc session :

Session["Data"] = DataContext.ObjectSet.Select(rec => new { Title = rec.Title , Count = rec.Count });

But as you know , we can not store un-serializable class in a out-proc session, Is there any way to do this ?
Please do not say me to define its class, I am looking for a backdoor in C# or a tricks to do this

Thanks

One easy way is to convert to an array object

Session["Data"] = DataContext.ObjectSet
                      .Select(rec => new { Title = rec.Title , Count = rec.Count })
                      .ToArray();

You can even convert it to a List oibject and serialize it into your own object

var data = DataContext.ObjectSet
             .Select(rec => new SessionData() { Title = rec.Title , Count = rec.Count })
             .ToList();

System.Web.Script.Serialization.JavaScriptSerializer oSerializer = 
     new System.Web.Script.Serialization.JavaScriptSerializer();

Session["Data"] = oSerializer.Serialize(data);

and using

public class SessionData {
   public string Title { get; set; }
   public int Count { get; set; }
}

But holding such object in a session… you would probably doing things wrong no? Imagine in a given time you will have 1000 records for that list…
