I have your Professional ASP.NET 2.0 book. Very nice. I am implementing a StateServer to manage session data. I used your samples in the book as a model, but all data stored was string data. My implementation stores int data. Everything has compiled, and I can assign int values to the Session data, but I can't seem to format the syntax appropriately to extract it. The following forms give "Specified cast not valid":
int foo = (int)Session["openproject"];
or
int foo = Convert.Int32(Session["openproject"].ToString());
I have implemented a serializable class with private "int" variables for the session object. Help!

Here is the class definition...
[Serializable]
public class Project
{
public int projectid;
public Project()
{
//
// TODO: Add constructor logic here
//
}
public override string ToString()
{
return String.Format("Project Object: {0:c}}", projectid);
}
}
Here is the get/set implemented within the System.Web.UI.Page subclass...
public Project OpenProject
{
get
{
return (Project)Session[OPENPROJECT];
}
set
{
Session[OPENPROJECT] = value;
}
}
