Setting session variables in a class is setting all of them, not just one - session

Question

I have been researching a way to set session variables for my Web App to store the logged in user's info. I have made a lot of progress, being a novice, but I am stumped as to why setting the variables will set all of them and not just the one specified. Can someone point out my mistake(s), please? Thank you!!

I don't think you are setting your session keys correctly. In your static class you have a property setter that is essentially session Session[""]=Some Value for all members. You do not need to set the key to the name of the private member in .net 3.5 you do not even need the private member. You could also just stuff the whole session object in and not worry about each member.
Then just access a Current instantiator of the properties as in
MySession.Current.UserName="guest";
public class MySession
{
private const string _SessionName = "__MY_SESSION__";
//--------------------------------------------------------------------------------------------
private MySession(){}
//--------------------------------------------------------------------------------------------
public static MySession Current
{
get
{
MySession session =
(MySession)HttpContext.Current.Session[_SessionName];
if (session == null)
{
session = new MySession();
session.Property1 = new Property1();
session.Property2 = new Property2();
session.UserName = "";
HttpContext.Current.Session[_SessionName] = session;
}
return session;
}
}
public string UserName { get; set; }
public Property1 Property1 { get; set; }
public Property2 Property2 { get; set; }
}
