SessionStateItemCollection Class

The SessionStateItemCollection class is used to manage session-state variable values indexed by a variable name or by numerical index. The session-state variables are exposed to ASP.NET application code using the HttpSessionState class, which is accessed using the Session property of the current HttpContext or the Page. The HttpSessionState class calls the HttpSessionStateContainer class, which manages session-state variable values using the SessionStateItemCollection.

When you create a custom session-state provider based on the SessionStateStoreProviderBase class, use the SessionStateItemCollection class to manage the items stored in session state. If you need to create a custom object to manage session-state items, implement the ISessionStateItemCollection interface.

The following code example creates a new SessionStateItemCollection object and sets and gets values in the collection by name.

SessionStateItemCollection items = new SessionStateItemCollection();

items["LastName"] = "Wilson";
items["FirstName"] = "Dan";

foreach (string s in items.Keys)
  Response.Write("items[\"" + s + "\"] = " + items[s].ToString() + "<br />");
