public virtual HttpSessionState Session { get; }

Property Value

Type: System.Web.SessionState.HttpSessionState

The current session-state data.

Exception Condition

Occurs when the session information is set to null.

This property provides information about the current request's session. A Session object is maintained for each user that requests a page or document from an ASP.NET application. Variables stored in the Session object are not discarded when the user moves from page to page in the application; instead, these variables persist as long as the user is accessing pages in your application. For more information about session state, see ASP.NET Session State Overview.

The following code example creates a GetStyle function that retrieves a key stored in the session state of the Web Forms page and converts its value to a string.

// Create a private function that obtains
// information stored in Session state
// in the application's Global.asax file.
// When this method is called and a key name
// that is stored in Session state is passed
// as the paramter, the key is obtained and
// converted to a string.
String GetStyle(String key) {
  return Session[key].ToString();
