[Visual Basic]
Public ReadOnly Property Session As HttpSessionState
[C#]
public HttpSessionState Session {get;}
[C++]
public: __property HttpSessionState* get_Session();
[JScript]
public function get Session() : HttpSessionState;

Property Value

A System.Web.HttpSessionState representing the ASP.NET session state object for the current session.

Example

[Visual Basic, C#] The example below uses session state to determine how many times a particular session accesses the XML Web service method SessionHitCounter. In this example, the EnableSession property of the WebMethodAttribute is set to true in order to gain access to session state.

[Visual Basic] 
<%@ WebService Language="VB" Class="Util" %>
 
Imports System.Web.Services

Public Class Util
    Inherits WebService
    
    <WebMethod(Description := "Per session Hit Counter", _
        EnableSession := True)> _
    Public Function SessionHitCounter() As Integer
        
        If Session("HitCounter") Is Nothing Then
            Session("HitCounter") = 1
        Else
            Session("HitCounter") = CInt(Session("HitCounter")) + 1
        End If
        Return CInt(Session("HitCounter"))
    End Function
End Class


[C#] 
<%@ WebService Language="C#" Class="Util" %>
 
 using System.Web.Services;
 
 public class Util: WebService {
   [ WebMethod(Description="Per session Hit Counter",EnableSession=true)]
    public int SessionHitCounter() {
       if (Session["HitCounter"] == null) {
          Session["HitCounter"] = 1;
       }
       else {
          Session["HitCounter"] = ((int) Session["HitCounter"]) + 1;
          }
       return ((int) Session["HitCounter"]);
    }   
 }
