How to access Session variable Inside Static methods / web service / web method

 We can access session using System.Web.SessionState.HttpSessionState   class.

By default, ASP.NET session support for each Web method is turned off. we have to explicitly

enable session support for each Web method that wants to use session state.

This is done by adding the EnableSession property to the WebMethod attribute of your

function.

VB.NET Code:

***********************************************************

VB.NET Code:

<WebMethod(EnableSession:=True)> _     Public Function SetSessionVar() As Integer         Dim cnt As Integer         If HttpContext.Current.Session("mysession") Is Nothing Then             cnt = 1         Else             cnt = convert.ToInt16(HttpContext.Current.Session("mysession")) + 1         End If         Context.Session("mysession") = cnt         Return cnt     End Function

C# Code :

[WebMethod(EnableSession = true)]     public static int SetSessionVar()     {         int cnt;         if(HttpContext.Current.Session("mysession") = null )         { cnt = 1 ;         }         else         { cnt = Convert.ToInt16(HttpContext.Current.Session("mysession")) + 1 ;         }         HttpContext.Current.Session("mysession") = cnt ;         return  cnt;     }

Solution : Access session variable in ASP.Net App_Code

If you want to get or set session inside App_Code class file then you must use .

To Set Value to Session variable

HttpContext.Current.Session("mysession") = "Tarun"

To Get Value to Session variable

Myvariable = HttpContext.Current.Session("mysession")

Get session variable in j query / JavaScript 

var mysessionItem = '<% Session("mysession") %>'
