EnableSession Property of WebMethod in Web Service

EnableSession: It is used to enable session state for web method by simply set this property to true. We can enable session state for every individual method.
Now create a web service using EnableSession property of web method attribute. Take a Web Service Application and replace the code with following code.

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.Services;

namespace webmethodproperties
{
/// <summary>
/// Summary description for Service1
/// </summary>
[WebService(Namespace = "http://tempuri.org/")]
[WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)]
[System.ComponentModel.ToolboxItem(false)]
// To allow this Web Service to be called from script, using ASP.NET AJAX, uncomment the following line.
// [System.Web.Script.Services.ScriptService]
public class Service1 : System.Web.Services.WebService
{
[WebMethod(EnableSession=true )]
public int get()
{
if (Session["ss"] == null)
{
Session["ss"] = 1;
}
else
{
int i = (int)Session["ss"];
i++;
Session["ss"] = i;
}
return (int)Session["ss"];
}
}
}

This service will return a number that how many times the method has called. Then, Run the service application -> go to test page of service->invoke the method.

Output:



You will note that whenever you refresh the page, the number is increased by 1.
