how to apply the Session in asp.netMVC 4

It's not recommended to use Session in Web API for various of good reasons.
However, in case you're still so interested to access Session for any business
needs, here is a quick solution to allow accessing Session in Web API.

// In global.asax

public class MvcApp : System.Web.HttpApplication

{

public static void RegisterRoutes(RouteCollection routes)

{

var route = routes.MapHttpRoute(

name: "DefaultApi",

routeTemplate: "api/{controller}/{id}",

defaults: new { id = RouteParameter.Optional }

);

route.RouteHandler = new MyHttpControllerRouteHandler();

}

// Create two new classes

public class MyHttpControllerHandler : HttpControllerHandler, IRequiresSessionState

{

public MyHttpControllerHandler(RouteData routeData): base(routeData)

{

}

public class MyHttpControllerRouteHandler : HttpControllerRouteHandler

{

protected override IHttpHandler GetHttpHandler(RequestContext requestContext)

{

return new MyHttpControllerHandler(requestContext.RouteData);

}

// Now Session is visible in your Web API

public class ValuesController : ApiController

{

public string GET(string input)

{

var session = HttpContext.Current.Session;

if (session != null)

{

if (session["Time"] == null)

session["Time"] = DateTime.Now;

return "Session Time: " + session["Time"] + input;

}

return "Session is not availabe" + input;

}

If you want to pass data from one page to another. You have 3 options with you
1. ViewData
2. ViewBag
3. TempData
I think so TempData will solve your problem.
If not just let me know.

Thanks,
