Enabling session state in Web API

Create two classes; SessionControllerHandler and SessionHttpControllerRouteHandler. Implement as follows:

public class SessionControllerHandler : HttpControllerHandler, IRequiresSessionState

{

    public SessionControllerHandler(RouteData routeData)

        : base(routeData)

    { }

}

 

public class SessionHttpControllerRouteHandler : HttpControllerRouteHandler

{

    protected override IHttpHandler GetHttpHandler(RequestContext requestContext)

    {

        return new SessionControllerHandler(requestContext.RouteData);

    }

}







In your WebApiConfig, add the following above your route declaration(s):

public static class WebApiConfig { public static void Register(HttpConfiguration config) { // Web API configuration and services var httpControllerRouteHandler = typeof(HttpControllerRouteHandler).GetField("_instance", System.Reflection.BindingFlags.Static | System.Reflection.BindingFlags.NonPublic); if (httpControllerRouteHandler != null) { httpControllerRouteHandler.SetValue(null, new Lazy<HttpControllerRouteHandler>(() => new SessionHttpControllerRouteHandler(), true)); } // Web API routes config.MapHttpAttributeRoutes(); config.Routes.MapHttpRoute( name: "DefaultApi", routeTemplate: "api/{controller}/{id}", defaults: new { id = RouteParameter.Optional } ); } }

Now Session is On

HttpContext.Current.Session["ForLeftMenu"] = "Rajon";

if (HttpContext.Current.Session["ForLeftMenu"] != null)

{

  string text = HttpContext.Current.Session["ForLeftMenu"].ToString();

            }
