I want to check first the session as this action

Question

I have an simple MVC app I want to check first the session as this action

public ActionResult Index()
{
    if (Session["UserInfo"] == null)
    {
      return  RedirectToAction("Login", "Users");
    }
    return View();
}

My question is about is there a way to enforce this check to all actions without do it manual for each action?

Amit Mohanty · Answer

Yes, you can enforce this check for all actions in your MVC application without manually adding the session check to each action by using a custom action filter. Action filters are attributes that can be applied globally to controllers or actions, allowing you to perform common tasks like session checks in a centralized manner. Create a new class for your custom action filter attribute. Let's call it SessionCheckAttribute. using System; using System.Web.Mvc; public class SessionCheckAttribute : ActionFilterAttribute { public override void OnActionExecuting(ActionExecutingContext filterContext) { var session = filterContext.HttpContext.Session; if (session["UserInfo"] == null) { filterContext.Result = new RedirectResult("~/Home/Login"); } base.OnActionExecuting(filterContext); } } Apply the custom attribute to your controller or actions where you want the session check to be enforced: [SessionCheck] // Apply the custom attribute at the controller level public class HomeController : Controller { public ActionResult Index() { return View(); } public ActionResult AnotherAction() { return View(); } } //OR public class HomeController : Controller { [SessionCheck] // Apply the custom attribute at the action level public ActionResult Index() { return View(); } public ActionResult AnotherAction() { return View(); } }
