How to redirect user to action method of specific controller asp.net mvc

Question

i was reading a article on mvc for uncontrolled action http://www.codeproject.com/Articles/874284/ASP-NET-MVC-Performance-Tips?msg=5003414#xx5003414xx

they write this code for uncontrolled action

protected override void HandleUnknownAction(string actionName)
{
       RedirectToAction("Index").ExecuteResult(this.ControllerContext);
}

author is saying that if a user request http://localhost:58234/default/index1, index1 action which does not exist so it will redirect to the default/index

i want to develop a base controller and put a routine which detect action method or controller exist or not for request url. if not exist then it will redirect user to a action method of a specific controller with query string value. as a result we can show a friendly message to user.

still i got no chance to work with mvc in office. just out of curiosity i like to know how to achieve the functionality with base controller?

help me with sample code. thanks

You can simply create base class as follows

 public class BaseController : Controller
    {
        protected override void HandleUnknownAction(string actionName)
        {
            //Your code
            RedirectToAction("Index").ExecuteResult(this.ControllerContext);
        }
    }

And your all controller should inherit BaseController instead of Controller.

UseCase

YOURDOMAIN.COM\CorrectController\InCorrectActionMethod // `HandleUnknownAction` will be called

YOURDOMAIN.COM\InCorrectController\InCorrectActionMethod // `HandleUnknownAction` will be not be called, in this case 404 will be thrown.

How does HandleUnknownAction get invoked?

Mox Shah Over a year ago

So whenever if invalid action method is found then this HandleUnknownAction , will be invoked, in-case if controller name it self is not correct then this it will not be invoked.

SBirthare Over a year ago

Who tells MVC handler to invoke this method and not HandleUnknownAction123()?

Mox Shah Over a year ago

Method name it self describe its duty, Check this link msdn.microsoft.com/en-us/library/… this method will Called when a request matches this controller, but no method with the specified action name is found in the controller.

You are right, I didn't know about this method in Controller class. +1

Why you need to Do like So. Just do like this . Manage Application_Error event form Global.asax file .

protected void Application_Error(Object sender, EventArgs e)
    {

        //process 404 HTTP errors
        var httpException = exception as HttpException;
        if (httpException != null && httpException.GetHttpCode() == 404)
        {
                Response.Clear();
                Server.ClearError();
                Response.TrySkipIisCustomErrors = true;

                // Call target Controller and pass the routeData.
                IController errorController = "Your Controller";

                var routeData = new RouteData();
                routeData.Values.Add("controller", "Common");
                routeData.Values.Add("action", "PageNotFound");

                errorController.Execute(new RequestContext(new HttpContextWrapper(Context), routeData));

        }
    }

Hope this help .
