Ignore Route In MVC

Ignore Route in MVC
While working on one of my recent projects, we had several controllers and in one of the controllers we found a big issue. We needed to solve the issue in a production environment; until then, we needed to ignore the request and response process until the issue was fixed. 

Scenario:
We have two controllers in our project, Student and Employee, and we have some issue with the Employee controller. Until the issue is solved, we need to stop the user accessing the Employee controller using the RegisterRoutes method in Routeconfg.cs, 

By adding
routes.IgnoreRoute("Employee/");

Create an MVC Project 

Select Empty Template and Add MVC folder reference,

 

Add New Controller in Controller folder,



Add Student Controller,

 

Student Controller


Controller Code

1. using System;  
2. using System.Collections.Generic;  
3. using System.Linq;  
4. using System.Web;  
5. using System.Web.Mvc;  
6.   
7. namespace IngoreRoute.Controllers   
8. {  
9.     public class StudentController: Controller   
10.     {  
11.         // GET: Student  
12.         public ActionResult Index()   
13.         {  
14.             return View();  
15.         }  
16.     }  
17. }  

Add View For Index Action





Index View Code

1. @ {  
2.     ViewBag.Title = "Index";  
3. }  
4.   
5. < h2 > Student Controller - Index Action Method Get Invoked < /h2>  

Employee Controller

Followthe above process for how we added the Student Controller, just as we did the Employee Controller.

Run the Application
Before running the Application we need to set a startup controller as Student Controller and Index action in the Routeconfg.cs file.

1. routes.MapRoute  
2. (  
3.     name: "Default",  
4.     url: "{controller}/{action}/{id}",  
5.     defaults: new   
6.     {  
7.         controller = "Student", action = "Index", id = UrlParameter.Optional  
8.     }  
9. );  

Run the Application



Change the Url to Employee Controller.



In above image, the Employee controller is invoked successfully, but our scenario does not want to access Employee controller. In this situation we need to change the routeconfig.cs file.

1. using System;  
2. using System.Collections.Generic;  
3. using System.Linq;  
4. using System.Web;  
5. using System.Web.Mvc;  
6. using System.Web.Routing;  
7.   
8. namespace IngoreRoute  
9. {  
10.     public class RouteConfig  
11.     {  
12.         public static void RegisterRoutes(RouteCollection routes)  
13.       {  
14.             routes.IgnoreRoute("{resource}.axd/{*pathInfo}");  
15.   
16.             routes.IgnoreRoute("Employee/");  
17.   
18.             routes.MapRoute(  
19.                 name: "Default",  
20.                 url: "{controller}/{action}/{id}",  
21.                 defaults: new   
22.                 {  
23.                     controller = "Student", action = "Index", id = UrlParameter.Optional  
24.                 }  
25.             );  
26.         }  
27.     }  
28. }  

Add routes.IgnoreRoute("Employee/");



Run the Application and try to navigate to Employee Controller. Here's the output,



When we try to use Employee Controller, we get 404 error.
