Override action method using plugin into nopCommerce3.8

This article learn you how to override the action method in nopcommerce 3.8 version. In this article i am going to overrride the contact us form to extend its funcationliy. but this action method override way is not worked over seo url(route value) like product url,category url etc.

Now i am going to show how to override the contact us page using plugin. This contact us form having only field like name,emailid,content but i want to add one more field that is contact no that help me to get contact detail of person who going to post this form.

For this feature i am going to add one project into plugin folder and add the ContactusController.cs, RouteProvider.cs,ContactUsModel.cs, ContactUs.cshtml, app.config,description.txt,OverrideActionMethodProvider.cs, packages.config, web.config. for now i have refer the Nop.Plugin.ExternalAuth.Facebook plugin.

My plugin structure is as describe with this article.

I have created
ContactSscontroller.cs => for contact us form get or post method.
RouteProvider.cs => used to over ride the route url of contact us. if user call the contact us url then our plugin form will be display instead of default nopcommerce form(action method).
ContactUsmodel.cs => to add one more property of contact no.
ContactUs.cshtml => This view file to display content of contact us form
OverrideActionMethodProvider.cs => having method of install and uninstall process for plugin.

ContactUsmodel.cs model file. I have added my new property into this model. I have used the existing ContactUsModel of nopcommerce.
using Nop.Web.Framework;

namespace Nop.Plugin.OverrideActionMethod.Models  
{  
    public class ContactUsModel : Nop.Web.Models.Common.ContactUsModel  
    {  
        [NopResourceDisplayName("Account.Fields.Phone")]          
        public string PhoneNo { get; set; }  
    }  
}

RouteProvider.cs routeProvider file override the existing route value

using Nop.Web.Framework.Localization;  
using Nop.Web.Framework.Mvc.Routes;  
using System.Web.Routing;  
using System.Linq;  

namespace Nop.Web.Infrastructure  
{  
    public partial class RouteProvider : IRouteProvider  
    {  
        public void RegisterRoutes(RouteCollection routes)  
        {  
            routes.Remove(routes.FirstOrDefault(c => (c as Route).Url == "contactus"));  
            routes.MapLocalizedRoute("ContactUs",  
                             "contactus",  
                             new { controller = "ContactUs", action = "ContactUs" },  
                             new[] { "Nop.Plugin.OverrideActionMethod.Controllers" });  
        }    
    }  
}

I have remove the existing route value of contact us and add my contact us route value. I have mention my controller name, action methon name and namespace for this.
