Our coding is given below.

using System;
using System.Collections.Generic;
using System.ComponentModel.DataAnnotations;
using System.Linq;
using System.Web;
namespace MultiLanMVC.Models
{
    public class Registration
    {
        [Display(Name = "FirstName", ResourceType = typeof(Resource))]
        [Required(ErrorMessageResourceType = typeof(Resource), ErrorMessageResourceName = "FirstNameRequired")]
        public string FirstName { get; set; }
        [Display(Name = "LastName", ResourceType = typeof(Resource))]
        [Required(ErrorMessageResourceType = typeof(Resource), ErrorMessageResourceName = "LastNameRequired")]
        public string LastName { get; set; }
        [Display(Name = "Email", ResourceType = typeof(Resource))]
        [Required(ErrorMessageResourceType = typeof(Resource), ErrorMessageResourceName = "EmailRequired")]
        [RegularExpression(@"^([0-9a-zA-Z]([\+\-_\.][0-9a-zA-Z]+)*)+@(([0-9a-zA-Z][-\w]*[0-9a-zA-Z]*\.)+[a-zA-Z0-9]{2,3})$", ErrorMessageResourceType = typeof(Resource), ErrorMessageResourceName = "EmailInvalid")]
        public string Email { get; set; }
        [Display(Name = "Country", ResourceType = typeof(Resource))]
        [Required(ErrorMessageResourceType = typeof(Resource), ErrorMessageResourceName = "CountryNameRequired")]
        public string Country { get; set; }
    }
}

Step 10. Go to Solution Explorer= > Right click on Project name= > Add= > Class => Enter Class name= > Add.

Language Mang

Coding

using System;
using System.Collections.Generic;
using System.Globalization;
using System.Linq;
using System.Threading;
using System.Web;
namespace MultiLanMVC
{
    public class LanguageMang
    {
        public static List<Languages> AvailableLanguages = new List<Languages>
        {
            new Languages { LanguageFullName = "English", LanguageCultureName = "en" },
            new Languages { LanguageFullName = "Hindi", LanguageCultureName = "Hi" },
            new Languages { LanguageFullName = "japanese", LanguageCultureName = "Ja" },
            new Languages { LanguageFullName = "arabic", LanguageCultureName = "Ar" },
        };
        public static bool IsLanguageAvailable(string lang)
        {
            return AvailableLanguages.Any(a => a.LanguageCultureName.Equals(lang));
        }
        public static string GetDefaultLanguage()
        {
            return AvailableLanguages[0].LanguageCultureName;
        }
        public void SetLanguage(string lang)
        {
            try
            {
                if (!IsLanguageAvailable(lang))
                    lang = GetDefaultLanguage();
                var cultureInfo = new CultureInfo(lang);
                Thread.CurrentThread.CurrentUICulture = cultureInfo;
                Thread.CurrentThread.CurrentCulture = CultureInfo.CreateSpecificCulture(cultureInfo.Name);
                HttpCookie langCookie = new HttpCookie("culture", lang);
                langCookie.Expires = DateTime.Now.AddYears(1);
                HttpContext.Current.Response.Cookies.Add(langCookie);
            }
            catch (Exception) { }
        }
    }
    public class Languages
    {
        public string LanguageFullName { get; set; }
        public string LanguageCultureName { get; set; }
    }
}

Step 11. Here, add another class. Go to Solution Explorer= > Right-click on Project name= > Add= > Class => Enter class name= > Add. Here, our Class name is “MyController”.

My controller

Our coding is given below.

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.Mvc;
namespace MultiLanMVC
{
    public class MyController : Controller
    {
        protected override IAsyncResult BeginExecuteCore(AsyncCallback callback, object state)
        {
            string lang = null;
            HttpCookie langCookie = Request.Cookies["culture"];

            if (langCookie != null)
            {
                lang = langCookie.Value;
            }
            else
            {
                var userLanguage = Request.UserLanguages;
                var userLang = userLanguage != null ? userLanguage[0] : "";
                if (userLang != "")
                {
                    lang = userLang;
                }
                else
                {
                    lang = LanguageMang.GetDefaultLanguage();
                }
            }
            new LanguageMang().SetLanguage(lang);
            return base.BeginExecuteCore(callback, state);
        }
    }
}

Step 12. Now, right-click on your Controller folder and add=>Controller=>Empty Controller and add Controller name. I have a controller named “HomeController”.

MVC five controller

Code

using MultiLanMVC.Models;
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.Mvc;
namespace MultiLanMVC.Controllers
{
    public class HomeController : MyController
    {
        // GET: Home
        public ActionResult Index()
        {
            return View();
        }
        [HttpPost]
        public ActionResult Index(Registration r)
        {
            return View(r);
        }
        public ActionResult ChangeLanguage(string lang)
        {
            new LanguageMang().SetLanguage(lang);
            return RedirectToAction("Index", "Home");
        }
    }
}

Step 13. Now, right-click on ActionResult and add a new View. Click to add button.

@model MultiLanMVC.Models.Registration
@{
    ViewBag.Title = MultiLanMVC.Resource.Register;
}
<h2>@MultiLanMVC.Resource.Register</h2>
@using (Html.BeginForm())
{
    @Html.AntiForgeryToken()
    <div class="form-horizontal">
        <h4>Registration</h4>
        <hr />
        @Html.ValidationSummary(true, "", new { @class = "text-danger" })
        <div class="form-group">
            @Html.LabelFor(model => model.FirstName, htmlAttributes: new { @class = "control-label col-md-2" })
            <div class="col-md-10">
                @Html.EditorFor(model => model.FirstName, new { htmlAttributes = new { @class = "form-control" } })
                @Html.ValidationMessageFor(model => model.FirstName, "", new { @class = "text-danger" })
            </div>
        </div>
        <div class="form-group">
            @Html.LabelFor(model => model.LastName, htmlAttributes: new { @class = "control-label col-md-2" })
            <div class="col-md-10">
                @Html.EditorFor(model => model.LastName, new { htmlAttributes = new { @class = "form-control" } })
                @Html.ValidationMessageFor(model => model.LastName, "", new { @class = "text-danger" })
            </div>
        </div>
        <div class="form-group">
            @Html.LabelFor(model => model.Email, htmlAttributes: new { @class = "control-label col-md-2" })
            <div class="col-md-10">
                @Html.EditorFor(model => model.Email, new { htmlAttributes = new { @class = "form-control" } })
                @Html.ValidationMessageFor(model => model.Email, "", new { @class = "text-danger" })
            </div>
        </div>
        <div class="form-group">
            @Html.LabelFor(model => model.Country, htmlAttributes: new { @class = "control-label col-md-2" })
            <div class="col-md-10">
                @Html.EditorFor(model => model.Country, new { htmlAttributes = new { @class = "form-control" } })
                @Html.ValidationMessageFor(model => model.Country, "", new { @class = "text-danger" })
            </div>
        </div>
        <div class="form-group">
            <div class="col-md-offset-2 col-md-10">
                <input type="submit" value="@MultiLanMVC.Resource.Register" class="btn btn-default" />
            </div>
        </div>
    </div>
}
<div>
    @Html.ActionLink("Back to List", "Index")
</div>
<script src="~/Scripts/jquery-1.10.2.min.js"></script>
<script src="~/Scripts/jquery.validate.min.js"></script>
<script src="~/Scripts/jquery.validate.unobtrusive.min.js"></script>

Step 14. Add the given code to the Complete Layout page. (_Layout .cshtml).

<div style="padding:5px">
    @{
        foreach (var i in MultiLanMVC.LanguageMang.AvailableLanguages)
        {
            @Html.ActionLink(i.LanguageFullName, "ChangeLanguage", "Home", new { lang = i.LanguageCultureName }, null)
            <text> </text>
        }
    }
</div>
