我需要将多语言链接更改为一个下拉框吗？ 我怎样才能做到这一点

Question

I need help. I'm trying to create a drop-down box with the text French and English as opposed to the two links that I have now in my view. I'm working in MVC and I need to have a drop-down box that should auto-submit based upon the user's language selection (not having the extra step of a submit button), but just post based upon selection. There's probably some way to do it with select tags and option tags and some javascript but I'm just not sure how. Does anyone know how to do this?

Here is my controller

using System;
using System.Collections.Generic;
using System.Globalization;
using System.Linq;
using System.Threading;
using System.Web;
using System.Web.Mvc;

 namespace MultiLanguage.Controllers
{
public class LanguageController : Controller
{
    // GET: Language
    public ActionResult Index()
    {
        return View();
    }

    public ActionResult Change(String LanguageAbbrevation)
    {
        if(LanguageAbbrevation !=null)
        {
            Thread.CurrentThread.CurrentCulture = CultureInfo.CreateSpecificCulture(LanguageAbbrevation);
            Thread.CurrentThread.CurrentUICulture = new CultureInfo(LanguageAbbrevation);
        }
        HttpCookie cookie = new HttpCookie("Language");
        cookie.Value = LanguageAbbrevation;
        Response.Cookies.Add(cookie);

        return View("Index");
    }
}

}

Here is my View

@{
ViewBag.Title = "Index";
Layout = "~/Views/Shared/_Layout.cshtml";
}

<ul>
<li>@Html.ActionLink("English","Change","Language",new {LanguageAbbrevation = "en"}, null)</li>
<li>@Html.ActionLink("French", "Change", "Language", new { LanguageAbbrevation = "fr" }, null)</li>
<li>@DateTime.Now.ToString()</li>
</ul>

1. In Controller

public ActionResult Change(string languageAbbrevation)
        {
            if (languageAbbrevation != null)
            {
                Thread.CurrentThread.CurrentCulture = new CultureInfo(languageAbbrevation);
                Thread.CurrentThread.CurrentCulture = CultureInfo.CreateSpecificCulture(languageAbbrevation);

            }

            HttpCookie cookie = new HttpCookie("Language");
            cookie.Value = languageAbbrevation;
            Response.Cookies.Add(cookie);
            Response.Redirect("Index");
            return View("Index");
        }

2.In Global

protected void Application_BeginRequest(object sender, EventArgs e)
        {
            HttpCookie cookie = HttpContext.Current.Request.Cookies["Language"];
            if (cookie != null && cookie.Value != null)
            {
                System.Threading.Thread.CurrentThread.CurrentCulture = new System.Globalization.CultureInfo(cookie.Value);
                System.Threading.Thread.CurrentThread.CurrentUICulture = new System.Globalization.CultureInfo(cookie.Value);
            }
            else
            {
                System.Threading.Thread.CurrentThread.CurrentCulture = new System.Globalization.CultureInfo("pt");
                System.Threading.Thread.CurrentThread.CurrentUICulture = new System.Globalization.CultureInfo("pt");
            }
        }

3.In html

  <div class="dropdown pull-right"> <button class="btn btn-link dropdown-toggle" type="button" data-toggle="dropdown"> @Html.Label(Project.Resources.HomeTexts.Language) <span class="caret"></span> </button> <ul class="dropdown-menu"> <li>@Html.ActionLink("English", "Change", new { languageAbbrevation = "en" }, null)</li> <li>@Html.ActionLink("Portugues", "Change", new { languageAbbrevation = "pt" }, null)</li> </ul> </div> 

4.create resource files HomeTexts.en.resx HomeTexts.resx -pt default

5.then use labels @Html.Label(Project.Resources.HomeTexts.Login)
