我对 MVC 中的文化变化很感兴趣。我尝试了两种方法，但显然我在某处错了。

在我的 Web.config 中我有:

 <globalization uiCulture="auto" culture="auto" />

这就是我试图改变线程文化的方式:

 <li>@Html.ActionLink("Eng", "ChangeCulture", "Home", new { lang="en-US"}, new { @class = "languageSelectorEnglish" })</li>

第一种方法

我有以下 Controller :

    public void ChangeCulture(string lang)
    {
        Thread.CurrentThread.CurrentCulture = CultureInfo.GetCultureInfo(lang);
        Thread.CurrentThread.CurrentUICulture = CultureInfo.GetCultureInfo(lang);

        Response.Cookies.Remove("Language");
        var langCookie = new HttpCookie("Language");
        langCookie["Language"] = lang;
        langCookie.Value = lang;
        langCookie.Expires = System.DateTime.Now.AddDays(21);
        Response.Cookies.Add(langCookie);

        Response.Redirect(Request.UrlReferrer.ToString());
    }

第二种方法

    public ActionResult ChangeCulture(string lang)
    {
        Thread.CurrentThread.CurrentCulture = CultureInfo.GetCultureInfo(lang);
        Thread.CurrentThread.CurrentUICulture = CultureInfo.GetCultureInfo(lang);

        // Split the url to url + query string
        var fullUrl= Request.UrlReferrer.ToString();
        var questionMarkIndex = fullUrl.IndexOf('?');
        string queryString = null;
        string url = fullUrl;
        if (questionMarkIndex != -1) // There is a QueryString
        {
            url = fullUrl.Substring(0, questionMarkIndex);
            queryString = fullUrl.Substring(questionMarkIndex + 1);
        }

        // Arranges
        var request = new HttpRequest(null, url, queryString);
        var response = new HttpResponse(new StringWriter());
        var httpContext = new HttpContext(request, response);

        var routeData = RouteTable.Routes.GetRouteData(new HttpContextWrapper(httpContext));

        // Extract the data    
        var values = routeData.Values;
        var controllerName = values["controller"];
        var actionName = values["action"];
        var areaName = values["area"];

        return RedirectToAction(actionName.ToString());
    }

我哪里错了？谢谢。

最佳答案

看来我需要为我的资源字符串而不是线程覆盖culture。所以我最后的方法是这样的:

    public void ChangeCulture(string lang)
    {
         Resources.Resources.Culture = new CultureInfo(lang);

         Response.Redirect(Request.UrlReferrer.ToString());
    }

希望这对您有所帮助。

更新:

当您的应用程序被多个用户使用时，上面的代码并不好，因为它为每个用户设置相同的文化，无论他们使用什么浏览器。

最好的方法是创建一个在浏览器中设置 cookie 的方法:

    public void ChangeCulture(string lang)
    {
        Response.Cookies.Remove("Language");

        HttpCookie languageCookie = System.Web.HttpContext.Current.Request.Cookies["Language"];

        if (languageCookie == null) languageCookie = new HttpCookie("Language");

        languageCookie.Value = lang;

        languageCookie.Expires = DateTime.Now.AddDays(10);

        Response.SetCookie(languageCookie);

        Response.Redirect(Request.UrlReferrer.ToString());
    }

在此之后(棘手的方法)，您需要让每个 Controller 都继承自一个 BaseController。这很棘手，因为您需要覆盖 Initialize。

protected override void Initialize(System.Web.Routing.RequestContext requestContext)
    {


        HttpCookie languageCookie = System.Web.HttpContext.Current.Request.Cookies["Language"];
        if (languageCookie != null)
        {
            Thread.CurrentThread.CurrentCulture = new CultureInfo(languageCookie.Value);
            Thread.CurrentThread.CurrentUICulture = new CultureInfo(languageCookie.Value);
        }
        else
        {
        //other code here
        }


        base.Initialize(requestContext);
    }
