C# 多语言网站：Azure部署与localhost不同的行为

编辑：完整代码可在中找到

我已经为多语言网站构建了一个ASP.NETMVC5多语言应用程序

在（2）中，它使用了一个“技巧”来解决“我希望完整的X.cshtml以语言Y呈现”问题：它添加了一个后缀ViewName.fr.cshtml，以便将视图自动重定向到正确的语言。这是代码，我认为这是代码中与我的问题相关的唯一部分：

public class LocalizedViewEngine : RazorViewEngine
{
    public override ViewEngineResult FindPartialView (ControllerContext controllerContext, string partialViewName, bool useCache)
    {
        List<string> searched = new List<string>();

        if (!string.IsNullOrEmpty(partialViewName))
        {
            ViewEngineResult result;

            result = base.FindPartialView(controllerContext, string.Format("{0}.{1}", partialViewName, CultureInfo.CurrentUICulture.Name), useCache);

            if (result.View != null)
            {
                return result;
            }

            searched.AddRange(result.SearchedLocations);

            result = base.FindPartialView(controllerContext, string.Format("{0}.{1}", partialViewName, CultureInfo.CurrentUICulture.TwoLetterISOLanguageName), useCache);

            if (result.View != null)
            {
                return result;
            }

            searched.AddRange(result.SearchedLocations);
        }

        return new ViewEngineResult(searched.Distinct().ToList());
    }

    public override ViewEngineResult FindView (ControllerContext controllerContext, string viewName, string masterName, bool useCache)
    {
        List<string> searched = new List<string>();

        if (!string.IsNullOrEmpty(viewName))
        {
            ViewEngineResult result;

            result = base.FindView(controllerContext, string.Format("{0}.{1}", viewName, CultureInfo.CurrentUICulture.Name), masterName, useCache);

            if (result.View != null)
            {
                return result;
            }

            searched.AddRange(result.SearchedLocations);

            result = base.FindView(controllerContext, string.Format("{0}.{1}", viewName, CultureInfo.CurrentUICulture.TwoLetterISOLanguageName), masterName, useCache);

            if (result.View != null)
            {
                return result;
            }

            searched.AddRange(result.SearchedLocations);
        }

        return new ViewEngineResult(searched.Distinct().ToList());
    }
}

我就是这样解决这个问题的：

    public ActionResult Index()
    {
        // The Index is the only page that does not respond to the LocalizedViewEngine as it should...
        var currentCulture = CultureInfo.CurrentUICulture.TwoLetterISOLanguageName;
        if (currentCulture != LocalizationAttribute.DefaultCulture)
            return View(string.Format("Index.{0}", currentCulture));
        else
            return View();
    }

这就是说：我强制了唯一一个没有被重新路由到

{View}.{Culture}.cshtml

的案例（操作索引），并强制在控制器中的操作中这样做。我不喜欢这个解决方案，但至少它是有效的。它只在这种非常特殊的情况下进行了本地化，这是由于Azure部署对索引的处理方式与我的localhost IIS有所不同

// (some captcha-specific routing)
routes.IgnoreRoute("{resource}.axd/{*pathInfo}");

// BotDetect requests must not be routed:
routes.IgnoreRoute("{*botdetect}",
  new { botdetect = @"(.*)BotDetectCaptcha\.ashx" });

// the language route:
routes.MapRoute(
    "Default",
    "{culture}/{controller}/{action}/{id}",
    new
    {
        culture = "ca",
        controller = "Home",//ControllerName
        action = "Index",//ActionName
        id = UrlParameter.Optional
    }
).RouteHandler = new LocalizedMvcRouteHandler();

    public ActionResult Index()
    {
        // The Index is the only page that does not respond to the LocalizedViewEngine as it should...
        var currentCulture = CultureInfo.CurrentUICulture.TwoLetterISOLanguageName;
        if (currentCulture != LocalizationAttribute.DefaultCulture)
            return View(string.Format("Index.{0}", currentCulture));
        else
            return View();
    }
