扩展ASP.NETMVC的ViewEngine支持本地化

我Äôve一直使用（准确的移动浏览器检测）构建ASP.NET MVC站点输出漂亮的移动友好的模板。斯科特谈到在他的岗位的技术一直非常好。
最近，当我不得不解决类似的问题时，试图呈现出本地化的模板，我到了斯科特从深层次看，AOS的方法，如果我能，Äòtweak？？它做我想要的东西，这，看上去就像在Visual Studio:

这让我的网站，为多国语言相同的URL。例如，/首页/指数的URL使用相同的控制器，模型等，但将呼吁为基于当前的UICulture英语和西班牙语的用户有不同的看法。


在这里，AOS如何我做到了。我了斯科特，AOS类和重构他们只是有点让我这个功能扩展，有weren，AOT得到重复的代码位（见{A4}）。
首先，我把现有的CustomMobileViewEngine类，并更名为它CustomViewEngine这台发动机将不再仅是移动。除thatm其他没有变化是必要的。

public class CustomViewEngine : IViewEngine



{

    public IViewEngine BaseViewEngine { get; private set; }

    public Func<ControllerContext, bool> IsTheRightDevice { get; private set; }

    public string PathToSearch { get; private set; }



    public CustomViewEngine(Func<ControllerContext, bool> isTheRightDevice, 

           string pathToSearch, IViewEngine baseViewEngine)

    {

        BaseViewEngine = baseViewEngine;

        IsTheRightDevice = isTheRightDevice;

        PathToSearch = pathToSearch;

    }



    public ViewEngineResult FindPartialView(ControllerContext context, 

           string viewName, bool useCache)

    {

        if (IsTheRightDevice(context))

        {

            return BaseViewEngine.FindPartialView(context, PathToSearch + 

                   "/" + viewName, useCache);

        }

        return new ViewEngineResult(new string[] { });

        //we found nothing and we pretend we looked nowhere

    }



    public ViewEngineResult FindView(ControllerContext context, 

                            string viewName, string masterName, bool useCache)

    {

        if (IsTheRightDevice(context))

        {

            return BaseViewEngine.FindView(context, PathToSearch + 

                   "/" + viewName, masterName, useCache);

        }

        return new ViewEngineResult(new string[] { });

        //we found nothing and we pretend we looked nowhere

    }



    public void ReleaseView(ControllerContext controllerContext, IView view)

    {

        throw new NotImplementedException();

    }

}

public static class LocalizationHelpers

{

    public static bool UICultureEquals(this ControllerContext c, string stringToFind)

    {

        var culture = CultureInfo.CurrentUICulture;

        var cultureName = culture != null ? culture.Name : string.Empty;



        return (cultureName.IndexOf(stringToFind, 

                StringComparison.OrdinalIgnoreCase) >= 0);

    }



    public static void AddLanguage<T>(this ViewEngineCollection ves, 

           string cultureName, string pathToSearch)

           where T : IViewEngine, new()

    {

        ves.AddCustomView<T>(c => c.UICultureEquals(cultureName), pathToSearch);

    }



    public static void AddLanguage<T>(this ViewEngineCollection ves, string cultureName)

        where T : IViewEngine, new()

    {

        ves.AddCustomView<T>(c => c.UICultureEquals(cultureName), cultureName);

    }

}

ViewEngines.Engines.Clear();

ViewEngines.Engines.AddLanguage<WebFormViewEngine>("es-ES");

ViewEngines.Engines.AddGenericMobile<WebFormViewEngine>();

ViewEngines.Engines.AddCustomView<WebFormViewEngine>(c => c.IsMobileDevice() 

    && c.UICultureEquals("es-ES"), "Mobile/es-ES");

ViewEngines.Engines.Add(new WebFormViewEngine());
