我希望在两种语言(PL和EN)之间切换MVC 3中的视图。我在Views-EN和PL中创建了两个文件夹。因此,在任何网站点击相应的语言链接后,我希望我的路线更改为:
routes.MapRoute(
"pl", // Route name
"{controller}/{action}/{id}", // URL with parameters
new { controller = "PL", action = "Index", id = UrlParameter.Optional } // Parameter defaults
);
为:
routes.MapRoute(
"en", // Route name
"{controller}/{action}/{id}", // URL with parameters
new { controller = "EN", action = "Index", id = UrlParameter.Optional } // Parameter defaults
);
当我点击相应的链接(语言切换器)时,它会更改对所有线程持久的CultureInfo。 _Layout View with switcher:
<ul>
<li>@Html.ActionLink("En", "ChangeCulture", null, new { lang = "en"}, null)</li>
<li>@Html.ActionLink("Pl", "ChangeCulture", null, new { lang = "pl"}, null)</li>
</ul>
和controller(它还设置了静态变量lang,可以在每个控制器的方法中看到并在请求之间保持不变):
public ActionResult ChangeCulture(string lang)
{
PLController.lang = lang;
CultureSettings setCulture = new CultureSettings();
setCulture.InitializeCulture(lang);
cookie.Value = CultureInfo.CurrentCulture.Name;
this.ControllerContext.HttpContext.Response.Cookies.Add(cookie);
return View("Index");
}
InitializeCulture方法从Page类重写,如下所示:
public class CultureSettings : Page{
public void InitializeCulture(string culture)
{
String selectedLanguage;
if(culture == null)
{
selectedLanguage = "pl";
}
else
{
selectedLanguage = culture;
}
UICulture = selectedLanguage;
Culture = selectedLanguage;
Thread.CurrentThread.CurrentCulture =
CultureInfo.CreateSpecificCulture(selectedLanguage);
Thread.CurrentThread.CurrentUICulture = new
CultureInfo(selectedLanguage);
base.InitializeCulture();
}
}
正确设置CultureInfo。现在我想(根据当前的CultureInfo)切换每个导航链接的路线并将路线模式从mysite.com/PL/ {controller} / {action}更改为mysite.com/EN/{controller}/{action}.
有没有人对此问题有任何想法或更好的方法?但条件是地址必须看起来像这样的mysite.com/EN或mysite.com/PL - 没有区别(即en.mysite.com)

您必须决定的第一件事是存储当前用户语言的位置。有不同的可能性:
恕我直言,出于搜索引擎优化的目的,最好将它作为网址的一部分。
所以我建议编写一个自定义路由,它将解析网址中的语言并设置当前的线程文化:
public class LocalizedRoute : Route
{
public LocalizedRoute()
: base(
"{lang}/{controller}/{action}/{id}",
new RouteValueDictionary(new
{
lang = "en-US",
controller = "home",
action = "index",
id = UrlParameter.Optional
}),
new RouteValueDictionary(new
{
lang = @"[a-z]{2}-[a-z]{2}"
}),
new MvcRouteHandler()
)
{
}
public override RouteData GetRouteData(HttpContextBase httpContext)
{
var rd = base.GetRouteData(httpContext);
if (rd == null)
{
return null;
}
var lang = rd.Values["lang"] as string;
if (string.IsNullOrEmpty(lang))
{
// pick a default culture
lang = "en-US";
}
var culture = new CultureInfo(lang);
Thread.CurrentThread.CurrentCulture = culture;
Thread.CurrentThread.CurrentUICulture = culture;
return rd;
}
}
我们现在可以在Global.asax
注册此自定义路线:
public static void RegisterRoutes(RouteCollection routes)
{
routes.IgnoreRoute("{resource}.axd/{*pathInfo}");
routes.Add("Default", new LocalizedRoute());
}
好的,现在让我们有一个模型:
public class MyViewModel
{
[DisplayFormat(DataFormatString = "{0:d}")]
public DateTime Date { get; set; }
}
控制器:
public class HomeController : Controller
{
public ActionResult Index()
{
return View(new MyViewModel
{
Date = DateTime.Now
});
}
public ActionResult Test()
{
return Content(DateTime.Now.ToLongDateString());
}
}
观点:
@model MyViewModel
@Html.DisplayFor(x => x.Date)
<ul>
<li>@Html.ActionLink("switch to fr-FR", "index", new { lang = "fr-FR" })</li>
<li>@Html.ActionLink("switch to de-DE", "index", new { lang = "de-DE" })</li>
<li>@Html.ActionLink("switch to en-US", "index", new { lang = "en-US" })</li>
</ul>
@Html.ActionLink("Test culture", "test")
现在,当您点击链接时,我们正在更改语言,此语言现在是路线的一部分。请注意,一旦您选择了该语言,该语言将保留在test
链接的路由中。
Scott Hanselman还在ASP.NET中写了一篇关于本地化和全球化的nice blog post,值得一试。

此解决方案无法解决此问题:
english: /en/home
french: /fr/accueil
english: /en/contactus
french: /fr/contacteznous
它只会做
/en/home
/fr/home
您还应该在字典中本地化路线并进行查找。
