我对MVC中的文化变迁有好奇心.我尝试了两种方式,但显然我在某个地方错了.
在我的Web.config我有：
<globalization uiCulture="auto" culture="auto" />
这是我如何改变线程文化：
<li>@Html.ActionLink("Eng","ChangeCulture","Home",new { lang="en-US"},new { @class = "languageSelectorEnglish" })</li>
第一种方法
我有以下控制器：
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());
}
我在哪里错了？谢谢.
解决方法
看来我需要覆盖我的资源字符串而不是线程的文化.所以我的最终方法是这样的：
public void ChangeCulture(string lang)
{
Resources.Resources.Culture = new CultureInfo(lang);
Response.Redirect(Request.UrlReferrer.ToString());
}
希望这可以帮助.
更新：
当您的应用程序被多个用户使用时,上面的代码不是很好,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.
这样做的好方法是在浏览器中设置一个cookie：
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());
}
之后(棘手的方法),您需要使每个控制器从一个BaseController继承.这是棘手的,因为你需要重写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);
}
