解决方法@H_403_22@

我为此使用了一个全局ActionFilter，但最近我意识到，在OnActionExecuting方法中设置当前文化在某些情况下太晚了。例如，当POST请求后的模型到达控制器时，ASP.NET MVC为模型创建元数据。它发生在任何动作被执行之前。因此，DisplayName属性值和其他数据注释东西在这一点使用默认文化处理。

最后，我将设置当前文化移动到自定义IControllerActivator实现，它的工作方式像一个魅力。我想从请求生命周期的角度来看，在自定义控制器工厂中托管这个逻辑几乎是一样的，就像你今天一样。它比使用全局ActionFilter更可靠。

CultureAwareControllerActivator.cs：

public class CultureAwareControllerActivator: IControllerActivator
{
    public IController Create(RequestContext requestContext,Type controllerType)
    {
        //Get the {language} parameter in the RouteData
        string language = requestContext.RouteData.Values["language"] == null ?
            "tr" : requestContext.RouteData.Values["language"].ToString();
 
        //Get the culture info of the language code
        CultureInfo culture = CultureInfo.GetCultureInfo(language);
        Thread.CurrentThread.CurrentCulture = culture;
        Thread.CurrentThread.CurrentUICulture = culture;
 
        return DependencyResolver.Current.GetService(controllerType) as IController;
    }
}

Global.asax.cs：

public class MvcApplication : System.Web.HttpApplication
{
    protected void Application_Start()
    {
        ...
        ControllerBuilder.Current.SetControllerFactory(new DefaultControllerFactory(new CultureAwareControllerActivator()));
    }
}
