由于项目页面较多,逐个Action去读取资源文件不大现实.就想到了使用 IHttpModule配合MVC的路由规则来实现.

首先创建以个mvc4的应用程序,
添加资源文件夹(自定义)Lang ,
然后在此文件夹下添加Home.Index.resx文件,
资源的访问修饰符用public
再添加Home.Index.en-us.resx文件
添加个字符串TEST
再添加Home.Index.zh-cn.resx文件
添加个字符串TEST

在home/index的视图中添加如下代码:
@MVC4多语言IHttpModule实现.Lang命名空间

Home_Index生成的类名

TEST要国际化的字段

注意: 只有Home.Index.resx会生成一个叫Home_Index的类,其他无类

然后添加以个实现了IHttpModule的类,暂且命名为MyModule
此类需要实现2个方法
public void Dispose() { } 即可
public void Init(HttpApplication context)方法

MyModule类的具体实现:

using System;using System.Collections.Generic;using System.Globalization;using System.Linq;using System.Threading;using System.Web;using System.Web.Routing; namespace MVC4多语言IHttpModule实现.Lang{    public class MyModule:IHttpModule    {        private CultureInfo currentCulture;        private CultureInfo currentUICulture;         public void Dispose() { }        public void Init(HttpApplication context)        {            context.BeginRequest += SetCurrentCulture;            context.EndRequest += RecoverCulture;        }        private void SetCurrentCulture(object sender, EventArgs args)        {            currentCulture = Thread.CurrentThread.CurrentCulture;            currentUICulture = Thread.CurrentThread.CurrentUICulture;            HttpContextBase contextWrapper = new HttpContextWrapper(HttpContext.Current);            RouteData routeData = RouteTable.Routes.GetRouteData(contextWrapper);            if (routeData =http://www.mamicode.com/= null)            {                return;            }            object culture;            if (routeData.Values.TryGetValue("lang", out culture))            {                try                {                    Thread.CurrentThread.CurrentCulture = new CultureInfo(culture.ToString());                    Thread.CurrentThread.CurrentUICulture = new CultureInfo(culture.ToString());                }                catch                { }            }        }        private void RecoverCulture(object sender, EventArgs args)        {            Thread.CurrentThread.CurrentCulture = currentCulture;            Thread.CurrentThread.CurrentUICulture = currentUICulture;        }    }}

然后添加路由规则:

using System;using System.Collections.Generic;using System.Linq;using System.Web;using System.Web.Http;using System.Web.Mvc;using System.Web.Optimization;using System.Web.Routing; namespace MVC4多语言IHttpModule实现{    // 注意: 如需啟用 IIS6 或 IIS7 傳統模式的說明，    // 請造訪 http://go.microsoft.com/?LinkId=9394801     public class MvcApplication : System.Web.HttpApplication    {        protected void Application_Start()        {            AreaRegistration.RegisterAllAreas();             WebApiConfig.Register(GlobalConfiguration.Configuration);            FilterConfig.RegisterGlobalFilters(GlobalFilters.Filters);            RouteConfig.RegisterRoutes(RouteTable.Routes);//在此方法中添加路由规则            BundleConfig.RegisterBundles(BundleTable.Bundles);            AuthConfig.RegisterAuth();        }    }}

View Code

RouteConfig.RegisterRoutes(RouteTable.Routes);//在此方法中添加路由规则

using System;using System.Collections.Generic;using System.Linq;using System.Web;using System.Web.Mvc;using System.Web.Routing; namespace MVC4多语言IHttpModule实现{    public class RouteConfig    {        public static void RegisterRoutes(RouteCollection routes)        {            routes.IgnoreRoute("{resource}.axd/{*pathInfo}");            routes.MapRoute(               "Globalization", // 路由名称               "{lang}/{controller}/{action}/{id}", // 带有参数的 URL               new { lang = "zh", controller = "Home", action = "Index", id = UrlParameter.Optional }, // 参数默认值               new { lang = "^[a-zA-Z]{2}(-[a-zA-Z]{2})?$" }    //参数约束           );            routes.MapRoute(                name: "Default",                url: "{controller}/{action}/{id}",                defaults: new { controller = "Home", action = "Index", id = UrlParameter.Optional }            );        }    }}

然后在配置文件中声明:
在web.config下的system.web下

<configuration>
    <system.web>
        <httpModules>
            <add name="MyModule" type="MyModule"/>
        </httpModules>
    </system.web>
</configuration>
事践显示这种声明注册方法在IIS7.0下，即win7下是不work的。
必须按如下声明：
<configuration>
    <system.webServer>
        <modules>
            <add name="MyModule" type="MyModule"/>
        </modules>
    </system.webServer>
</configuration>
