MVC 多语言

最近项目需要用到多语言。

研究了一下，也参考了很多技术文章。

这里贴一下参考地址：http://www.cnblogs.com/unintersky/p/3969612.html

主要步骤我这里简述一下：

一：   MVC项目中 新增  Lang文件夹

文件夹中添加 CultureAwareHttpModule.cs类

具体代码：

public class CultureAwareHttpModule : IHttpModule
    {
        private CultureInfo currentCulture;
        private CultureInfo currentUICulture;

        public void Dispose()
        {//throw new NotImplementedException();
        }

        public void Init(HttpApplication context)
        {
            //throw new NotImplementedException();
            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 == 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;
        }
    }

继续添加

增加3个资源文件：

Language.resx 默认语言

Language.zh-cn.resx 中文

Language.en-us.resx 英文

二：修改 路由配置

public class RouteConfig
    {
        public static void RegisterRoutes(RouteCollection routes)
        {
            routes.IgnoreRoute("{resource}.axd/{*pathInfo}");
            routes.MapRoute(
              "Globalization",
              "{lang}/{controller}/{action}/{id}",
              new { lang = "zh", controller = "Login", action = "Login", 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 = "Test", action = "Index", id = UrlParameter.Optional }
            //);
        }
    }

三：  修改web.config配置文件

命名空间别打错了。

<system.webServer>
    <modules>
      <add name="CultureAwareHttpModule" type="TestMVC.Lang.CultureAwareHttpModule" />
    </modules>
</system.webServer>

然后我们创建一个 view

代码如下：

@using TestMVC.Lang
@{
    ViewBag.Title = "Test";
}

<div>
@{
                string controller = ViewContext.Controller.ValueProvider.GetValue("controller").RawValue.ToString();
                string action = ViewContext.Controller.ValueProvider.GetValue("action").RawValue.ToString();
                
                System.Globalization.CultureInfo info = System.Threading.Thread.CurrentThread.CurrentCulture;
            }

            @Html.ActionLink("中文", action, new { Controller = controller, lang = "zh-CN" }, new { @class = "disib", @id = "aCN" })
            @Html.ActionLink("English", action, new { Controller = controller, lang = "en-US" }, new { @class = "disib", @id = "aUS" })

    <div style="color:red;">
    @Language.Test
        </div>
</div>

效果如下：
