需求:有些网站需要多语言显示，比如简体中文，繁体中文，英文。
1、创建一个mvc项目：
2、创建App_GlobalResources
创建了中文、英文两个语言的资源文件，中文是程序的默认语言，所以我先创建Global.resx文件，然后是Global.en.resx，中间的“en”是英语的Culture Name。如果你需要法语，那么你只需要再创建Global.fr.resx文件，Visual Studio会自动生成对应的类。
3、创建一个过滤器：
using System; using System.Collections.Generic; using System.Globalization; using System.Linq; using System.Threading; using System.Web; using System.Web.Mvc; namespace MultiMVCWebApp.Filters { public class LocalizationAttribute : ActionFilterAttribute { public override void OnActionExecuting(ActionExecutingContext filterContext) { if (filterContext.RouteData.Values["lang"] != null && !string.IsNullOrWhiteSpace(filterContext.RouteData.Values["lang"].ToString())) { ///从路由数据(url)里设置语言 var lang = filterContext.RouteData.Values["lang"].ToString(); Thread.CurrentThread.CurrentUICulture = CultureInfo.CreateSpecificCulture(lang); } else { ///从cookie里读取语言设置 var cookie = filterContext.HttpContext.Request.Cookies["ShaunXu.MvcLocalization.CurrentUICulture"]; var langHeader = string.Empty; if (cookie != null) { ///根据cookie设置语言 langHeader = cookie.Value; Thread.CurrentThread.CurrentUICulture = CultureInfo.CreateSpecificCulture(langHeader); } else { ///如果读取cookie失败则设置默认语言 langHeader = filterContext.HttpContext.Request.UserLanguages[0]; Thread.CurrentThread.CurrentUICulture = CultureInfo.CreateSpecificCulture(langHeader); } ///把语言值设置到路由值里 filterContext.RouteData.Values["lang"] = langHeader; } /// 把设置保存进cookie HttpCookie _cookie = new HttpCookie("ShaunXu.MvcLocalization.CurrentUICulture", Thread.CurrentThread.CurrentUICulture.Name); _cookie.Expires = DateTime.Now.AddYears(1); filterContext.HttpContext.Response.SetCookie(_cookie); base.OnActionExecuting(filterContext); } } }
4、创建一个Controller：
using MultiMVCWebApp.Filters; using System; using System.Collections.Generic; using System.Linq; using System.Web; using System.Web.Mvc; namespace MultiMVCWebApp.Controllers { [Localization] public class LangTestController : Controller { // GET: LangTest public ActionResult Index() { ViewBag.Title = Resources.Gloable.Name; ViewBag.Name = Resources.Gloable.Name; ViewBag.Password = Resources.Gloable.Password; return View(); } } }
5、配置路由：
using System; using System.Collections.Generic; using System.Linq; using System.Web; using System.Web.Mvc; using System.Web.Routing; namespace MultiMVCWebApp { public class RouteConfig { public static void RegisterRoutes(RouteCollection routes) { routes.IgnoreRoute("{resource}.axd/{*pathInfo}"); routes.MapRoute( "Localization", // 路由名称 "{lang}/{controller}/{action}/{id}", // 带有参数的 URL new { controller = "Home", action = "Index", id = UrlParameter.Optional }//参数默认值 ); routes.MapRoute( name: "Default", url: "{controller}/{action}/{id}", defaults: new { controller = "Home", action = "Index", id = UrlParameter.Optional } ); } } }
6、视图View设置：
1）_Layout视图:
<!DOCTYPE html> <html> <head> <meta charset="utf-8" /> <meta name="viewport" content="width=device-width, initial-scale=1.0"> <title>@ViewBag.Title</title> @Styles.Render("~/Content/css") @Scripts.Render("~/bundles/modernizr") </head> <body> <div class="navbar navbar-inverse navbar-fixed-top"> <div class="container"> <div class="navbar-header"> <button type="button" class="navbar-toggle" data-toggle="collapse" data-target=".navbar-collapse"> <span class="icon-bar"></span> <span class="icon-bar"></span> <span class="icon-bar"></span> </button> @Html.ActionLink(@Resources.Gloable.AppName, "Index", "Home", new { area = "" }, new { @class = "navbar-brand" }) </div> <div class="navbar-collapse collapse"> <ul class="nav navbar-nav"> <li>@Html.ActionLink(@Resources.Gloable.Home, "Index", "Home")</li> <li>@Html.ActionLink(@Resources.Gloable.About, "About", "Home")</li> <li>@Html.ActionLink(@Resources.Gloable.Contact, "Contact", "Home")</li> </ul> @Html.Partial("_LoginPartial") </div> </div> </div> <div class="container body-content"> @RenderBody() <hr /> <footer> <p>© @DateTime.Now.Year - My ASP.NET Application</p> </footer> </div> @Scripts.Render("~/bundles/jquery") @Scripts.Render("~/bundles/bootstrap") @RenderSection("scripts", required: false) </body> </html>
2)_LoginPartial视图：
@using Microsoft.AspNet.Identity @if (Request.IsAuthenticated) { using (Html.BeginForm("LogOff", "Account", FormMethod.Post, new { id = "logoutForm", @class = "navbar-right" })) { @Html.AntiForgeryToken() <ul class="nav navbar-nav navbar-right"> <li> @Html.ActionLink("Hello " + User.Identity.GetUserName() + "!", "Index", "Manage", routeValues: null, htmlAttributes: new { title = "Manage" }) </li> <li><a href="javascript:document.getElementById('logoutForm').submit()">Log off</a></li> </ul> } } else { <ul class="nav navbar-nav navbar-right"> <li>@Html.ActionLink(@Resources.Gloable.Register, "Register", "Account", routeValues: null, htmlAttributes: new { id = "registerLink" })</li> <li>@Html.ActionLink(@Resources.Gloable.Login, "Login", "Account", routeValues: null, htmlAttributes: new { id = "loginLink" })</li> </ul> }
3）LangTestController中的Index视图：
@{ ViewBag.Title = ViewBag.Title; } @ViewBag.Title <br /> @ViewBag.Name <br /> @ViewBag.Password <br />
7、效果：
1）英文效果图，链接 http://localhost:10297/en/LangTest/Index
2）中文效果图，链接 http://localhost:10297/cn/LangTest/Index
