cultureinfo ASP.NET MVC5多语言切换快速实现方案

功能

为了实现动态语言切换，Demo做了三个可以切换的语言库，包括资源文件的定义、实体对象属性的设置、后台代码控制器的实现、iauthorization filter和html helper，易学易用。有了我之前发布的# MVC脚手架智能代码引擎的更新模板中生成多语言资源文件的新功能，我发现我的框架和现在流行的ABP框架差不多，有点像收费版的Asp.net Zero，但是我把它做得更轻，更方便，更快。不幸的是，Asp.net核心下的脚手架扩建并不像MVC5那么容易。这个还需要研究，下一步就是升级到ASP.NET核心。

具体实现方法

定义实体类

名称资源类型是通过显示属性定义的，并且需要要读取的语言库资源文件

生成资源文件

mvc脚手架扩展工具会自动生成三个实体对象对应的资源文件，默认为中文、繁体和英文

繁体中文需要自己翻译，英文内容根据字段名定义后已经被分为大写字母。日期时间现实日期时间

前端和后端代码实现语言切换功能

javascript，javascript

/*多种语言下拉列表*/$(' # dropdownlang-drop down-menu ')。on('click '，' a '，()= >{ const lang = this.textconst flag = this . FIRStElementChild . ClassName；const culture = this . FIRStElementChild . GetAttribute(" culture ")；$('#dropdownlang ')。children()[0]。className =标志；$('#dropdownlang ')。children()[1]。innerHTML = langlocal STORAGE . SetItem(' lang-text '，lang)；localStorage.setItem('lang-css '，标志)；local storage . SetItem(' lang-culture '，区域性)；$.get('/Account/SetCulture？lang=' +文化)。然后(res = >;{ if(RES . success){ location . reload()；} });});$(()= >{ const lang = LocalStorage . GetItem(' lang-text ')；const CSS = LocalStorage . GetItem(' lang-CSS ')；const culture = LocalStorage . GetItem(' lang-culture ')；//这段代码是多余的，完全没有效果//tag = document。("");//tag . type = " text/Java "；//tag . src = src；//document.body .(标记)；//$ . parser . parse()；};if(lang & amp；& ampcss和。& amp区域性){ $('#dropdownlang ')。children()[0]。className = css$('#dropdownlang ')。children()[1]。innerHTML = lang} });

后端代码

[http get]public action result set culture(string lang){//此处的CultureInfo集是冗余开关(lang . trim()){ case " en ":culture info。current culture = new culture info(" en-us ")；CultureInfo。currentui culture = new culture info(" en-US ")；打破；case "cn": CultureInfo。current culture = new culture info(" zh-CN ")；CultureInfo。currentui culture = new culture info(" zh-CN ")；打破；案例“tw”:CultureInfo。current culture = new culture info(" zh-TW ")；CultureInfo。currentui culture = new culture info(" zh-TW ")；打破；}//这里设置的CultureInfo是多余的var cookie = new http cookie(" culture "，lang) {expires = datetime。现在。add years(1)}；回应。cookie . Add(cookie)；返回Json(new { success = true }，JsonRequestBehavior。allow get)；}

这是关键。它不使用RouteData，并且有很多地方可以通过修改url来改变当前的语言，所以我使用Cookies来保存它

公共类CultureFilter:IAuthorizationFilter { private readonly string DefaultCulture；public CultureFilter(){ this . DefaultCulture = " cn "；} public void on authorization(AuthorizationContext filter context){ var culture = filter context。HttpContext . request . Cookies[" culture "]；var lang = defaultCultureif(文化！= null & amp& amp文化。值！= null) { lang =区域性。价值；filterContext。HttpContext . response . Cookies . set(区域性)；} switch (lang。Trim()) { case "en": CultureInfo。current culture = new culture info(" en-US ")；CultureInfo。currentui culture = new culture info(" en-US ")；//线程。current thread . currentui culture = new culture info(" en-US ")；//线程。current thread . current culture = new culture info(" en-US ")；打破；case "cn": CultureInfo。current culture = new culture info(" zh-CN ")；CultureInfo。currentui culture = new culture info(" zh-CN ")；//线程。current thread . currentui culture = new culture info(" zh-CN ")；//线程。current thread . current culture = new culture info(" zh-CN ")；打破；案例“tw”:CultureInfo。current culture = new culture info(" zh-TW ")；CultureInfo。currentui culture = new culture info(" zh-TW ")；//线程。current thread . currentui culture = new culture info(" zh-TW ")；//线程。current thread . current culture = new culture info(" zh-TW ")；打破；} } }

HtmlHelper代码实现语言的输出
