具体实现方法
定义实体类
通过Display属性定义Name ResourceType,需要读取的语言库资源文件image.png
生成资源文件
通过mvc scaffolding扩展工具会自动生成对应实体对象的3个资源文件默认中文,繁体,英文
繁体需要自己翻译,英文内容根据字段名定义后已大写字母分割 DateTime 现实 Date Timeimage.png
页面功能按钮语言资源文件库

JS代码
/* multiple lang dropdown */ $('#dropdownlang-dropdown-menu').on('click', 'a', function () { const lang = this.text; const flag = this.firstElementChild.className; const culture = this.firstElementChild.getAttribute("culture"); $('#dropdownlang').children()[0].className = flag; $('#dropdownlang').children()[1].innerHTML = lang; localStorage.setItem('lang-text', lang); localStorage.setItem('lang-css', flag); localStorage.setItem('lang-culture', culture); $.get('/Account/SetCulture?lang=' + culture).then(res => { if (res.success) { location.reload(); } }); }); $(function () { const.getItem('lang-text'); const css = localStorage.getItem('lang-css'); const culture = localStorage.getItem('lang-culture'); scripttag = document.createElement("script"); scripttag.type = "text/javascript"; scripttag.src = src; document.body.appendChild(scripttag); $.parser.parse(); }; if (lang && css && culture) { $('#dropdownlang').children()[0].className = css; $('#dropdownlang').children()[1].innerHTML = lang; } });
后端代码
[HttpGet] public ActionResult SetCulture(string lang) { //这里设置CultureInfo是多余的 switch (lang.Trim()) { case "en": CultureInfo.CurrentCulture = new CultureInfo("en-US"); CultureInfo.CurrentUICulture = new CultureInfo("en-US"); break; case "cn": CultureInfo.CurrentCulture = new CultureInfo("zh-CN"); CultureInfo.CurrentUICulture = new CultureInfo("zh-CN"); break; case "tw": CultureInfo.CurrentCulture = new CultureInfo("zh-TW"); CultureInfo.CurrentUICulture = new CultureInfo("zh-TW"); break; } //这里设置CultureInfo是多余的 var cookie = new HttpCookie("culture", lang) { Expires = DateTime.Now.AddYears(1) }; Response.Cookies.Add(cookie); return Json(new { success = true }, JsonRequestBehavior.AllowGet); }
CultureFilter 这是关键 这是没有使用RouteData,通过修改url来保存当前语言要改的地方很多还要修改路由规则,所以我就用Cookies来保存
public class CultureFilter : IAuthorizationFilter { private readonly string defaultCulture; public CultureFilter() { this.defaultCulture = "cn"; } public void OnAuthorization(AuthorizationContext filterContext) { var culture = filterContext.HttpContext.Request.Cookies["culture"]; var; if (culture != null && culture.Value != null) {.Value; filterContext.HttpContext.Response.Cookies.Set(culture); } switch (lang.Trim()) { case "en": CultureInfo.CurrentCulture = new CultureInfo("en-US"); CultureInfo.CurrentUICulture = new CultureInfo("en-US"); //Thread.CurrentThread.CurrentUICulture = new CultureInfo("en-US"); //Thread.CurrentThread.CurrentCulture = new CultureInfo("en-US"); break; case "cn": CultureInfo.CurrentCulture = new CultureInfo("zh-CN"); CultureInfo.CurrentUICulture = new CultureInfo("zh-CN"); //Thread.CurrentThread.CurrentUICulture = new CultureInfo("zh-CN"); //Thread.CurrentThread.CurrentCulture = new CultureInfo("zh-CN"); break; case "tw": CultureInfo.CurrentCulture = new CultureInfo("zh-TW"); CultureInfo.CurrentUICulture = new CultureInfo("zh-TW"); //Thread.CurrentThread.CurrentUICulture = new CultureInfo("zh-TW"); //Thread.CurrentThread.CurrentCulture = new CultureInfo("zh-TW"); break; } } }
HtmlHelper 代码实现语言的输出
/// <summary> /// 多语言切换 /// </summary> /// <param name="helper"></param> /// <param name="name"></param> /// <returns></returns> public static HtmlString L(this HtmlHelper helper, string name) { var resource = new System.Resources.ResourceManager(typeof(WebApp.resource.Global)); var text = resource.GetString(name); return new HtmlString(text ?? name); } /// <summary> /// 前端easyui或是其它js相关的比如提示信息也需要转换必须在这里加载不同的语言文件 /// </summary> public static HtmlString LangScriptTag(this HtmlHelper helper,string defaultsrc) { var src = defaultsrc; var.CurrentCulture.Name; switch (lang) { case "en-US": src = "/Scripts/easyui/locale/easyui-lang-en.js"; break; case "zh-CN": src = "/Scripts/easyui/locale/easyui-lang-zh_CN.js"; break; case "zh-TW": src = "/Scripts/easyui/locale/easyui-lang-zh_TW.js"; break; default: src = defaultsrc; break; } return new HtmlString($"<script src=\"{ src }\"></script>"); } //html代码 <div class="btn-group btn-group-sm"> <button onclick="append()" class="btn btn-default"> <i class="fa fa-plus"></i> @Html.L("Add") </button> </div> <div class="btn-group btn-group-sm"> <button onclick="removeit()" class="btn btn-default"> <i class="fa fa-trash-o"></i> @Html.L("Delete") </button> </div> <div class="btn-group btn-group-sm"> <button onclick="accept()" class="btn btn-default"> <i class="fa fa-floppy-o"></i> @Html.L("Save") </button> </div>
