ABP的语言本地化设置非常方便，甚至地区图标ABP框架都已经有了。
先看看结果吧。
英文的界面
中文的界面
配置流程如下：
首先在Localization目录下新建一个对应的json文件，里面存放对应变量的本地化字符串，命名规则就是 应用名-本地化简称.json
比如我的应用名叫做SimpTaskApp(没错，就是abp的入门教程的工程)，然后中文的简写是zh，所以我的json文件就是SimpleTaskApp-zh.json。
然后来看看内容
json里主要是两个属性culture和texts。
culture对应文化的简称。中文zh 英文en 土耳其文tr
texts对应字符串变量。
这里配置好以后就在XXXLocalizationConfigurer.cs里添加语言。XXX是应用名
位置在这里。
localizationConfiguration.Languages集合里添加一个LanguageInfo对象，参数3个，第一个是语言简写，如中文是zh，第二个是显示的名称，第三个是图标，一般是国家或地区的标志，规则是famfamfam-flags XX，XX是国家或地区的简写，如中国 cn
这段就是那个下拉选择语言的前端代码，遍历Model里的Language集合，加入下拉菜单。
1 @model Acme.SimpleTaskApp.Web.Views.Shared.Components.LanguageSelection.LanguageSelectionViewModel 2 <li class="dropdown"> 3 <a href="#" class="dropdown-toggle" data-toggle="dropdown"> 4 <div class="@Model.CurrentLanguage.Icon"></div> 5 <span>@Model.CurrentLanguage.DisplayName</span> 6 <b class="caret"></b> 7 </a> 8 <ul class="dropdown-menu"> 9 @foreach (var language in Model.Languages) 10 { 11 if (language.Name != Model.CurrentLanguage.Name) 12 { 13 <li><a href="@Url.Action("ChangeCulture", "AbpLocalization")?cultureName=@(language.Name)&returnUrl=@(Model.CurrentUrl)"><div class="@language.Icon"></div> @language.DisplayName</a></li> 14 } 15 } 16 </ul> 17 </li>
最后的效果就如下
