MVC项目中WebViewPage的实战应用

由于公司的项目可能会卖到国外，所以需要支持多语言。今天我就在目前的项目中实现了多语言功能，下面记录我的具体实现。

 

1、相信很多朋友在用MVC做项目时候，都会遇到“视图必须派生自 WebViewPage 或 WebViewPage<TModel>”的错误。正如错误描述一样，MVC的视图都必须继承WebViewPage。

     自定义WebViewPage类：

     

    /// <summary>
    /// 
    /// </summary>
    /// <remarks>
    /// 恒通2.0 add by zhangfj 2016/12/27
    /// </remarks>
    /// <typeparam name="TModel"></typeparam>
    public abstract class HTView<TModel> : System.Web.Mvc.WebViewPage<TModel>
    {
        private ILocaleStringResourceService _localeStringResourceService
        {
            get { return Engine.Resolve<ILocaleStringResourceService>(); }
        }
        private Localizer _localizer;
        public Localizer Z
        {
            get
            {
                if (_localizer == null)
                {
                    _localizer = (format, args) =>
                    {
                        var resFormat = _localeStringResourceService.GetResource(format, 1);
                        if (string.IsNullOrEmpty(resFormat))
                        {
                            return new LocalizedString(format);
                        }
                        return
                            new LocalizedString((args == null || args.Length == 0)
                                                    ? resFormat
                                                    : string.Format(resFormat, args));
                    };
                }
                return _localizer;
            }
        }
        public override void InitHelpers()
        {
            base.InitHelpers();
        }

        public override string Layout
        {
            get
            {
                var layout = base.Layout;

                if (!string.IsNullOrEmpty(layout))
                {
                    var filename = Path.GetFileNameWithoutExtension(layout);
                    ViewEngineResult viewResult = System.Web.Mvc.ViewEngines.Engines.FindView(ViewContext.Controller.ControllerContext, filename, "");

                    if (viewResult.View != null && viewResult.View is RazorView)
                    {
                        layout = (viewResult.View as RazorView).ViewPath;
                    }
                }

                return layout;
            }
            set
            {
                base.Layout = value;
            }
        }
    }

然后，在Views配置文件中配置WebViewPage视图派生类为我们的自定义类:

    <pages pageBaseType="IOV.Application.WebBiz.HTView">
      <namespaces>
        <add namespace="System.Web.Mvc" />
        <add namespace="System.Web.Mvc.Ajax" />
        <add namespace="System.Web.Mvc.Html" />
        <add namespace="System.Web.Optimization"/>
        <add namespace="System.Web.Routing" />
        <add namespace="IOV.Application.Web" />
      </namespaces>
    </pages>

最后，在视图中就可以使用我们自定义的WebViewPage：

        <div class="login-container">
            <div class="loginbox">
                <div class="loginbox-title">
                </div>
                <div class="loginbox-or">
                    <div class="or">@Z("Account.userLogin")@*用户登录*@</div>
                </div>

                <div class="loginbox-textbox">
                    <input type="text" class="form-control" placeholder="@Z("Account.userName")@*用户名*@" id="txtLoginName" value="admin" />
                </div>
                <div class="loginbox-textbox">
                    <input type="password" class="form-control-pwd" placeholder="@Z("Account.pwd")@*密码*@" id="txtPassWord" value="123456" />
                </div>

                <div class="col-xs-12"><span class="error-info text-danger" id="lblmsgLogin" style="margin-left: 5px"></span></div>

                <div class="loginbox-submit" style="width: 100%; padding-left: 20px">
                    <input type="button" id="btnLogin" class="btn btn btn-block" onclick="DoLogin()" value="@Z("Account.login")@*登录*@">
                </div>
            </div>
            <div class="logobox">
