Question

我正在使用CurrentPage.GetPropertyValue（＆＃34; promo＆＃34;）但是每个不循环使用了

    @{

  var SiteLinks = CurrentPage.GetPropertyValue("promo");
    if (CurrentPage.HasValue("promo"))
    {
        var promoListValue = CurrentPage.GetPropertyValue("promo");

     foreach (var item in promoListValue)
            {
                <span>@item.alias </span>
            }


    }
}

我收到错误但是当我打印promoListValue时它会显示如下

[ { "alias": "1", "content": "1", "img": "/media/1069/509253678.jpg" }, { "alias": "Slide 2", "content": "2", "img": "/media/1074/636609180.jpg" } ]

有人可以帮助我：）

即使我已经创建了一个属性值转换器，所以代码就像这样

@inherits Umbraco.Web.Mvc.UmbracoTemplatePage<ContentModels.HomePage>
@using ContentModels = Umbraco.Web.PublishedContentModels;
@using System.Web.Script.Serialization;
@using Newtonsoft.Json.Linq;
@using System.Collections.Generic;
@using Umbraco.Core.Models.PublishedContent;
@using Umbraco.Core.PropertyEditors;
@using Newtonsoft.Json;
@using System.Linq;


@{
  Layout = "Master1.cshtml";
}



@{

    if (CurrentPage.HasValue("promo"))
    {
        var promoListValue = CurrentPage.GetPropertyValue("promo");



    @* var serializer = new JavaScriptSerializer();
     string json =  serializer.Serialize(promoListValue);
      var testmodel  = serializer.DeserializeObject(json);


    foreach (var item in promoListValue)
            {
                <span>@item </span>
            }  

           @Html.Raw(json) 
            @Html.Raw(Json.Encode(json))

             @Html.Raw(testmodel)  *@

            var obj = Model.Content.GetPropertyValue<MyLookAlikeArchetypeModel>("promo");
            <span>@obj </span>


    } 



}

    public object ConvertSourceToObject(PublishedPropertyType propertyType, object source, bool preview)

}
}

但是var obj = Model.Content.GetPropertyValue<MyLookAlikeArchetypeModel>("promo");

obj正空着
