注意：我也使用here的模板和AspNetBoilerplate标签帮助程序，因此bc-属性和form-group标签是有效的。
我正在尝试将模型发布到我的一个应用程序服务中。但是我收到以下错误
”验证期间检测到以下错误。 ↵-无法反序列化当前JSON对象（例如{“ name”：“ value”}）为类型'System.Collections.Generic.IList`1 [App.Stores.StoreWalk.Dtos.CreateOrEditStoreWalkCategoryDto]'，因为该类型需要JSON数组（例如[1,2,3]）正确反序列化。 ↵要解决此错误，请将JSON更改为JSON数组（例如[1,2,3]）或更改反序列化类型，使其成为常规.NET类型（例如，不是整数之类的原始类型，而不是一个集合类型） （例如数组或列表），可以从JSON对象反序列化。还可以将JsonObjectAttribute添加到类型中，以强制其从JSON对象反序列化。 ↵路径'categories.0'，第1行，位置84。 ↵“消息：“您的请求无效！” validationErrors：[{...}] proto ：对象
我了解错误的含义，但我不知道如何解决我的代码。
在2条建议中，To fix this error either change the JSON to a JSON array (e.g. [1,2,3])是我必须采取的方法。
可能不适合我，但是我在玩我的代码，并注意到从@i属性中删除@j和name时发现可以成功发布，但是单选按钮丢失了所有功能（由于命名冲突，单击第二行会更改第一行），而且，我认为需要索引来保持它们唯一（我仍在学习，如果我写错了，请纠正我）。
即时通讯发回的json字符串是通过调用$('form[name=StoreWalkForm]').serializeFormToObject()创建的，该字符串如下所示，并使用Mecons
$.fn.serializeFormToObject = function() {
var $form = $(this);
var fields = $form.find('[disabled]');
fields.prop('disabled', false);
var json = $form.serializeJSON();
fields.prop('disabled', true);
return json;
};
