MVC 6 .net核心复杂模型绑定 [英] MVC 6 .net Core complex model binding

问题描述

亲爱的所有人，

我在asp .net Core MVC中遇到了与JSON数据绑定有关的问题，如下所示。

我正在尝试使用JObject将复杂对象绑定到模型。

例如我有以下模型

公共级代理会员

    {

        public short TypeID {get;组; }¥b $ b        public string TypeDescription {get;组; }¥b $ b        public string Name {get;组; }¥b $ b    }


   公共类货币

    {

       公共短ID {get;组; }¥b $ b        public string说明{get;组; }¥b $ b    }


   公共类EventViewModel

    {

        public short TypeID {get;组; }¥b $ b        public string TypeDescription {get;组; }


       公共代理会员新郎{get;组; }


       公众代理会员新娘{get;组; }


       公共日期时间？日期{get;组; }


  &NBSP; &NBSP; &NBSP;公共列表< ActingMember>代理成员{得到;组; }¥b $ b  &NBSP; &NBSP; &NBSP; public string Title {get;组; }¥b $ b  &NBSP; &NBSP; &NBSP; public float EstimatedBudget {get;组; }¥b $ b  &NBSP; &NBSP; &NBSP;公共货币EventCurrency {get;组; }¥b $ b  &NBSP; &NBSP; &NBSP; public float PlannerUserID {get;组; }


  &NBSP; }

我收到以下json

{{ " Groom.Name"： " ashgfgdag" " Bride.Name"：" kdehfuhsw"， " Date"：" 10/12/2016 16：12"， " TypeID"：" 1"，  " TypeDescription"："ՀԱՐՍԱՆՅԱՑ
ՀԱՆԴԵՍ"， "" Groom.TypeID"：" 1" " Bride.TypeID"：" 2" " __ RequestVerificationToken" ;：" CfDJ8H_lOK0aUONNs2PK1G9HGekbe8E-2AxE6xdE7wkAFdmUUjFCN3AFJ0Ury7aUciklORzjha0we3vEGhUJyS-PIIQrwuPsEt-w3l1iyEYwhEv0AZmRY8EFEOGJRV9QwFiKyUXy5UE43odB0JipIsC9k6QQ4N-K1LPs4ap_eLyD_piTdjI0wN4MSs8-q2c1DgoU7g"}}

第一级性能，通常结合（日期， TypeID等）但新娘和新郎类型的ActingMember之类的复杂属性没有绑定，点分隔的json属性未映射到此属性。

<这是绑定g part

  &NBSP; &NBSP; &NBSP; [HttpPost]

  &NBSP; &NBSP; &NBSP; [授权]

  &NBSP; &NBSP; &NBSP; public IActionResult Create（[FromBody] JObject jsonData）

  &NBSP; &NBSP; &NBSP; {

  &NBSP; &NBSP; &NBSP; &NBSP; &NBSP; EventViewModel model = jsonData [" viewModel"]。ToObject< EventViewModel>（）;

  &NBSP; &NBSP; &NBSP; &NBSP; &NBSP; .................................

  &NBSP; &NBSP; &NBSP;  }

请告诉我如何解决这个问题。

Dear All,

I have a problem related JSON data binding in asp .net Core MVC which is the following.

I'm trying to bind a complex object to a model using JObject.

For example I have the Following models

public class ActingMember
    {
        public short TypeID { get; set; }
        public string TypeDescription { get; set; }
        public string Name { get; set; }
    }

    public class Currency
    {
        public short ID { get; set; }
        public string Description { get; set; }
    }

    public class EventViewModel
    {
        public short TypeID { get; set; }
        public string TypeDescription { get; set; }

        public ActingMember Groom { get; set; }

        public ActingMember Bride { get; set; }

        public DateTime? Date { get; set; }

        public List<ActingMember> ActingMembers { get; set; }
        public string Title { get; set; }
        public float EstimatedBudget { get; set; }
        public Currency EventCurrency { get; set; }
        public float PlannerUserID { get; set; }

    }

I receive the following json

{{  "Groom.Name": "ashgfgdag",  "Bride.Name": "kdehfuhsw",  "Date": "10/12/2016 16:12",  "TypeID": "1",  "TypeDescription": "ՀԱՐՍԱՆՅԱՑ ՀԱՆԴԵՍ",  "Groom.TypeID": "1",  "Bride.TypeID": "2",  "__RequestVerificationToken": "CfDJ8H_lOK0aUONNs2PK1G9HGekbe8E-2AxE6xdE7wkAFdmUUjFCN3AFJ0Ury7aUciklORzjha0we3vEGhUJyS-PIIQrwuPsEt-w3l1iyEYwhEv0AZmRY8EFEOGJRV9QwFiKyUXy5UE43odB0JipIsC9k6QQ4N-K1LPs4ap_eLyD_piTdjI0wN4MSs8-q2c1DgoU7g"}}

The first level properties are binding normally (Date, TypeID etc.) but the complex properties like Bride and Groom type of ActingMember are not binded the dot separated json properties are not mapped to this properties.

here is the binding part

        [HttpPost]
        [Authorize]
        public IActionResult Create([FromBody] JObject jsonData)
        {
            EventViewModel model = jsonData["viewModel"].ToObject<EventViewModel>();

            .................................

         }

Could you please tell me how I can I solve this issue.
