无法将当前JSON数组（例如[1,2,3]）反序列化为具有复杂和嵌套对象的类型(Cannot deserialize the current JSON array (e.g. [1,2,3]) into type with complex and nested objects)

 我正在尝试为复杂的对象构建web api。 为此，我构建了自定义绑定器，从JSON反序列化此对象。 
 
 我的客户活页夹看起来像： 
 
var paramType = p_BindingContext.ModelType;

    dynamic updatedParam = Activator.CreateInstance(paramType);

    JsonReader reader = new JTokenReader(JObject.Parse
    (p_ActionContext.Request.Content.ReadAsStringAsync().Result));

    JObject jObject = JObject.Load(reader);

    JsonSerializer serializer = new JsonSerializer();

    serializer.Populate(jObject.CreateReader(), updatedParam);//Here the exception thorws

    p_BindingContext.Model = updatedParam; 
 
 序列化的对象非常复杂： 
 
          public class ModelRegisterUserRequest{

              public ModelUser User { get; set; }

    public CampaignItem CampaignWithChosenProposal { get; set; }

    public string ValidationToken { get; set; }

    public string IVRToken { get; set; }

    public string DealerID { get; set; }

    public string SalePersonID { get; set; }
             }

public class CampaignItem
{

    public List<BannerItem> Banners { get; set; }

    public string Code { get; set; }

    public string CustomerInstruction { get; set; }

    public string InfoLink { get; set; }

    public string LobbySubTitle { get; set; }

    public string LobbyTitle { get; set; }

    public string MoreText { get; set; }

    public uint NumOfColumns { get; set; }

    public uint NumOfRows { get; set; }

    public string OriginString { get; set; }
    public int OriginInt { get; set; }

    public List<ProposalItem> Proposals { get; set; }

    public string RegulationsInfoLink { get; set; }

    public string ServiceType { get; set; }

    public string SubTitle { get; set; }

    public string SWDefault { get; set; }

    public string Title { get; set; }   
}

public partial class ProposalItem
{

    public List<string> EquipmentsCode { get; set; }


    public string FeatureCode { get; set; }


    public string InvalidReason { get; set; }


    public bool IsExistsMoreInfo { get; set; }


    public bool IsValid { get; set; }


    public string LeadCode { get; set; }


    public int ParamCombinationCode { get; set; }


    public string ProductCode { get; set; }


    public string ProductCombinationCode { get; set; }


    public string ProposalCode { get; set; }


    public List<ColumnItem> Columns { get; set; }


    public List<MoreInfoItem> MoreInfoList { get; set; }


    public List<string> PricePlans { get; set; }

    public string ProductName { get; set; }    
 
 } 
 
 Json是使用Javascript代码中的JSON.stringify命令创建的，如下所示：

 在例外情况下抛出异常，看起来像： 
 
Cannot deserialize the current JSON array (e.g. [1,2,3]) into type WebAPI.Models.Entities.Campaigns.CampaignObjects.ProposalItem' because the type requires a JSON object (e.g. {"name":"value"}) to deserialize correctly.
To fix this error either change the JSON to a JSON object (e.g. {"name":"value"}) or change the deserialized type to an array or a type that implements a collection interface (e.g. ICollection, IList) like List<T> that can be deserialized from a JSON array. JsonArrayAttribute can also be added to the type to force it to deserialize from a JSON array.
 
 我花了几个晚上才解决这个异常，但没有找到任何解决方案此网站上的解决方案也被删除但不支持这样复杂的问题。

 有人遇到了这样的JSON意外行为，可以提供帮助吗？ 
 
 谢谢 

I`m trying to build web api for complex object. For this aim I built the custom binder which deserialize this object from JSON.
 
My Customer Binder looks like:
 
var paramType = p_BindingContext.ModelType;

    dynamic updatedParam = Activator.CreateInstance(paramType);

    JsonReader reader = new JTokenReader(JObject.Parse
    (p_ActionContext.Request.Content.ReadAsStringAsync().Result));

    JObject jObject = JObject.Load(reader);

    JsonSerializer serializer = new JsonSerializer();

    serializer.Populate(jObject.CreateReader(), updatedParam);//Here the exception thorws

    p_BindingContext.Model = updatedParam; 
 
The object to serialize is very comlex:
 
          public class ModelRegisterUserRequest{

              public ModelUser User { get; set; }

    public CampaignItem CampaignWithChosenProposal { get; set; }

    public string ValidationToken { get; set; }

    public string IVRToken { get; set; }

    public string DealerID { get; set; }

    public string SalePersonID { get; set; }
             }

public class CampaignItem
{

    public List<BannerItem> Banners { get; set; }

    public string Code { get; set; }

    public string CustomerInstruction { get; set; }

    public string InfoLink { get; set; }

    public string LobbySubTitle { get; set; }

    public string LobbyTitle { get; set; }

    public string MoreText { get; set; }

    public uint NumOfColumns { get; set; }

    public uint NumOfRows { get; set; }

    public string OriginString { get; set; }
    public int OriginInt { get; set; }

    public List<ProposalItem> Proposals { get; set; }

    public string RegulationsInfoLink { get; set; }

    public string ServiceType { get; set; }

    public string SubTitle { get; set; }

    public string SWDefault { get; set; }

    public string Title { get; set; }   
}

public partial class ProposalItem
{

    public List<string> EquipmentsCode { get; set; }


    public string FeatureCode { get; set; }


    public string InvalidReason { get; set; }


    public bool IsExistsMoreInfo { get; set; }


    public bool IsValid { get; set; }


    public string LeadCode { get; set; }


    public int ParamCombinationCode { get; set; }


    public string ProductCode { get; set; }


    public string ProductCombinationCode { get; set; }


    public string ProposalCode { get; set; }


    public List<ColumnItem> Columns { get; set; }


    public List<MoreInfoItem> MoreInfoList { get; set; }


    public List<string> PricePlans { get; set; }

    public string ProductName { get; set; }    
 
}

JsonArrayAttribute can also be added to the type to force it to deserialize from a JSON array.
 
I spent nights for resolve this exception but did not find any solutions Also the solutions on this site are excisted but not supports such complex problem.

Somebody met such JSON unexpected behaiviour and could help?
