複雑なオブジェクト用の Web API を構築しようとしています。この目的のために、JSON からこのオブジェクトを逆シリアル化するカスタム バインダーを作成しました。
私の顧客バインダーは次のようになります。
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;
シリアル化するオブジェクトは非常に複雑です。
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 は、Javascript コードから JSON.stringify コマンドで作成され、次のようになります。

シリアル化行で例外がスローされ、次のようになります。
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.
この例外を解決するために夜を過ごしましたが、解決策が見つかりませんでした。また、このサイトの解決策は存在しますが、そのような複雑な問題はサポートされていません。
現在の JSON 配列 ([1,2,3] など) を型に逆シリアル化できません
誰かがそのような JSON の予期しない動作に遭遇し、助けてくれるでしょうか?
ありがとう
