私の質問はかなり簡単です。 私はAPIに取り組んでおり、エンティティを更新する必要があります。この目的のために、bodyから来るJObjectをKenticoモデルのTreeNode（News）オブジェクトに変換する必要があります。 Kentico：Jsonのオブジェクト（TreeNode）をデシリアライズ
Kenticoのドキュメントを読む
は、右のようです JSonSerializerと呼ばれるオブジェクトがある1：[HttpPut]
[Route("")]
public IHttpActionResult UpdateById([FromBody]JObject updated)
{
CMS.DataCom.JsonSerializer serializer = new CMS.DataCom.JsonSerializer();
var result = serializer.Unserialize<CMS.DocumentEngine.Types.News>(updated.ToString());
DocumentHelper.UpdateDocument(result);
return Ok("record updated.");
}
私の "更新" 対象：
私のAPIは、このようになります正しいJSONを持っています。私はアンシリアライズしようとすると、しかし、私は次のエラーを取得する：
An exception of type 'System.Runtime.Serialization.InvalidDataContractException' occurred in System.Runtime.Serialization.dll but was not handled in user code Additional information: Type 'CMS.DocumentEngine.Types.News' cannot be serialized. Consider marking it with the DataContractAttribute attribute, and marking all of its members you want serialized with the DataMemberAttribute attribute. If the type is a collection, consider marking it with the CollectionDataContractAttribute. See the Microsoft .NET Framework documentation for other supported types.

にです私がすでにデシリアライズしようとしたことに言及することも重要です。System.Web.Script.Serialization.JavaScriptSerializerおよびNewtonsoft.Json.Linq.JToken.ToObjectと、APIのパラメータにクラスを直接置くことによっても動作しませんでした。
どのような考えですか？
これは私が最後にしたものです。すべてのプロパティをTreeNodeオブジェクトにマップするためにDTOを作成しました。ありがとう!! –
