JSONからDataTableへのデシリアライズのトラブル

Question

私はC＃が新しく、APIからのJSONレスポンスをデシリアライズし、DataTable（そしてSQL Server）への応答を再送信しています。

私はJSON.NETとRestSharpを使用しています。

ここではConvert Json String to C# Object Listの概要を説明し、FastMemberを使用してオブジェクトをデータテーブルに変換しようとしていたが、私は不合理だった。ここで

はJSONレスポンスの例である：

IRestResponse response = client.Execute(request); 
      var content = response.Content; 



      //Deserialziing Response to Object 
      var datafromjson = JsonConvert.DeserializeObject<ActivityModels.RootObject>(content); 

      DataTable table = new DataTable(); 


      using (var reader = ObjectReader.Create(datafromjson.data.ToString())) 
      { 
       table.Load(reader); 
      }

私はJSONの構造が私を捨てていると思います。データクラスのデータ型をリストに変更しようとしましたが、JSONを変更したり、オブジェクトを逆シリアル化しているオブジェクトのタイプを変更するように求めるエラーが発生します。

created_atがdatetimeなどであるようないくつかの問題があります。ルートオブジェクトのコードも表示されません。これを試してみてください：
