【解決方法】角かっこでjsonを使用してデータテーブルを作成する方法

以下のjson構造を使用してc#でデータテーブルを設定するにはどうすればよいですか

{
  "store": "Barnes Rd. C.S.C.",
  "storeID": 1001,
  "items": [
    {
      "item": "1K AirteltiGO Scratch Card",
      "details": [
        {
          "startSerial": "64235900000",
          "endSerial": "64235900000",
          "quantity": 1
        }
      ]
    }
  ]
}

私が試したこと：

try
           {
               var client = new HttpClient();
               String jsonstring = null;
               int transno = Convert.ToInt32(lbltransactionnumbertovoid.Text);
               int storeid = Convert.ToInt32(Session["StoreID"]);
               client.DefaultRequestHeaders.Authorization = new AuthenticationHeaderValue("Bearer", accessToken);
               client.BaseAddress = new Uri(Constants.BaseApiAddress);
               client.DefaultRequestHeaders.Accept.Clear();
               client.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json"));
               var response = client.GetAsync("url" + storeid + "/" + transno).Result;
               transdetails.Columns.Clear();
               transdetails.Rows.Clear();
               transdetails.Clear();
               //Gridtransactionitemsprint.DataSource = transdetails;
               //Gridtransactionitemsprint.DataBind();
               if (response.IsSuccessStatusCode)
               {
                   jsonstring = response.Content.ReadAsStringAsync().Result;


                   Root deserializedClass = JsonConvert.DeserializeObject<Root>(response.ToString());




                   transdetails = (DataTable)JsonConvert.DeserializeObject(jsonstring, (typeof(DataTable)));
                   if (transdetails != null && transdetails.Rows.Count > 0)
                   {
                       //DataTable DT = new DataTable();
                       gridtransactionsoldserials.DataSource = transdetails;
                       gridtransactionsoldserials.DataBind();
                       ScriptManager.RegisterStartupScript(this, this.GetType(), "Pop", "$('#transactionsoldserials').modal('show');", true);
                   }
                   else
                   {
                       gridtransactionsoldserials.DataSource = transdetails;
                       gridtransactionsoldserials.DataBind();
                       ScriptManager.RegisterStartupScript(this, this.GetType(), "HidePopup", "$('#transactionsoldserials').modal('hide')", true);
                   }
               }
               else
               {
                   gridtransactionsoldserials.DataSource = transdetails;
                   gridtransactionsoldserials.DataBind();
                   ScriptManager.RegisterStartupScript(this, this.GetType(), "Pop", "$('#transactionsoldserials').modal('show');", true);
               }

           }
           catch (Exception ex)
           {
               if (Session["username"] == null)
               {
                   Response.Redirect("Login.aspx");
               }
               else
               {
                   Constants.writelog(Session["username"].ToString() + ":" + Session["StoreId"].ToString() + ":" + ex.Message.ToString() + ":" + "Invoice" + ":" + "Transactionitemserials()" + " " + "method was called");
                   lblmessages.Text = ex.Message.ToString();
                   ScriptManager.RegisterStartupScript(this, this.GetType(), "Pop", "$('#validations').modal('show');", true);
               }
           }
