从网络响应中迭代动态对象

Question

我的结果集中包含一个 id 字段，该字段来自我存储为动态对象的 Web 响应。

{

  "filterFields": [

    {

      "connectionName": "metis_dev",

      "querySourceCategoryName": "dbo",

      "sourceFieldName": "DealerGroupId",

      "sourceFieldVisible": true,

      "reportPartTitle": null,

      "querySourceFieldId": "d313dc65-3d63-4682-8c80-6ab0f235b1d7",

      "querySourceType": "Table",

      "querySourceId": "ac13435a-98b1-4ea9-97af-815b67842334",

      "relationshipId": null,

      "alias": "DealerGroupId",

      "position": 1,

      "visible": true,

      "required": false,

      "operatorSetting": null,

      "value": "4967",

      "dataFormatId": null,

    }

  ]

}

当我在运行时将鼠标悬停在根对象上时，其中一个值就是上面的filterFields对象。但是当我说 时foreach(var filterField in root.filterFields)，我会得到一个错误，因为filterField结果中不存在。我应该如何访问该filterFields集合以便获得我正在寻找的“id”属性？我想filterFields从结果中循环，但我现在无法做到。

想通了这一点。必须将该项目转换为 JToken，这样就完成了。JObject root= JObject.Parse(item.Root.ToString());                foreach (JToken rootItem in root.SelectToken("filterFields"))                {                   var id = rootItem["id"];                }
