使用 RestSharp 反序列化 JSON 数组

Question

我有以下 JSON 对象被 return 从我无法控制的 API 调用编辑：

{
  "GetBusinessGroupsRestResult": [
  {
    "BgId": 1,
    "NodeLevel": 1,
    "BusinessDescription": "Business Groups",
    "BusinessName": "Root",
    "nodegroupid": 2,
    "nodegroupname": "Root",
    "nodegroupdesc": "Root",
    "sorkkey": "Root",
    "Marked": 2
  },
  {
    "BgId": 2,
    "NodeLevel": 2,
    "BusinessDescription": "Business A",
    "BusinessName": "Business A",
    "ParentID": 1,
    "nodegroupid": 3,
    "nodegroupname": "Business A",
    "nodegroupdesc": "Business A",
    "sorkkey": "Business A",
    "Marked": 2
  },
  ...
 ]
}

我创建了以下 class 结构，试图将其反序列化为 C# 对象实例：

public class GetBusinessGroupsRestResult
{
    public List<BusinessGroup> BusinessGroups { get; set; }
}

public class BusinessGroup
{
    [DeserializeAs(Name = "BgId")]
    public int BusinessGroupId { get; set; }

    public int NodeLevel { get; set; }
    public string BusinessDescription { get; set; }
    public string BusinessName { get; set; }

    [DeserializeAs(Name = "ParentID")]
    public int ParentId { get; set; }

    [DeserializeAs(Name = "nodegroupid")]
    public int NodeGroupId { get; set; }

    [DeserializeAs(Name = "nodegroupname")]
    public string NodeGroupName { get; set; }

    [DeserializeAs(Name = "sorkkey")]
    public string SortKey { get; set; }

    public int Marked { get; set; }
}

我正在尝试使用 RestSharp 将其反序列化，并将 RootElement 指定为 GetBusinessGroupsRestResult。尝试使用 RestSharp 的 IRestResponse<T> Execute<T>(RestRequest) 进行反序列化时，我收到以下错误：

System.InvalidCastException: Unable to cast object of type 'RestSharp.JsonArray' to type 'System.Collections.Generic.IDictionary`2[System.String,System.Object]'.

我已经成功地反序列化了这个 API 之前没有 return 列出的响应，例如：

{
  "AcquireSecurityTokenRestResult": {
    "SecurityToken": "SECURITY-TOKEN",
    "SessionLength": 600000,
    "APIVersion": "VERSION"
  }
}

具有以下 POCO：

public class AcquireSecurityTokenRestResult
{
    public string SecurityToken { get; set; }
    public int SessionLength { get; set; }
    [DeserializeAs(Name = "APIVersion")]
    public string ApiVersion { get; set; }
}

谁能给我指出正确的方向？谢谢！

设法让它发挥作用。 Execute部分：

var client = new RestClient("http://localhost:3000/");
var request = new RestRequest("main", Method.GET);
var response = client.Execute<RootObject>(request);

和 classes:

public class RootObject
{
    public List<BusinessGroup> GetBusinessGroupsRestResult { get; set; }
}

public class BusinessGroup
{
    [DeserializeAs(Name = "BgId")]
    public int BusinessGroupId { get; set; }

    public int NodeLevel { get; set; }
    public string BusinessDescription { get; set; }
    public string BusinessName { get; set; }

    [DeserializeAs(Name = "ParentID")]
    public int ParentId { get; set; }

    [DeserializeAs(Name = "nodegroupid")]
    public int NodeGroupId { get; set; }

    [DeserializeAs(Name = "nodegroupname")]
    public string NodeGroupName { get; set; }

    [DeserializeAs(Name = "nodegroupdesc")]
    public string NodeGroupDesc { get; set; }

    [DeserializeAs(Name = "sorkkey")]
    public string SortKey { get; set; }

    public int Marked { get; set; }
}

由于主要响应是一个对象，其中包含一个名为 GetBusinessGroupsRestResult 的数组，您在根对象中也需要它。

您基本上可以通过将 DeserializeAs 属性添加到 GetBusinessGroupsRestResult class:

中的 BusinessGroups 属性来修复示例

public class GetBusinessGroupsRestResult
{
    [DeserializeAs(Name = "GetBusinessGroupsRestResult")]
    public List<BusinessGroup> BusinessGroups { get; set; }
}

不仅仅是一个答案，一个建议。为什么不使用 Json.NET 而不是使用 RESTSharp？

我运行遇到了在 Json.NET 中运行良好的 RESTSharp 的问题。
