c# - 使用 DataContractJsonSerializer 进行序列化时将 JSON 对象保留为字符串

Question

目前，我正在尝试解析来自 API 的动态 JSON 响应。接收到的 JSON 示例如下所示：

 {
  "data": [
    {
      "Id": "XXXXXXXXXXXXXXXXXXXXXXXX",
      "IsActive": true,
      "DateCreated": "2017-11-09T00:01:49.827Z",
      "DateModified": "2017-11-09T00:01:49.827Z",
      "IsDeleted": false,
      "Uid": "XXXXXXXXXXXXXXXXXXXXXXXX",
      "CustomObject": {
        "customdata1": " Store my customdata1 value",
        "customdata2": " Store my customdata2 value"
      }
    }
  ],
  "Count": 1
}

在上面的 JSON 中，序列化时，我希望将 CustomObject 映射到 C# 对象中的字符串。下面是我想要的对象结构的一个例子。

[System.Runtime.Serialization.DataContract]
public class CustomObjectData
{
    [System.Runtime.Serialization.DataMember]
    public string Id { get; set; }
    [System.Runtime.Serialization.DataMember]
    public bool IsActive { get; set; }
    [System.Runtime.Serialization.DataMember]
    public string DateCreated { get; set; }
    [System.Runtime.Serialization.DataMember]
    public string DateModified { get; set; }
    [System.Runtime.Serialization.DataMember]
    public bool IsDeleted { get; set; }
    [System.Runtime.Serialization.DataMember]
    public string Uid { get; set; }
    [System.Runtime.Serialization.DataMember]
    public string CustomObject { get; set; }
}

[System.Runtime.Serialization.DataContract]
public class CustomObjectDataHolder
{
    [System.Runtime.Serialization.DataMember]
    public List<CustomObjectData> data { get; set; }
    [System.Runtime.Serialization.DataMember]
    public int Count { get; set; }
}

我正在尝试将其开发为 CRM 插件，因此我无法使用其他第三方 JSON 序列化程序，例如 NewtonSoft。
