反序列化对象 returns null 尝试映射时嵌套 JSON

Question

我知道这个问题看起来很熟悉，但就我而言，有点不同。

我已经使用 API returns 格式的 XML 数据。
获取 API 响应并将其转换为 JSON 格式，以便我能够进行映射。

我的问题，当我 DeserializeObject 它总是 returns null 并且我不太确定这是否是由映射引起的。

问题：如何反序列化嵌套的 JSON 对象以映射字段？如果我必须在将 XML 转换为 JSON

方面进行更改，也请指导我

谢谢！

正在将 XML 响应转换为 JSON

            var result = await client.GetAsync($"url");

            var xml = result.Content.ReadAsStringAsync().Result;
            XmlDocument doc = new XmlDocument();
            doc.LoadXml(xml);
            string json = JsonConvert.SerializeXmlNode(doc);

            //the results hear is null for all the properties
            var des = (AccountLite)Newtonsoft.Json.JsonConvert.DeserializeObject(json, typeof(AccountLite));
            Console.WriteLine(des);
            Console.ReadLine();

JSON 对象

{
"MessageEnvelope": {
    "ListOfAccountLite": {
        "AccountLite": [
            {
                "Id": "",
                "AccountStatus": "",
                "AccountTypeCode": "",
                "CSN": "",
                "Location": "",
                "MasterAccountId": "",
                "Name": ""
            },
            {
                "Id": "",
                "AccountStatus": "",
                "AccountTypeCode": "",
                "CSN": "",
                "Location": "",
                "MasterAccountId": "",
                "Name": ""
            },
            {
                "Id": "",
                "AccountStatus": "",
                "AccountTypeCode": "",
                "CSN": "",
                "Location": "",
                "MasterAccountId": "",
                "Name": ""
            }
        ]
    }   
}
}

C#生成class基于JSON对象

public partial class Welcome
{
    [JsonProperty("MessageEnvelope")]
    public MessageEnvelope MessageEnvelope { get; set; }
}

public partial class MessageEnvelope
{
    [JsonProperty("ListOfAccountLite")]
    public ListOfAccountLite ListOfAccountLite { get; set; }
}

public partial class ListOfAccountLite
{
    [JsonProperty("AccountLite")]
    public AccountLite[] AccountLite { get; set; }
}

public partial class AccountLite
{
    [JsonProperty("Id")]
    public string Id { get; set; }

    [JsonProperty("AccountStatus")]
    public string AccountStatus { get; set; }

    [JsonProperty("AccountTypeCode")]
    public string AccountTypeCode { get; set; }

    [JsonProperty("CSN")]
    public string Csn { get; set; }

    [JsonProperty("Location")]
    public string Location { get; set; }

    [JsonProperty("MasterAccountId")]
    public string MasterAccountId { get; set; }

    [JsonProperty("Name")]
    public string Name { get; set; }
}

简单地反序列化到根 class Welcome 而不是 AccountLite.

//var des = (AccountLite)Newtonsoft.Json.JsonConvert.DeserializeObject(json, typeof(AccountLite));

Welcome welcome = JsonConvert.DeserializeObject<Welcome>(json);

反序列化对象 returns null 尝试映射时嵌套 JSON

Deserialize Object returns null with nested JSON when trying to map it
