c# - Json.NET 未能将 Json 反序列化为仅字段类

Question

我想用 Newtonsoft Json.NET 解析一段 JSON

JSON:

{

    "USER":{
        "result_id":"0",
        "result_description":"NET Connections",
        "cmlog_username":[
            "8118236834",
            "8118236834",
            "8118236834"
        ],
        "caller_id":[
            "14cc20f7b05f",
            "14cc20f7b05f",
            "14cc20f7b05f"
        ]
    }

}

类

 public class USER
        {
            public string result_id;
            public string result_description;
            public string[] cmlog_username;
            public string[] caller_id;
        }//USER

我用下面的代码转换它，但所有的属性值都是 NULL

USER con = JsonConvert.DeserializeObject<USER>(msg);

Answer 1

您的反序列化类不正确。将您的 JSON 放入 json2csharp.com产生:

public class USER
{
    public string result_id { get; set; }
    public string result_description { get; set; }
    public List<string> cmlog_username { get; set; }
    public List<string> caller_id { get; set; }
}

public class RootObject
{
    public USER USER { get; set; }
}

所以你需要做:

User con = JsonConvert.DeserializeObject<RootObject>(msg);

您的 JSON 对象不是 USER，它是一个包含 USER 的对象。
