如何解析不完全对应的json [英] How to parse not fully corresponding json

问题描述

我正在使用第三方API，因此无法更改响应结构. 作为回应，我得到这样的东西:

I am using third-party API, so I cannot change the response structure. In response I am getting something like this:

{
    "Code": "SomeCode",
    "Name": "Some Name",
    "IsActive": true,
    "Prop13": {
        "LongId": "12",
        "ShortId": "45"
    },
    "Prop26": {
        "LongId": "12",
        "ShortId": "45"
    },
    "Prop756": {
        "LongId": "12",
        "ShortId": "45"
    }
}

我需要将其解析为下一个类:

I need to parse it to next type of class:

public class Class1
{
    public string Code { get; set; }

    public string Name { get; set; }

    public bool IsActive { get; set; }

    public Dictionary<string, PropertiesClass> Properties { get; set; }
}

public class PropertiesClass
{
    public int LongId { get; set; }

    public int ShortId { get; set; }
}

属性"Prop13"，"Prop26"等是动态响应的，可能都不存在，或者名称完全不同.因此，我必须仅将Code，Name和IsActive(始终存在)存储到类属性中，所有其他属性都应存储在Dictionary中.属性名称应作为键存储在字典中.

Properties "Prop13", "Prop26" etc are dynamic in response, there could none of them, or with completely other name. So I must store only Code, Name and IsActive (this are always present) to class properties, all other should go to the Dictionary. And the name of the property should be stored as a key in the dictionary.

推荐答案

我可以想到一种方法.

您的Class1需要稍作修改:

public class Class1
{
    public string Code { get; set; }

    public string Name { get; set; }

    public bool IsActive { get; set; }

    [JsonExtensionData]
    public Dictionary<string, JToken> _JTokenProperty { get; set; }

    public Dictionary<string, PropertiesClass> Properties1 { get; set; } = new Dictionary<string, PropertiesClass>();
}

然后在解析对象的位置，您要像这样对它进行解析:

Then where you parse the object, you want to pare it like so:

var obj = JsonConvert.DeserializeObject<Class1>("{\"Code\":\"SomeCode\",\"Name\":\"Some Name\",\"IsActive\":true,\"Prop13\":{\"LongId\":\"12\",\"ShortId\":\"45\"},\"Prop26\":{\"LongId\":\"12\",\"ShortId\":\"45\"},\"Prop756\":{\"LongId\":\"12\",\"ShortId\":\"45\"}}");

foreach(KeyValuePair<string, JToken> token in obj._JTokenProperty)
{
    obj.Properties1.Add(token.Key, token.Value.ToObject<PropertiesClass>());
}

这将生成所需的输出.

感谢@Nkosi提供的链接和建议，使其保持独立. 您可以将以下内容添加到Class1

Thanks to @Nkosi for the link and suggestion to keep it self-contained. You would add the following to Class1

[OnDeserialized]
private void OnDeserialized(StreamingContext context)
{

    foreach (KeyValuePair<string, JToken> token in _JTokenProperty)
    {
        Properties1.Add(token.Key, token.Value.ToObject<PropertiesClass>());
    }
}

您的反序列化变为:

var obj = JsonConvert.DeserializeObject<Class1>("{\"Code\":\"SomeCode\",\"Name\":\"Some Name\",\"IsActive\":true,\"Prop13\":{\"LongId\":\"12\",\"ShortId\":\"45\"},\"Prop26\":{\"LongId\":\"12\",\"ShortId\":\"45\"},\"Prop756\":{\"LongId\":\"12\",\"ShortId\":\"45\"}}");
