[英]Parse json nested array into c# object
I´m need to parse a json object into ac# class, my problem is that json object has a nested array and it´s throwing some errors when parsing.我需要将 json 对象解析为 ac# 类,我的问题是 json 对象有一个嵌套数组,并且在解析时会抛出一些错误。
I have tried a couple of options: a) do foreach in the elements of nested array, and add them to a new array b) parsing using json.deserialize我尝试了几个选项:a)在嵌套数组的元素中执行 foreach,并将它们添加到新数组 b)使用 json.deserialize 解析
No success so far至今没有成功
These are my c# classes
public class itemPrediccion
{
public string ClavePartido { get; set; }
public string Ganador { get; set; }
public bool EsFavorito { get; set; }
}
public class Prediccion
{
public ObjectId _id { get; set; }
public string IdUsuario { get; set; }
public int Jornada { get; set; }
public IEnumerable<itemPrediccion> PrediccionesJornada { get; set; }
}
An object of class "Prediccion" would contain a list of "itemPrediccion" “Prediccion”类的对象将包含“itemPrediccion”列表
This is the json object that I want to parse to a "Prediccion" object
{
"IdUsuario" : "user1",
"Jornada" : "1",
"PrediccionesJornada" : [
{
"ClavePartido" : "AP2019J1P1",
"Ganador": "Morelia",
"EsFavorito": "false"
},
{
"ClavePartido" : "AP2019J1P2",
"Ganador": "Chivas",
"EsFavorito": "false"
},
{
"ClavePartido" : "AP2019J1P3",
"Ganador": "Atlas",
"EsFavorito": "true"
}
]
}
This is how I´m trying to deserialize这就是我试图反序列化的方式
string requestBody = await new StreamReader(req.Body).ReadToEndAsync();
dynamic data = JsonConvert.DeserializeObject(requestBody);
Prediccion prediccionUsuario = new Prediccion {
IdUsuario = data.IdUsuario,
Jornada = data.Jornada,
PrediccionesJornada = data.PrediccionesJornada
};
Throws this error:抛出这个错误:
Cannot implicitly convert type 'Newtonsoft.Json.Linq.JArray' to 'System.Collections.Generic.IEnumerable'.无法将类型“Newtonsoft.Json.Linq.JArray”隐式转换为“System.Collections.Generic.IEnumerable”。 An explicit conversion exists (are you missing a cast?)存在显式转换(您是否缺少演员表?)
您应该能够使用反序列化器的非动态变体:
var result =JsonConvert.DeserializeObject<Prediccion>(requestBody);
