具有字符串列表的JSON DeserializeObject [英] JSON DeserializeObject that has a list of strings

问题描述

[
  {
        "Title": "TOY STORY 4",
        "Genre": "COMEDY",
        "Actors": [
            "Tom Hanks",
            "Tim Allen",
            "Annie Potts"
        ],
        "Id": 1
    },
    {
        "Title": "The Matrix",
        "Genre": "Action",
        "Actors": [
            "Keanu Reeves",
            "Laurence Fishburne",
            "Carrie-Anne Moss"
        ],
        "Id": 2
    }
]

我有一个要转换C#对象的JSON字符串:

I have this JSON string that I want to convert C# object :

public class Movies1
{
    public string Title { get; set; }
    public string Genre{ get; set; }
    public List<Actor> Actors { get; set; }
    public int id { get; set; }
}

public class Actor
{
    public string Actors { get; set; }
    public int Id { get; set; }
}

我的反序列化代码:

List<movies> = JsonConvert.DeserializeObject<List<Movies1>>(json);

我遇到以下错误:

"ExceptionMessage":无法将System.String强制转换或转换为 XXXXX.Models.Actor."， "ExceptionType":"System.ArgumentException"， "StackTrace":在Newtonsoft.Json.Utilities.ConvertUtils.EnsureTypeAssignable(Object 值类型 initialType，类型为targetType)\ r \ n，位于Newtonsoft.Json.Utilities.ConvertUtils.ConvertOrCast(Object initialValue，CultureInfo文化，在键入Type targetType)\ r \ n Newtonsoft.Json.Serialization.JsonSerializerInternalReader.EnsureType(JsonReader 读者，对象 值，CultureInfo文化，JsonContract合同，Type targetType)"

"ExceptionMessage": "Could not cast or convert from System.String to XXXXX.Models.Actor.", "ExceptionType": "System.ArgumentException", "StackTrace": " at Newtonsoft.Json.Utilities.ConvertUtils.EnsureTypeAssignable(Object value, Type initialType, Type targetType)\r\n at Newtonsoft.Json.Utilities.ConvertUtils.ConvertOrCast(Object initialValue, CultureInfo culture, Type targetType)\r\n at Newtonsoft.Json.Serialization.JsonSerializerInternalReader.EnsureType(JsonReader reader, Object value, CultureInfo culture, JsonContract contract, Type targetType)"

推荐答案

似乎Actors是一个字符串列表，您需要的是这样的东西:

It seems the Actors is a list of strings, what you need is something like this:

public class Movies1 
{
    public string Title { get; set; } 
    public string GENRE { get; set; } 
    public List<string> Actors { get; set; } 
    public int Id { get; set; } 
}

public class Root    
{
    public List<Movies1> Movies { get; set; } 
}

然后:

Root myDeserializedClass = JsonConvert.DeserializeObject<Root>(myJsonResponse);
