问题描述

我有这个 JSON:

[
    {
        "Attributes": [
            {
                "Key": "Name",
                "Value": {
                    "Value": "Acc 1",
                    "Values": [
                        "Acc 1"
                    ]
                }
            },
            {
                "Key": "Id",
                "Value": {
                    "Value": "1",
                    "Values": [
                        "1"
                    ]
                }
            }
        ],
        "Name": "account",
        "Id": "1"
    },
    {
        "Attributes": [
            {
                "Key": "Name",
                "Value": {
                    "Value": "Acc 2",
                    "Values": [
                        "Acc 2"
                    ]
                }
            },
            {
                "Key": "Id",
                "Value": {
                    "Value": "2",
                    "Values": [
                        "2"
                    ]
                }
            }
        ],
        "Name": "account",
        "Id": "2"
    },
    {
        "Attributes": [
            {
                "Key": "Name",
                "Value": {
                    "Value": "Acc 3",
                    "Values": [
                        "Acc 3"
                    ]
                }
            },
            {
                "Key": "Id",
                "Value": {
                    "Value": "3",
                    "Values": [
                        "3"
                    ]
                }
            }
        ],
        "Name": "account",
        "Id": "2"
    }
]

我有这些课程:

public class RetrieveMultipleResponse
{
    public List<Attribute> Attributes { get; set; }
    public string Name { get; set; }
    public string Id { get; set; }
}

public class Value
{
    [JsonProperty("Value")]
    public string value { get; set; }
    public List<string> Values { get; set; }
}

public class Attribute
{
    public string Key { get; set; }
    public Value Value { get; set; }
}

我正在尝试使用以下代码反序列化上述 JSON:

I am trying to deserialize the above JSON using the code below:

var objResponse1 = JsonConvert.DeserializeObject<RetrieveMultipleResponse>(JsonStr);

但我收到此错误:

无法将当前 JSON 数组(例如 [1,2,3])反序列化为类型'test.Model.RetrieveMultipleResponse' 因为该类型需要 JSON对象(例如 {"name":"value"})正确反序列化.要解决这个问题错误要么将 JSON 更改为 JSON 对象(例如 {"name":"value"})或将反序列化类型更改为数组或实现的类型一个集合接口(例如 ICollection、IList)，比如 List 可以从 JSON 数组反序列化.JsonArrayAttribute 也可以添加到类型以强制它从 JSON 数组反序列化.小路''，第 1 行，位置 1.

Cannot deserialize the current JSON array (e.g. [1,2,3]) into type 'test.Model.RetrieveMultipleResponse' because the type requires a JSON object (e.g. {"name":"value"}) to deserialize correctly. To fix this error either change the JSON to a JSON object (e.g. {"name":"value"}) or change the deserialized type to an array or a type that implements a collection interface (e.g. ICollection, IList) like List that can be deserialized from a JSON array. JsonArrayAttribute can also be added to the type to force it to deserialize from a JSON array. Path '', line 1, position 1.

推荐答案

您的 json 字符串包含在方括号 ([]) 中，因此它被解释为数组而不是单个 RetrieveMultipleResponse 对象.因此，您需要将其反序列化为 RetrieveMultipleResponse 的类型集合，例如:

Your json string is wrapped within square brackets ([]), hence it is interpreted as array instead of single RetrieveMultipleResponse object. Therefore, you need to deserialize it to type collection of RetrieveMultipleResponse, for example :

var objResponse1 = 
    JsonConvert.DeserializeObject<List<RetrieveMultipleResponse>>(JsonStr);
