問題描述

我有這個(gè) 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"
    }
]

我有這些課程:

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; }
}

我正在嘗試使用以下代碼反序列化上述 JSON:

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

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

但我收到此錯(cuò)誤:

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.

推薦答案

您的 json 字符串包含在方括號(hào) ([]) 中，因此它被解釋為數(shù)組而不是單個(gè) RetrieveMultipleResponse 對(duì)象.因此，您需要將其反序列化為 RetrieveMultipleResponse 的類型集合，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);

這篇關(guān)于無法將 JSON 數(shù)組(例如 [1,2,3])反序列化為類型“"，因?yàn)轭愋托枰?JSON 對(duì)象(例如 {“name":“value"})才能正確反序列化的文章就介紹到這了，希望我們推薦的答案對(duì)大家有所幫助，也希望大家多多支持html5模板網(wǎng)！
