Question

我有一个问题，即反序列化Json对象：

Newtonsoft.Json.JsonSerializationException：无法将当前JSON对象（例如{“name”：“value”}）反序列化为类型'System.Collections.Generic.List`1 [xxx.Models.FollowerResponseModel]'，因为类型需要一个JSON数组（例如[1,2,3]）才能正确反序列化。要修复此错误，请将JSON更改为JSON数组（例如[1,2,3]）或更改反序列化类型，使其成为普通的.NET类型（例如，不是像整数这样的基本类型，而不是类似的集合类型可以从JSON对象反序列化的数组或List。 JsonObjectAttribute也可以添加到类型中以强制它从JSON对象反序列化。路径'用户'，第2行，第10位。

{"result":{"status":200,"response":{"data":{"users":[
{"uin":223,"login":"tttttt","uin_follows":true,"follow_of_uin":false,"blocked":false},
{"uin":225,"login":"hggjhjj","uin_follows":false,"follow_of_uin":true,"blocked":true},
{"uin":226,"login":"testestefy","uin_follows":false,"follow_of_uin":false,"blocked":true}
],"version":"1"}}}}

My FollowersResponModel

public class FollowerResponseModel
{
    [JsonProperty("users")]
    public List<UserFollowersModel> Users { get; set; }

    [JsonProperty("version")]
    public int Version { get; set; }
}

public class UserFollowersModel
{
    [JsonProperty("uin")]
    public int Uin { get; set; }

    [JsonProperty("login")]
    public string Login { get; set; }

    [JsonProperty("uin_follows")]
    public bool UinFollows { get; set; }

    [JsonProperty("follow_of_uin")]
    public bool FollowOfUin { get; set; }

    [JsonProperty("blocked")]
    public bool Blocked { get; set; }
}

我的FollowersModel类应该如何？

我的方法GetFollowers ...

public async Task<List<FollowerModel>> GetFollowersBlockedList(int version)
{
    var request = CreateHttpRequest(string.Format(FOLLOWERS_BLOCKED_URL), HttpMethod.Get, true);

    var response = await CallRequestAsync(request, HttpContentType.ApplicationJson);

    if (response == null) return null;

    var stream = await response.Content.ReadAsStreamAsync();
    var content = Tools.ConvertStreamToString(stream);

    if (string.IsNullOrEmpty(content)) return null;

    var responseModel = JsonConvert.DeserializeObject<ResponseModel>(content);

    if (response.IsSuccessStatusCode)
    {
        _log.MessageInDebug("OK");

        var data = responseModel.Result.Response.Data.ToString();

        var list = JsonConvert.DeserializeObject<List<FollowerResponseModel>>(data);

        if (list == null || list.Count() == 0) return null;

        return list.Select(x => new FollowerModel(x)).ToList();
    }

    return null;
}

FollowerResponseModel已包含List<User>，因此您无需反序列化List<FollowerResponseModel>

var follow = JsonConvert.DeserializeObject<FollowerResponseModel>(data);

if (follow.Users == null || follow.Users.Count() == 0) return null;
