Question

以下是Postman的JSON结果

{
    "result": [
        {
            "brands": [],
            "services": [],
            "addresses": [],
            "accessPoints": [],
            "Kodu": "100",
            "name": "üeticissdss",
            "taxNumber": "asd",
            "taxOffice": "sada",
            "id": "bfb064f4-0732-43ab-9d94-87f6934258fe",
            "isActive": true
        },
        {
            "brands": [],
            "services": [],
            "addresses": [],
            "accessPoints": [],
            "Kodu": "100",
            "name": "üeticissdss",
            "taxNumber": "asd",
            "taxOffice": "sada",
            "id": "bfb064f4-0732-43ab-9d94-87f69d4258fe",
            "isActive": true
        }
    ],
    "id": 13,
    "exception": null,
    "status": 5,
    "isCanceled": false,
    "isCompleted": true,
    "isCompletedSuccessfully": true,
    "creationOptions": 0,
    "asyncState": null,
    "isFaulted": false
}

我想尝试反序列化json，如下所示：

    [BindProperty]
    public List<Manufacturer> manufacturer { get; set; }
HttpClient httpClient = new HttpClient();
            httpClient.BaseAddress = new Uri(apiParameters.HttpClientBaseAddress);
            httpClient.DefaultRequestHeaders.Accept.Clear();
            httpClient.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue(apiParameters.DefaultRequestHeadersJson));
            customIndexModel.ApiResponseMessage = await httpClient.GetAsync(apiParameters.HttpClientBaseAddress);
            if (customIndexModel.ApiResponseMessage.IsSuccessStatusCode)
            {
                var jsonAsString = customIndexModel.ApiResponseMessage.Content.ReadAsStringAsync().Result;
                manufacturer = JsonConvert.DeserializeObject<List<Manufacturer>>(jsonAsString);                    
            }

错误消息：

无法将当前JSON对象（例如{“name”：“value”}）反序列化为类型'System.Collections.Generic.List`1 [Q.Entity.Manufacturer.Manufacturer]'，因为该类型需要JSON数组（例如[1,2,3]）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'结果'，第1行，第10位。

看起来我想念一些东西，但我无法弄明白。你能帮帮我吗？

这是从http://json2csharp.com/

生成的de c＃类

public class Result
    {
        public List<object> brands { get; set; }
        public List<object> services { get; set; }
        public List<object> addresses { get; set; }
        public List<object> accessPoints { get; set; }
        public string Kodu { get; set; }
        public string name { get; set; }
        public string taxNumber { get; set; }
        public string taxOffice { get; set; }
        public string id { get; set; }
        public bool isActive { get; set; }
    }

    public class RootObject
    {
        public List<Result> result { get; set; }
        public int id { get; set; }
        public object exception { get; set; }
        public int status { get; set; }
        public bool isCanceled { get; set; }
        public bool isCompleted { get; set; }
        public bool isCompletedSuccessfully { get; set; }
        public int creationOptions { get; set; }
        public object asyncState { get; set; }
        public bool isFaulted { get; set; }
    }

我将JSON反序列化为dataList

[BindProperty]
public RootObject dataList { get; set; }

var jsonAsString = customIndexModel.ApiResponseMessage.Content.ReadAsStringAsync().Result;
dataList = JsonConvert.DeserializeObject<RootObject>(jsonAsString);

在JSOn反序列化后，我可以在Razor页面中使用结果，如下所示

@foreach (var item in Model.dataList.result)
{
++rowNumber;
<tr>
<td>@item.code</td>
<td>@item.name</td>
<td>@item.isActive</td>
</

谢谢。
