如何将 JSON 嵌套对象数组反序列化为 C# 对象

Question

我被这个问题难住了，无法继续。我也不是很有经验，因此将不胜感激您的帮助。我正在使用返回以下数据的 API：

{"userdata":[{"IdCustomer":"4","IdShop_group":"1","IdShop":"2","IdGender":"1","IdDefault_group":"3","IdLang":"2","Company":null,"Firstname":"John","Lastname":"Doe","Email":"[e-mail]","NumpadPIN":"99999999","Birthday":"1991-12-24","Newsletter":"0","Optin":"0","Active":"1","Date_add":"2019-04-09 07:37:29","Date_upd":"2019-07-17 11:38:25"}]}

我使用“json2csharp”设置了以下课程

public class Userdata

{

    public string IdCustomer { get; set; }

    public string IdShop_group { get; set; }

    public string IdShop { get; set; }

    public string IdGender { get; set; }

    public string IdDefault_group { get; set; }

    public string IdLang { get; set; }

    public object Company { get; set; }

    public string Firstname { get; set; }

    public string Lastname { get; set; }

    public string Email { get; set; }

    public string Birthday { get; set; }

    public string Newsletter { get; set; }

    public string Optin { get; set; }

    public string Active { get; set; }

    public string Date_add { get; set; }

    public string Date_upd { get; set; }

}

    public class User

{

    public IList<Userdata> userdata { get; set; }

}

这是我提取数据的方法

//changed the url for this question

    var URL = "https://dummyvalue.com";

                    var request = new HttpRequestMessage();

                    request.RequestUri = new Uri(URL);

                    request.Method = HttpMethod.Get;

                    request.Headers.Add("Accept", "application/json");

                    var client = new HttpClient();

                    HttpResponseMessage response = await client.SendAsync(request);

                    }

我的问题是如何分配/使用已反序列化的值？我想访问作为类对象详细信息的值，例如。

var name = userObject.Firstname;

var surname = userObject.Lastname;

我读了很多书并尝试了不同的方法，但我一定错过了一些东西..

Answer 1

您需要使用 RootObjectvar response = JsonConvert.DeserializeObject<RootObject>(json);foreach(var userObject in response.userdata){&nbsp; &nbsp; //use here userObject.Firstname;}
