使用来自反序列化嵌套Json的数据？

Question

这是我的JSON：

        };
    }

我的代码：

var json = JsonConvert.DeserializeObject<Welcome>(html);
            foreach (var j in json.Data)
            {
                foreach (var v in j.Contacts)
                {
                    Console.WriteLine(v.Emails[0]);

                }
            }

因此，一旦我反序列化了对象，我尝试使用LINQ使用对象从JSON中获取电子邮件地址，我无法导航到那么远，我不确定什么是最好的最干净的方法在反序列化的JSON中导航电子邮件和电话号码。

Answer 1

首先，由于某种原因，您没有为Email数据定义数据模型：

public partial class Contact
{
    // Initial properties

    [JsonProperty("emails")]
    public object[] Emails { get; set; }

    // Additional properties.

让我们在https://jsonutils.com/的帮助下解决这个问题：

public partial class Contact
{
    // Initial properties as before.

    [JsonProperty("emails")]
    public Email[] Emails { get; set; }

    // Other properties as before
}

public class Email
{
    [JsonProperty("email")]
    public string EmailValue { get; set; }

    [JsonProperty("type")]
    public string Type { get; set; }
}

现在，您可以使用SelectMany创建最终列表来迭代所有电子邮件和电话值：

var emails = json
    // Enumerate through all data
    .Data
    // Enumerate through all contacts of all data
    .SelectMany(d => d.Contacts)
    // Enumerate through all emails of all contacts
    .SelectMany(c => c.Emails)
    // Get email value
    .Select(e => e.EmailValue)
    // Materialize as a list.
    .ToList();

并且

var phones = json
    // Enumerate through all data
    .Data
    // Enumerate through all contacts of all data
    .SelectMany(d => d.Contacts)
    // Enumerate through all phones of all contacts
    .SelectMany(c => c.Phones)
    // Get phone number.  But why ever did you choose to call it PurplePhone!?
    .Select(p => p.PurplePhone)
    // Materialize as a list.
    .ToList();

然后，如果你这样做：

Console.WriteLine("Emails: {0}", JsonConvert.SerializeObject(emails));
Console.WriteLine("Phones: {0}", JsonConvert.SerializeObject(phones));

结果是

Emails: ["testemail@testemail.com"]
Phones: ["+15558675309"]
