我正在尝试使用newtonsoft.json反序列化从White Pages Pro api返回的json字符串。一切都运作良好，并且完美无序地反序列化直到我的商业。过去的一切都是我遇到问题的地方。我遇到的错误如下：
WhitePagesTool.jsonPersonComplex'不包含'Name'的定义，也没有扩展方法'Name'接受类型'WhitePagesTool.jsonPersonComplex'的第一个参数（你是否缺少using指令或汇编引用？）
以下所有错误
对以下所有内容也会抛出相同的错误： firstname，middlename，lastname，age_range，gender，street_line_1，street_line_2，city，postal_code，state_code，country_code，纬度，经度，准确度和associated_people
这是我的反序列化类

using Newtonsoft.Json;
namespace WhitePagesTool
{

public string line_type { get; set; }

public bool is_commercial { get; set; }

答案 0 :(得分：1)
你'name'属性不在'jsonPersonComplex'类中，而是在'BelongsTo'类中。
debugOutput("Name: " + jPerson.name); //should be
debugOutput("Name: " + jPerson.belongs_to().FirstOrDefault()?.name); //sorta like this for example.
此外，您的命名约定已关闭。 Newtonsoft将自动为您命名大写，虽然小写应该有效我建议使用c＃标准制作c＃版本。 Newtonsoft将转换以下标准，所以没关系。
我试过这个并且有效
namespace WhitePagesTool
{
class JsonPersonComplex
{
public string Id { get; set; }
public string Phone_number { get; set; }
public bool Is_valid { get; set; }
public string Line_type { get; set; }
public string Carrier { get; set; }
public bool Is_prepaid { get; set; }
public bool Is_commercial { get; set; }
public List<BelongsTo> Belongs_to { get; set; }
//Current_addresses added to address comments below.
public List<CurrentAddress> Current_addresses { get; set; }
}
public class BelongsTo
{
public string Name { get; set; }
public string Firstname { get; set; }
public string Middlename { get; set; }
public string Lastname { get; set; }
public string Age_range { get; set; }
public string Gender { get; set; }
public string Type { get; set; }
}
public class CurrentAddress
{
public string Street_line_1 { get; set; }
public object Street_line_2 { get; set; }
public string City { get; set; }
public string Postal_code { get; set; }
public string State_code { get; set; }
public string Country_code { get; set; }
public LatLong Lat_long { get; set; }
}
public class LatLong
{
public double Latitude { get; set; }
public double Longitude { get; set; }
public string Accuracy { get; set; }
}
public class AssociatedPeople
{
public string Name { get; set; }
public string Firstname { get; set; }
public string Middlename { get; set; }
public string Lastname { get; set; }
public string Relation { get; set; }
}
}
然后是逻辑......
var jPerson = JsonConvert.DeserializeObject<JsonPersonComplex>(jsonString);
debugOutput("Phone ID: " + jPerson.Id.ToString());
debugOutput("Phone Number: " + jPerson.Phone_number.ToString());
debugOutput("Valid Number: " + jPerson.Is_valid);
debugOutput("Line Type: " + jPerson.Line_type);
debugOutput("Carrier: " + jPerson.Carrier);
debugOutput("Prepaid: " + jPerson.Is_prepaid);
debugOutput("Commercial: " + jPerson.Is_commercial);
debugOutput("Name: " + jPerson.Belongs_to.FirstOrDefault().Name); //and so on
//Street_line_1 added to address comments below
debugOutput("Name: " + jPerson.Belongs_to.FirstOrDefault().Street_line_1); //and so on
