c# - 如何使用 JSON.NET 反序列化并保留父对象

Question

我有一些像这样的 JSON:

{
  "companyName": "Software Inc.",
  "employees": [
    {
      "employeeName": "Sally"
    },
    {
      "employeeName": "Jimmy"
    }
  ]
}

我想将它反序列化为:

public class Company
{
  public string companyName { get; set; }
  public IList<Employee> employees { get; set; }
}

public class Employee
{
  public string employeeName { get; set; }
  public Company employer { get; set; }
}

如何让 JSON.NET 设置“雇主”引用？我尝试使用 CustomCreationConverter，但是 public override object ReadJson(JsonReader reader, Type objectType, object existingValue, JsonSerializer serializer) 方法不包含对当前的任何引用父对象。

如果您在反序列化过程中尝试这样做，那只会让您头疼。在反序列化之后执行该任务会容易得多。做这样的事情:

var company = //deserialized value

foreach (var employee in company.employees)
{
    employee.employer = company;
}

或者一行代码，如果你更喜欢这样的语法:

company.employees.ForEach(e => e.employer = company);
