The Model

using System.Collections.Generic;
using UnityEngine;
[System.Serializable]
public class GetPeopleResult
{
    public List<Person> people { get; set; }
    public GetPeopleResult()
    {
       this.people = new List<People>();
    }
    public static GetPeopleResult CreateFromJSON(string jsonString)
    {
        return JsonUtility.FromJson<GetPeopleResult>(jsonString);
    }
}
[System.Serializable]
public class Person
{
    public long id { get; set; }
    public string name { get; set; }
    public string email { get; set; }
    public string displayImageUrl { get; set; }
    public Person()
    {
    }
    public static Person CreateFromJSON(string jsonString)
    {
        return JsonUtility.FromJson<Person>(jsonString);
    }
}
JSON 

{
    "people":
    [{
        "id":1,"name":"John Smith",
        "email":"jsmith@acme.com",
        "displayImageUrl":"http://example.com/"
    }]
 }

的代码
string json = GetPeopleJson(); //This works
GetPeopleResult result = JsonUtility.FromJson<GetPeopleResult>(json);

调用FromJson后，result不为空，但people集合始终为空。

不能在Unity 5.4中使用JsonUtility反序列化JSON.子集合总是空的

调用FromJson后，结果不是null，而是people集合总是空的。

那是因为Unity不支持属性getter和setter。从你想要序列化的所有类中删除{ get; set; }，这应该修复你的空集合。

同时，this.people = new List<People>();应为this.people = new List<Person>(); 

[System.Serializable]
public class GetPeopleResult
{
    public List<Person> people;
    public GetPeopleResult()
    {
       this.people = new List<People>();
    }
    public static GetPeopleResult CreateFromJSON(string jsonString)
    {
        return JsonUtility.FromJson<GetPeopleResult>(jsonString);
    }
}
[System.Serializable]
public class Person
{
    public long id;
    public string name;
    public string email;
    public string displayImageUrl;
    public Person()
    {
    }
    public static Person CreateFromJSON(string jsonString)
    {
        return JsonUtility.FromJson<Person>(jsonString);
    }
}
