在我的小库中,我正在编写一个辅助项目,我正在使用RestSharp从Web API获取Json。对模型类的反序列化对于简单类型可以正常工作,但是在请求时有结果类型未知(或不清楚)的端点。
具体来说,它的GuildWars2 API v1和一个例子就是项目数据。当然,每个项目都有基本属性,并根据查询的项目设置其他值。 例如,武器有一些修饰符等等。
我的想法是为所有基本属性创建一个抽象的Item类,并从该类派生所有现有的子类型添加所需的属性。我的问题是,如何决定要反序列化的子类。我已经阅读过各种涉及向Json字符串添加限定类型名称的方法,但由于我只从API获取数据,因此无法影响我得到的响应。
理想情况下,我总是希望反序列化到基类Item中,反序列化器通过Json字符串中包含的给定属性来确定实际类型。这是否可能?或者有更好的方法来解决这个问题吗?
提前致谢
编辑:这是武器的Json示例:
{
"item_id": "30704",
"name": "Twilight",
"description": "",
"type": "Weapon",
"level": "80",
"rarity": "Legendary",
"vendor_value": "100000",
"icon_file_id": "456031",
"icon_file_signature": "CE3AF0B7B9BB6244726779F5B6A930541BA6C15F",
"game_types": ["Activity", "Dungeon", "Pve", "Wvw"],
"flags": ["HideSuffix", "NoSell", "SoulBindOnUse"],
"restrictions": [],
"weapon": {
"type": "Greatsword",
"damage_type": "Physical",
"min_power": "995",
"max_power": "1100",
"defense": "0",
"infusion_slots": [],
"infix_upgrade": {
"attributes": [
{
"attribute": "Power",
"modifier": "179"
},
{
"attribute": "Power",
"modifier": "179"
}
]
},
"suffix_item_id": "24599"
}
}
这将是一件盔甲:
{
"item_id":"500",
"name":"Carrion Conjurer Chest of Dwayna",
"description":"",
"type":"Armor",
"level":"68",
"rarity":"Rare",
"vendor_value":"257",
"icon_file_id":"61023",
"icon_file_signature":"76CD08463A05730071D400254141B50E570662D3",
"game_types":["Activity", "Dungeon", "Pve", "Wvw"],
"flags":["SoulBindOnUse"],
"restrictions":[],
"armor": {
"type":"Coat",
"weight_class":"Light",
"defense":"221",
"infusion_slots":[],
"infix_upgrade": {
"attributes": [
{
"attribute":"ConditionDamage","modifier":"70"
},
{
"attribute":"Power","modifier":"50"
}
]
},
"suffix_item_id":"24767"
}
}
我想根据属性“类型”的内容反序列化,但我无法弄清楚,这将如何工作= /

您可以使用JObject解析JSON数据,然后可以将其用作关联数组。
string json = @"{
"item_id": "30704",
"name": "Twilight",
"description": "",
"type": "Weapon",
...
}";
JObject o = JObject.Parse(json);
Item item = null;
switch (o["type"])
{
case "Weapon":
item = JsonConvert.DeserializeObject<Weapon>(json);
break;
case "Armor":
item = JsonConvert.DeserializeObject<Armor>(json);
break;
default:
// throw error?
}
然后你会有一个基类:
public class Item
{
public string item_id { get; set; }
public string name { get; set; }
public string description { get; set; }
public string type { get; set; }
...
// List all common properties here
public Item() { }
// It's important to have the public default constructor implemented
// if you intend on overloading it for your own purpose later
}
你的武器课可以这样:
public class Weapon : Item // Weapon extends Item
{
public WeaponDetails weapon { get; set; }
public Weapon() { }
}
和武器细节:
public class WeaponDetails
{
public string type { get; set; }
public string damage_type { get; set; }
public int min_power { get; set; }
public int max_power { get; set; }
...
public WeaponDetails() { }
}
