JSON 到 ListView 中的 C#

Question

我想制作应用程序，其中列出了我在 Steam 上的游戏。我得到了 Steam API 密钥，我得到了带有游戏数据的 JSON，但我不知道如何将其发送到我的 ListView 或类似的东西。我试图找到一些教程，我找到了Newtonsoft.JSON，但我仍然遇到错误。JSON 的外观：{   "response":{      "game_count":27,      "games":[         {            "appid":730,            "name":"Counter-Strike: Global Offensive",            "playtime_2weeks":986,            "playtime_forever":30571,            "img_icon_url":"69f7ebe2735c366c65c0b33dae00e12dc40edbe4",            "img_logo_url":"d0595ff02f5c79fd19b06f4d6165c3fda2372820",            "has_community_visible_stats":true,            "playtime_windows_forever":1600,            "playtime_mac_forever":0,            "playtime_linux_forever":0         },         {            "appid":224260,            "name":"No More Room in Hell",            "playtime_forever":0,            "img_icon_url":"684de0d9c5749b5ddd52f120894fd97efd620b1d",            "img_logo_url":"670e9aba35dc53a6eb2bc686d302d357a4939489",            "has_community_visible_stats":true,            "playtime_windows_forever":0,            "playtime_mac_forever":0,            "playtime_linux_forever":0         },         {            "appid":232010,            "name":"Euro Truck Simulator",            "playtime_forever":11,            "img_icon_url":"6b1bb4a4e2b1e0d85ad0b3e2d6d15a0258aa43a0",            "img_logo_url":"fa3886315d9586671506c7149c1e4ecae653ce13",            "has_community_visible_stats":true,            "playtime_windows_forever":0,            "playtime_mac_forever":0,            "playtime_linux_forever":0         }      ]   }}我尝试过这个，但它不起作用。json = wc.DownloadString("http://api.steampowered.com/IPlayerService/GetOwnedGames/v0001/?key=D4718FA8ED43C531523CF79310BE52FE&steamid=76561198440001695&include_appinfo=1");dynamic results = JsonConvert.DeserializeObject(json);var appid = results.appid();我收到错误：$exception {“组件 ”Newtonsoft.Json.Linq.JObject“ 不包含定义 ”appid“.”}Microsoft.CSharp.RuntimeBinder.RuntimeBinderException

应使用 Newtonsoft 的泛型反序列化器方法反序列化此字符串。

尝试创建一个新类：

 public partial class GameResponse

{

    [JsonProperty("response")]

    public Response Response { get; set; }

}

public partial class Response

{

    [JsonProperty("game_count")]

    public long GameCount { get; set; }

    [JsonProperty("games")]

    public Game[] Games { get; set; }

}

public partial class Game

{

    [JsonProperty("appid")]

    public long Appid { get; set; }

    [JsonProperty("name")]

    public string Name { get; set; }

    [JsonProperty("playtime_2weeks", NullValueHandling = NullValueHandling.Ignore)]

    public long? Playtime2Weeks { get; set; }

    [JsonProperty("playtime_forever")]

    public long PlaytimeForever { get; set; }

    [JsonProperty("img_icon_url")]

    public string ImgIconUrl { get; set; }

    [JsonProperty("img_logo_url")]

    public string ImgLogoUrl { get; set; }

    [JsonProperty("has_community_visible_stats")]

    public bool HasCommunityVisibleStats { get; set; }

    [JsonProperty("playtime_windows_forever")]

    public long PlaytimeWindowsForever { get; set; }

    [JsonProperty("playtime_mac_forever")]

    public long PlaytimeMacForever { get; set; }

    [JsonProperty("playtime_linux_forever")]

    public long PlaytimeLinuxForever { get; set; }

}

然后使用：

var json = wc.DownloadString("http://api.steampowered.com/IPlayerService/GetOwnedGames/v0001/?key=D4718FA8ED43C531523CF79310BE52FE&steamid=76561198440001695&include_appinfo=1");

var results = JsonConvert.DeserializeObject<GameResponse>(json);
