c# - WebClient 使用 JSON 并发送其属性值

Question

我“创建”了一个非常好的在线工具来为我创建一个 C# 类 ( http://json2csharp.com/ )，但现在我需要创建一个使用 JSON 并使用各自的值填充属性的 WebClient。

实际上我已经尝试过制作自己的WebClient，但我不知道如何将他实现到JSON2Csharp生成的代码中。

JSON2CSharp 代码:

 public class UserModel 
 {
    public int communityvisibilitystate { get; set; }
    public int profilestate { get; set; }
    public string personaname { get; set; }
    public int lastlogoff { get; set; }
    public string profileurl { get; set; }
    public string avatar { get; set; }
    public string avatarmedium { get; set; }
    public string avatarfull { get; set; }
    public int personastate { get; set; }
}

public class Response
{
    public List<UserModel> users { get; set; }
}

public class RootObject
{
    public Response response { get; set; }
}

现在，我尝试使用 UserModel 的类来执行此操作:

public class UserModel
{
    public UserModel()
    {
        WebClient request = new WebClient();
        var response = request.DownloadString(url);

        JsonConvert.PopulateObject(response, this);
    }

    ...
}

但没有成功(正如预期的那样)。所以我问:我该怎么做才能使我的 WebClient 与 JSON2Csharp 的代码兼容？

提前致谢。

我的看法:

@model DotaMix.Models.UserModel
@{
   ViewBag.Title = @Model.personaname;
}

问题:标题不可见。

            JsonConvert.PopulateObject(response, this);

        public string avatarmedium { get; set; }
        public string avatarfull { get; set; }
        public int personastate { get; set; }
    }

    public class Response
    {
        public List<UserModel> users { get; set; }

    public class RootObject

        public Response response { get; set; }
    }

首先，请查看此处有关如何执行您想要的操作的完整代码:http://pastebin.com/aQNtjLHs

您获取的 JSON 可以返回超过 1 个玩家。如果你确定它只返回1，你可以这样使用:

Controller :

public ActionResult Index()
{
    WebClient request = new WebClient();
    var url = "http://api.steampowered.com/ISteamUser/GetPlayerSummaries/v0002/?    key=B88B7699C6EACAE138DDB93BED6467EC&steamids=76561198026602449";
    var response = request.DownloadString(url);

    var myObject = new RootObject();

    JsonConvert.PopulateObject(response, myObject);
    //get only the first player     
    return View(myObject.response.players.FirstOrDefault());
}

查看:

@model DotaMix.Models.Player

@Model.personaname

现在，如果该 json 确实返回超过 1 个玩家，您可以这样做:

Controller :

public ActionResult Index()
{

    WebClient request = new WebClient();
    var url = "http://api.steampowered.com/ISteamUser/GetPlayerSummaries/v0002/?key=B88B7699C6EACAE138DDB93BED6467EC&steamids=76561198026602449";
    var response = request.DownloadString(url);
    var myObject = new RootObject();
    JsonConvert.PopulateObject(response, myObject);
    return View(myObject.response);
}

查看:

@model DotaMix.Models.Response

@foreach (var player in Model.players)
{
  <li>@player.personaname</li>
}
