例如，我想获得页面的数量从喜欢一个页面上的JSON响应和显示只是喜欢的数量。

任何帮助很多AP preciated：）

  //
    // GET：/ Facebook的/    公众的ActionResult指数（）
    {
        VAR JSON =新的WebClient（）DownloadString（https://graph.facebook.com/google）;
        JsonConvert.DeserializeObject＆LT; RootObject＆GT;（JSON）;        返回视图（）;
    }    公共类所属分类
    {
        公共字符串ID {搞定;组; }
        公共字符串名称{;组; }
    }    公共类位置
    {
        公共字符串街{搞定;组; }
        公共字符串城市{搞定;组; }
        公共字符串状态{搞定;组; }
        公共字符串国{搞定;组; }
        公共字符串拉链{搞定;组; }
        公共双纬度{搞定;组; }
        公共双经度{搞定;组; }
    }    公共类封面
    {
        公共字符串cover_id {搞定;组; }
        公共字符串源{搞定;组; }
        公众诠释offset_y {搞定;组; }
        公众诠释offset_x {搞定;组; }
    }    公共类RootObject
    {
        关于{获得公共字符串;组; }
        公共字符串奖{搞定;组; }
        公共字符串类{搞定;组; }
        公开名单＆LT;所属分类＆GT; category_list {搞定;组; }
        公众诠释签入{搞定;组; }
        公共字符串COMPANY_OVERVIEW {搞定;组; }
        公共字符串描述{搞定;组; }
        公共字符串创建{搞定;组; }
        公共BOOL is_published {搞定;组; }
        公共场所的位置{搞定;组; }
        公共字符串任务{搞定;组; }
        公共字符串电话{搞定;组; }
        公共字符串产品{搞定;组; }
        公众诠释talking_about_count {搞定;组; }
        公共字符串的用户名{获得;组; }
        公共字符串网站{搞定;组; }
        公众诠释were_here_count {搞定;组; }
        公共字符串ID {搞定;组; }
        公共字符串名称{;组; }
        公共字符串链接{搞定;组; }
        公众诠释喜欢{搞定;组; }
        公共盖盖{搞定;组; }
    }
}
}
 

解决方案

您应该采取行动的对象传递给视图：

 公众的ActionResult指数（）
{
    VAR JSON =新的WebClient（）DownloadString（https://graph.facebook.com/google）;
    VAR根= JsonConvert.DeserializeObject＆LT; RootObject＆GT;（JSON）;    返回视图（根）;
}
 

，然后在您的视图可以显示任何你想要的属性：

  @Model RootObject
＆LT; HTML和GT;
    ＆LT; HEAD＆GT;
        ＆LT;标题＆GT;显示性能＆LT; /标题＆GT;
    ＆LT; /头＆GT;
    ＆LT;身体GT;
        @ Model.likes喜欢。
    ＆LT; /身体GT;
＆LT; / HTML＆GT;
 

这是如果你使用的剃刀语法。

First of all, I'm new to MVC.

I want to display the properties of the JSON response in a html view.

For example, i want to get the number of page likes from the JSON response and display just the number of likes on a page.

Any help is much appreciated :)

    //
    // GET: /Facebook/

    public ActionResult Index()
    {
        var json = new WebClient().DownloadString("https://graph.facebook.com/google");
        JsonConvert.DeserializeObject<RootObject>(json);

        return view();
    }

    public class CategoryList
    {
        public string id { get; set; }
        public string name { get; set; }
    }

    public class Location
    {
        public string street { get; set; }
        public string city { get; set; }
        public string state { get; set; }
        public string country { get; set; }
        public string zip { get; set; }
        public double latitude { get; set; }
        public double longitude { get; set; }
    }

    public class Cover
    {
        public string cover_id { get; set; }
        public string source { get; set; }
        public int offset_y { get; set; }
        public int offset_x { get; set; }
    }

    public class RootObject
    {
        public string about { get; set; }
        public string awards { get; set; }
        public string category { get; set; }
        public List<CategoryList> category_list { get; set; }
        public int checkins { get; set; }
        public string company_overview { get; set; }
        public string description { get; set; }
        public string founded { get; set; }
        public bool is_published { get; set; }
        public Location location { get; set; }
        public string mission { get; set; }
        public string phone { get; set; }
        public string products { get; set; }
        public int talking_about_count { get; set; }
        public string username { get; set; }
        public string website { get; set; }
        public int were_here_count { get; set; }
        public string id { get; set; }
        public string name { get; set; }
        public string link { get; set; }
        public int likes { get; set; }
        public Cover cover { get; set; }
    }
}
}

解决方案

Your action should pass the object to the view:

public ActionResult Index()
{
    var json = new WebClient().DownloadString("https://graph.facebook.com/google");
    var root=JsonConvert.DeserializeObject<RootObject>(json);

    return view(root);
}

and then in your view you can show whichever property you want:

@Model RootObject
<html>
    <head>
        <title>Showing properties</title>
    </head>
    <body>
        @Model.likes likes.
    </body>
</html>

This is if you use the Razor syntax.
