Json 字符串反序列化 C#

Question

I have this json 我想反序列化它，以便我可以获得每个对象的值，例如：

"icon_url": "-9a81dlWLwJ2UUGcVs_nsVtzdOEdtWwKGZZLQHTxDZ7I56KU0Zwwo4NUX4oFJZEHLbXH5ApeO4YmlhxYQknCRvCo04DEVlxkKgpouLWzKjhzw8zFdC5K092kl5SClMj3PLXFhGpC_Pp8j-3I4IG7i1Hn_UI-Nmj3ItDGe1BoN1mCr1G4xL_vhMS8tcmcn3JhuihwsHvbzQv3309k3tBw8A",

问题是我可以制作我需要的 class(es)，这样我就可以反序列化 json，因为 json 字符串具有嵌套对象。

Answer 1

我用json2csharp帮我生成了类。经过一些合并和清理，这就是我得到的：

public class InventoryItem
{
    public string id { get; set; }
    public string classid { get; set; }
    public string instanceid { get; set; }
    public string amount { get; set; }
    public int pos { get; set; }
}

public class AppData
{
    public string def_index { get; set; }
    public int? is_itemset_name { get; set; }
    public int? limited { get; set; }
}

public class Description
{
    public string type { get; set; }
    public string value { get; set; }
    public string color { get; set; }
    public AppData app_data { get; set; }
}

public class Action
{
    public string name { get; set; }
    public string link { get; set; }
}

public class Tag
{
    public string internal_name { get; set; }
    public string name { get; set; }
    public string category { get; set; }
    public string category_name { get; set; }
    public string color { get; set; }
}

public class RgDescription
{
    public string appid { get; set; }
    public string classid { get; set; }
    public string instanceid { get; set; }
    public string icon_url { get; set; }
    public string icon_url_large { get; set; }
    public string icon_drag_url { get; set; }
    public string name { get; set; }
    public string market_hash_name { get; set; }
    public string market_name { get; set; }
    public string name_color { get; set; }
    public string background_color { get; set; }
    public string type { get; set; }
    public int tradable { get; set; }
    public int marketable { get; set; }
    public int commodity { get; set; }
    public string market_tradable_restriction { get; set; }
    public List<Description> descriptions { get; set; }
    public List<Action> actions { get; set; }
    public List<Action> market_actions { get; set; }
    public List<Tag> tags { get; set; }
}

public class RootObject
{
    public bool success { get; set; }
    public IDictionary<string, InventoryItem> rgInventory { get; set; }
    public List<object> rgCurrency { get; set; }
    public IDictionary<string, RgDescription> rgDescriptions { get; set; }
    public bool more { get; set; }
    public bool more_start { get; set; }
}

这些似乎工作正常，您可以使用如下代码反序列化和序列化：

var obj = JsonConvert.DeserializeObject<RootObject>(oldString);
Console.WriteLine(obj.rgDescriptions["310776560_302028390"].icon_url); // e.g.
var newString = JsonConvert.SerializeObject(obj,
     new JsonSerializerSettings { NullValueHandling = NullValueHandling.Ignore });
// null value handling is optional, the above makes it a little more like the source string
