试试这个:

  var units = new { Name = "Phone", Color= "White" };
    var jsonResponse = JsonConvert.DeserializeAnonymousType(json, units);

试试这种方法!

JSON的例子:

[{
    "id": 140,
    "group": 1,
    "text": "xxx",
    "creation_date": 123456,
    "created_by": "xxx@gmail.co",
    "tags": ["xxxxx"]
  }, {
    "id": 141,
    "group": 1,
    "text": "xxxx",
    "creation_date": 123456,
    "created_by": "xxx@gmail.com",
    "tags": ["xxxxx"]
}]

c#代码:

var jsonString = (File.ReadAllText(Path.Combine(Directory.GetCurrentDirectory(),"delete_result.json")));
var objects = JsonConvert.DeserializeObject<dynamic>(jsonString);
foreach(var o in objects)
{
    Console.WriteLine($"{o.id.ToString()}");
}

另一种选择是“将JSON粘贴为类”，这样就可以快速轻松地反序列化。

只需复制整个JSON 在Visual Studio中:点击编辑→特殊粘贴→将JSON作为类粘贴

这里有一个更好的解释…“将JSON粘贴为类”NET和Web工具2012.2 RC

为此，我将使用JSON。NET对JSON流进行低级解析，然后从ExpandoObject类的实例构建对象层次结构。

如果你喜欢依赖System.Web.Helpers程序集，那么你可以使用Json类:

dynamic data = Json.Decode(json);

它作为。net 4框架的附加下载包含在MVC框架中。如果有用的话，一定要给弗拉德点赞!但是，如果您不能假定客户机环境包含这个DLL，那么请继续阅读。

这里建议使用另一种反序列化方法。我稍微修改了代码，以修复一个错误，并适合我的编码风格。所有你需要的是这段代码和从你的项目中引用System.Web.Extensions:

你可以这样使用它:

string json = ...;

var serializer = new JavaScriptSerializer();
serializer.RegisterConverters(new[] { new DynamicJsonConverter() });

dynamic obj = serializer.Deserialize(json, typeof(object));

给定一个JSON字符串:

{
  "Items":[
    { "Name":"Apple", "Price":12.3 },
    { "Name":"Grape", "Price":3.21 }
  ],
  "Date":"21/11/2010"
}

下面的代码将在运行时工作:

dynamic data = serializer.Deserialize(json, typeof(object));

data.Date; // "21/11/2010"
data.Items.Count; // 2
data.Items[0].Name; // "Apple"
data.Items[0].Price; // 12.3 (as a decimal)
data.Items[1].Name; // "Grape"
data.Items[1].Price; // 3.21 (as a decimal)

你想要的DynamicJSONObject对象包含在ASP. web . helpers .dll中。NET Web Pages包，它是WebMatrix的一部分。
