另一种快速简单的半自动这些步骤的方法是:

take the JSON you want to parse and paste it here: https://app.quicktype.io/ . Change language to C# in the drop down. Update the name in the top left to your class name, it defaults to "Welcome". In visual studio go to Website -> Manage Packages and use NuGet to add Json.Net from Newtonsoft. app.quicktype.io generated serialize methods based on Newtonsoft. Alternatively, you can now use code like: WebClient client = new WebClient(); string myJSON = client.DownloadString("https://URL_FOR_JSON.com/JSON_STUFF"); var myClass = Newtonsoft.Json.JsonConvert.DeserializeObject(myJSON);

您可能不想仅仅将routes_list声明为对象类型。它没有。test属性，所以你不会得到一个很好的对象。在这里，您最好定义一个类或结构，或者使用dynamic关键字。

如果您真的希望这段代码像您所拥有的那样工作，您需要知道DeserializeObject返回的对象是string,object的泛型字典。下面是这样做的代码:

var json_serializer = new JavaScriptSerializer();
var routes_list = (IDictionary<string, object>)json_serializer.DeserializeObject("{ \"test\":\"some data\" }");
Console.WriteLine(routes_list["test"]);

如果你想使用dynamic关键字，你可以在这里阅读如何使用。

如果你声明一个类或结构，你可以调用Deserialize而不是像这样调用DeserializeObject:

class MyProgram {
    struct MyObj {
        public string test { get; set; }
    }

    static void Main(string[] args) {
        var json_serializer = new JavaScriptSerializer();
        MyObj routes_list = json_serializer.Deserialize<MyObj>("{ \"test\":\"some data\" }");
        Console.WriteLine(routes_list.test);

        Console.WriteLine("Done...");
        Console.ReadKey(true);
    }
}

这是一个简单的类，我从各种帖子....拼凑起来它已经测试了大约15分钟，但似乎符合我的目的。它使用JavascriptSerializer来做这项工作，这可以在你的应用程序中引用，使用这篇文章中详细的信息。

下面的代码可以运行在LinqPad测试它:

在LinqPad中右键单击脚本选项卡，并选择“查询” 属性” 在“附加引用”中引用“System.Web.Extensions.dll” 的“附加名称空间导入” “System.Web.Script.Serialization”。

希望能有所帮助!

  string json = @"

  var d = new JsonDeserializer(json);
  d.GetString("glossary.title").Dump();
  d.GetString("glossary.GlossDiv.title").Dump();  
  d.GetString("glossary.GlossDiv.GlossList.GlossEntry.ID").Dump();  
  d.GetInt("glossary.GlossDiv.GlossList.GlossEntry.ItemNumber").Dump();    
  d.GetObject("glossary.GlossDiv.GlossList.GlossEntry.GlossDef").Dump();   
  d.GetObject("glossary.GlossDiv.GlossList.GlossEntry.GlossDef.GlossSeeAlso").Dump(); 
  d.GetObject("Some Path That Doesnt Exist.Or.Another").Dump();   
}


// Define other methods and classes here

public class JsonDeserializer
{
  private IDictionary<string, object> jsonData { get; set; }

  public JsonDeserializer(string json)
  {
    var json_serializer = new JavaScriptSerializer();

    jsonData = (IDictionary<string, object>)json_serializer.DeserializeObject(json);

    int? result = null;

    object o = GetObject(path);
    if (o == null)
    {
      return result;
    }

    if (o is string)

    }
    catch
    {
      // Probably means an invalid path (ie object doesn't exist)
    }

    return result;
  }
}

使用动态对象JavaScriptSerializer。

JavaScriptSerializer serializer = new JavaScriptSerializer(); 
dynamic item = serializer.Deserialize<object>("{ \"test\":\"some data\" }");
string test= item["test"];

//test Result = "some data"

添加这个ddl来引用您的项目:System.Web.Extensions.dll

使用System.Web.Script.Serialization;

public class IdName
{
    public int Id { get; set; }
    public string Name { get; set; }
}


   string jsonStringSingle = "{'Id': 1, 'Name':'Thulasi Ram.S'}".Replace("'", "\"");
   var entity = new JavaScriptSerializer().Deserialize<IdName>(jsonStringSingle);

   string jsonStringCollection = "[{'Id': 2, 'Name':'Thulasi Ram.S'},{'Id': 2, 'Name':'Raja Ram.S'},{'Id': 3, 'Name':'Ram.S'}]".Replace("'", "\"");
   var collection = new JavaScriptSerializer().Deserialize<IEnumerable<IdName>>(jsonStringCollection);
