JSON反序列化:如何从对象的JSON数组中获取值 [英] JSON Deserialization: How to get values out of a JSON array of objects

问题描述

我已经在C#中成功反序列化了此JSON字符串，但是无法从嵌套在数组中的对象中提取值:

I've successfully deserialized this JSON string in C#, but can't extract the values from the objects nested in the array:

JavaScriptSerializer js = new JavaScriptSerializer();

string json = 
  {"key":"1234","status":"ok","members":
      [{"id":7,"name":"Joe"},
   {"id":2,"name":"Robert"},
   {"id":18,"name":"Tim"}
      ]
   }

var d = js.Deserialize < dynamic > (json);

string _key = d["key"]; // this works

Array _members = d["members"]; // this works, length = 3

但是我很难按名称从对象中提取值，例如，这是不对的，但从本质上来说我想要

But I'm having trouble extracting the values out of the objects by name, e.g, this isn't right, but essentially I want

_members [0] ["name"]或_members [0] .name

_members[0]["name"] or, _members[0].name

我认为反序列化器使数组字典中的对象成为对象，但是我认为我正在清除遗漏的东西...

I think the deserializer makes the objects inside the array dictionaries, but I think I'm clearing missing something...

推荐答案

我建议使用 Json.NET 来完成您的工作正在做.以下代码可以满足您的要求:

I recommend using Json.NET to do what you're doing. The following code does what you want:

    JObject jObject = JObject.Parse(json);
    JToken memberName = jObject["members"].First["name"];
    Console.WriteLine(memberName); // Joe

通过 LINQ to Json .

更新:

    var js = new JavaScriptSerializer();
    var d = js.Deserialize<dynamic>(json);
    Console.WriteLine(d["members"][0]["name"]); // Joe

也可以.
