怎么把json转成a的实体对象?

4个回答

你这个类实体和json字符串对不上,应该是

 public class a{
public string name{get; set;};
public string value{get; set;};

}

用JSON.NET序列化下就行了


       List<a> arr= Newtonsoft.Json.JsonConvert.DeserializeObject<List<a>>("JSON字符串");

{name:\'name\',sex:\'sex\'}
利用jsonobject转换或者用反射转

JObject jo = (JObject)JsonConvert.DeserializeObject(result);

                result = jo["result"].ToString();

                                    在一一赋值

如何将具有动态字段的JSON对象映射到Go结构

<div class="post-text" itemprop="text"> <p>I am developing a website using Go and connecting it to Elastic Search. In Elastic Search I can have dynamic fields for index types.
