json数据格式
JSON（JavaScript Object Notation, JS对象简谱）是一种轻量级的数据交换格式。它基于 ECMAScript（European Computer Manufacturers Association, 欧洲计算机协会制定的js规范）的一个子集，采用完全独立于编程语言的文本格式来存储和表示数据。简洁和清晰的层次结构使得 JSON 成为理想的数据交换语言。 易于人阅读和编写，同时也易于机器解析和生成，并有效地提升网络传输效率。
JSON 语法
JSON是一个标记符的序列。这套标记符包含六个构造字符、字符串、数字和三个字面名。
JSON是一个序列化的对象或数组。
{"state":true,"message":"成功访问","result":["苏洵","苏轼","苏辙","苏秦","苏代","苏厉"]}
这里写了个通用的格式，key:value类型。可以直接使用，我们为了练习，强行二次json序列化一下。
返回对象
public class SUCCESS { public SUCCESS(string message,object result) { this.state = true; this.message = message; this.result = result; } public Boolean state { get; set; } public string message { get; set; } public object result { get; set; } }
Json序列化
using Newtonsoft.Json; [HttpGet] public Object GetInfo() { List<string> list = new List<string>() { "苏洵", "苏轼", "苏辙", "苏秦", "苏代", "苏厉" }; return JsonConvert.SerializeObject(new SUCCESS("操作成功", list)); }
下面是返回结果
"{\"state\":true,\"message\":\"成功访问\",\"result\":[\"苏洵\",\"苏轼\",\"苏辙\",\"苏秦\",\"苏代\",\"苏厉\"]}"
反序列化:
使用JsonConvert.DeserializeObject(string)进行反序列化
public object GetInfoApi() { HttpClient http = new HttpClient(); Task<string> task = http.GetStringAsync("http://localhost:1246/api/Test/GetInfo"); string result = task.Result; return JsonConvert.DeserializeObject(result); }
如果未反序列化直接输出则是：
反序列化后：
可以看到对应的效果，不过我们不能使用这种带/的json数据，这类是无法正常解析的。
稍微大型一些json格式数据：
