讀取json

//UserInfo.json

[
	{"id":"1","name":"葉良辰","age": "20"},
	{"id":"2","name":"趙日天","age": "25"}
]

 

            JsonData jsonData = JsonMapper.ToObject(File.ReadAllText("UserInfo.json"));
            foreach (JsonData temp in jsonData)
            {
　　　　      string id=temp["id"].ToString();
             string name = temp["name"].ToString();
             string age = temp["age"].ToString();
             Console.WriteLine("id:"+id+" name:"+name+" age:"+age);
            }
            Console.ReadLine();

    class UserInfo
    {
        public string id { get; set; }
        public string name { get; set; }
        public string age { get; set; }
    }

上面的方法其實是比較麻煩的下面介紹 可以直接利用泛型直接返回集合

           //Json的鍵必須和類的屬性或欄位匹配區分大小寫
         UserInfo[] jsonData = JsonMapper.ToObject<UserInfo[]>(File.ReadAllText("UserInfo.json"));

            foreach (UserInfo temp in jsonData)
            {
                Console.WriteLine(temp.id+temp.name+temp.age);
            }
            Console.ReadLine();
