Json格式数据转换

1 数据结构定义

[DataContract]
    public class Person
    {
        [DataMember(Order = 0, IsRequired = true)]
        public string Name { get; set; }

        [DataMember(Order = 1)]
        public int Age { get; set; }

        [DataMember(Order = 2)]
        public bool Alive { get; set; }

        [DataMember(Order = 3)]
        public string[] FavoriteFilms { get; set; }

        [DataMember(Order = 4)]
        public Person Child { get; set; }
    }

var p1 = new Person {
    Age = 12,
    Alive = true,
    Name = "lj",
    FavoriteFilms = new[] { "Up", "Avatar" }
};
var p2 = new Person() { Age = 28, Name = "cy", Child = p1 };

 

2 Json 序列化与反序列化接口实现

    class JSON
    {   
        public static T ParseJsonStr<T>(string jsonString)
        {
            using (var ms = new MemoryStream(Encoding.UTF8.GetBytes(jsonString)))
            {
                return (T)new DataContractJsonSerializer(typeof(T)).ReadObject(ms);
            }
        }

        public static string SerializeToJsonStr(object jsonObject)
        {
            using (var ms = new MemoryStream())
            {
                new DataContractJsonSerializer(jsonObject.GetType()).WriteObject(ms, jsonObject);
                return Encoding.UTF8.GetString(ms.ToArray());
            }
        }
    }

 

3  逻辑代码总进行序列化与反序列化Json格式数据

   // 序列化
    var jsonString = JSON.SerializeToJsonStr(new[] { p1, p2 });
    // 反序列化，泛型集合
    JSON.ParseJsonStr<List<Person>>(jsonString);
    // 反序列化，数组            
    JSON.ParseJsonStr<Person[]>(jsonString);
