JSON在AJAX架构得到广泛应用，是一种有应用前途的数据格式。
问题两个：
（1）在前台应用JSON数据非常方便，但是在后台，比如如下JSON数据
[{"ID":"3","Order":"9"},{"ID":"1",Order":"6"}，{"ID":"2",Order":"8"}]
希望在后台基于ID的大小进行排序，得到如下JSON数据
[{"ID":"1","Order":"6"},{"ID":"2",Order":"8"}，{"ID":"3",Order":"9"}]
有没有高效的实现代码或方法
（2）希望大家能给出后台操作其他JSON格式数据的代码，越多越好了，大家多交流；
愿大家上网开心，工作顺利。。。
------解决方案--------------------------------------------------------
定义实体类
static T Deserialize <T>(string json)
{
T obj = Activator.CreateInstance <T>();
using (MemoryStream ms =
new MemoryStream(Encoding.UTF8.GetBytes(json)))
{
System.Runtime.Serialization.Json.DataContractJsonSerializer serializer =
new System.Runtime.Serialization.Json.DataContractJsonSerializer(obj.GetType());
return (T)serializer.ReadObject(ms);
}
}
再排序
------解决方案--------------------------------------------------------
- C# code
//引用using System.IO;using System.Runtime.Serialization;using System.Runtime.Serialization.Json;
------解决方案--------------------------------------------------------
- C# code
//最后改了下using System;using System.Collections.Generic;using System.Linq;using System.Text;using System.IO;using System.Runtime.Serialization;using System.Runtime.Serialization.Json;namespace ConsoleApplication1{ [DataContract] public sealed class FooDef { [DataMember(Name = "ID", IsRequired = true)] public string ID { get; set; } [DataMember(Name = "Order", IsRequired = true)] public string Order { get; set; } } class Program { static void Main(string[] args) { string bar = "[{\"ID\":\"3\",\"Order\":\"9\"},{\"ID\":\"1\",\"Order\":\"6\"},{\"ID\":\"2\",\"Order\":\"8\"}]"; List<FooDef> newEntities = Deserialize<FooDef>(bar); var s = from l in newEntities orderby l.ID select l; } static List<T> Deserialize<T>(string str) { DataContractJsonSerializer json = new DataContractJsonSerializer(typeof(List<T>)); using (MemoryStream stream = new MemoryStream(Encoding.UTF8.GetBytes(str))) { List<T> entities = (List<T>)json.ReadObject(stream); stream.Close(); return entities; } } }}
