C# 对象与JSON串互相转换

DoNet2.0 需要借助于Newtonsoft.Json.dll

代码
   
     
using System;
using System.IO;
using System.Text;
using Newtonsoft.Json;

namespace OfflineAcceptControl.UCTools
{
public class JsonTools
{
// 从一个对象信息生成Json串
public static string ObjectToJson( object obj)
{
return JavaScriptConvert.SerializeObject(obj);
}
// 从一个Json串生成对象信息
public static object JsonToObject( string jsonString, object obj)
{
return JavaScriptConvert.DeserializeObject(jsonString, obj.GetType());
}
}
}

 

 

 

 

Donet3.5自带了DLL处理json串

注意引用:System.Runtime.Serialization,System.ServiceModel.Web

代码
    
      
using System;
using System.Collections.Generic;
using System.IO;
using System.Linq;
using System.Text;
using System.Runtime.Serialization;
using System.Runtime.Serialization.Json;

namespace CrjIIOfflineAccept.CrjIITools
{
public class JsonTools
{
// 从一个对象信息生成Json串
public static string ObjectToJson( object obj)
{
DataContractJsonSerializer serializer
= new DataContractJsonSerializer(obj.GetType());
MemoryStream stream
= new MemoryStream();
serializer.WriteObject(stream, obj);
byte [] dataBytes = new byte [stream.Length];
stream.Position
= 0 ;
stream.Read(dataBytes,
0 , ( int )stream.Length);
return Encoding.UTF8.GetString(dataBytes);
}
// 从一个Json串生成对象信息
public static object JsonToObject( string jsonString, object obj)
{
DataContractJsonSerializer serializer
= new DataContractJsonSerializer(obj.GetType());
MemoryStream mStream
= new MemoryStream(Encoding.UTF8.GetBytes(jsonString));
return serializer.ReadObject(mStream);
}
}
}
