c# 對象 與 Json串 轉換

下面的對象與json串之間的轉換在framework2.0下測試通過
注意：需要下載 Newtonsoft.Json.dll，並引用到項目中
using System;
using System.IO;
using System.Text;
using Newtonsoft.Json;
 
namespaceOfflineAcceptControl.UCTools
{
    publicclass JsonTools
    {
        // 從一個對象信息生成Json串
        publicstatic stringObjectToJson(objectobj)
        {
           returnJavaScriptConvert.SerializeObject(obj);
        }
        // 從一個Json串生成對象信息
        publicstatic objectJsonToObject(stringjsonString, objectobj)
        {
           returnJavaScriptConvert.DeserializeObject(jsonString, obj.GetType());
        }
    }
}
 
 
下面的對象與json串之間的轉換在framework3.5下測試通過
注意引用：System.Runtime.Serialization，System.ServiceModel.Web
usingSystem;
usingSystem.Collections.Generic;
usingSystem.IO;
usingSystem.Linq;
usingSystem.Text;
usingSystem.Runtime.Serialization;
usingSystem.Runtime.Serialization.Json;
 
namespaceCrjIIOfflineAccept.CrjIITools
{
    publicclass JsonTools
    {
        // 從一個對象信息生成Json串
        publicstatic stringObjectToJson(objectobj)
        {
           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);
           returnEncoding.UTF8.GetString(dataBytes);
        }
        // 從一個Json串生成對象信息
        publicstatic objectJsonToObject(stringjsonString, objectobj)
        {
           DataContractJsonSerializer serializer =new DataContractJsonSerializer(obj.GetType());
           MemoryStream mStream =new MemoryStream(Encoding.UTF8.GetBytes(jsonString));
           returnserializer.ReadObject(mStream);
        }
    }
}
