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);
