请教一个在.NET一般处理程序ashx中序列化List<>为Json的一个【小问题—嵌套】

[TianYi3G2013]

【一般处理程序的代码】

public class JsonHandler : IHttpHandler

    {

        busers objbusers = new busers();

 

        public void ProcessRequest(HttpContext context)

        {

            List<easyUI.Model.musers> userList=new List<easyUI.Model.musers>();

            userList=objbusers.GetModelList("");        //获取一个类集合；

 

            context.Response.ContentType = "application/json";

            context.Response.Cache.SetCacheability(HttpCacheability.NoCache);   //禁止浏览器的缓存作用；        

            System.Type type =userList.GetType();  //获取userList的类型

 

            //序列化：

            System.Runtime.Serialization.Json.DataContractJsonSerializer serializer = new System.Runtime.Serialization.Json.DataContractJsonSerializer(type);     

            serializer.WriteObject(context.Response.OutputStream, userList); 

        }

 

        public bool IsReusable

        {

            get

            {

                return false;

            }

        }

    }

//以上代码响应给浏览器的Json为：




但我真正上要的格式是：



-------------------------------------------------------------------------
在PHP中可以这样转换的：

1.           $rs = mysql_query('select * from users');
2.           $result = array();
3.           while($row = mysql_fetch_object($rs)){
4.               array_push($result, $row);
5.           }
6.            
7.           echo json_encode($result);

-------------------------------------------------------------------------
如果熟练Json序列化的，做到这个，应该是容易的事情，对么？小弟刚接触Json，所以不知道怎样处理好，特发帖子请教一下！望有心人指导一下谢谢！

var data = new Hashtable(); data["rows"] = userlist; data["total"] = userlist.Count; Serialize(data);

引用 1 楼 KarasCanvas 的回复:

var data = new Hashtable(); data["rows"] = userlist; data["total"] = userlist.Count; Serialize(data);

 public void ProcessRequest(HttpContext context)
        {
            List<easyUI.Model.musers> userList=new List<easyUI.Model.musers>();
            userList=objbusers.GetModelList("");        //获取一个类集合；

            var data = new System.Collections.Hashtable();
            data["rows"] = userList;
            data["total"] = userList.Count;  //获取行数

            context.Response.ContentType = "application/json";
            context.Response.Cache.SetCacheability(HttpCacheability.NoCache);   //禁止浏览器的缓存作用；        
            System.Type type =data.GetType();  //获取userList的类型

            //序列化：
            System.Runtime.Serialization.Json.DataContractJsonSerializer serializer = new System.Runtime.Serialization.Json.DataContractJsonSerializer(type);     
            serializer.WriteObject(context.Response.OutputStream, data);
        }

【要怎样修改呢？】我这样改，运行就报错了： Type 'System.Collections.Generic.List`1[[easyUI.Model.musers, easyUI.Model, Version=2.0.0.0, Culture=neutral, PublicKeyToken=null]]' with data contract name 'ArrayOfmusers:http://schemas.datacontract.org/2004/07/easyUI.Model' is not expected. Consider using a DataContractResolver or add any types not known statically to the list of known types - for example, by using the KnownTypeAttribute attribute or by adding them to the list of known types passed to DataContractSerializer.

改用json.net来序列化吧

嗯嗯，能不能先解决上面这个问题呢？

[种草德鲁伊]

用json.net就没上面的问题了

怎么调用？怎么同浏览器输出？

public void ProcessRequest(HttpContext context)
        {
            List<easyUI.Model.musers> userList=new List<easyUI.Model.musers>();
            userList=objbusers.GetModelList("");        //获取一个类集合；


            var data = new System.Collections.Hashtable();
            data["rows"] = userList;
            data["total"] = userList.Count;

            //Newtonsoft.Json.Serialization.  //

            Serialize(data);  //找到到。。。命名空间已经引用Newtonsoft.Json.Serialization.  

            //var data = new System.Collections.Hashtable();
            //data["rows"] = userList;
            //data["total"] = userList.Count;  //获取行数

            //context.Response.ContentType = "application/json";
            //context.Response.Cache.SetCacheability(HttpCacheability.NoCache);   //禁止浏览器的缓存作用；        
            //System.Type type =data.GetType();  //获取userList的类型

            ////序列化：
            //System.Runtime.Serialization.Json.DataContractJsonSerializer serializer = new System.Runtime.Serialization.Json.DataContractJsonSerializer(type);    
 

            //serializer.WriteObject(context.Response.OutputStream, data);
        }

这样可以了。。谢谢！ public void ProcessRequest(HttpContext context) { List<easyUI.Model.musers> userList=new List<easyUI.Model.musers>(); userList=objbusers.GetModelList(""); //获取一个类集合； var data = new System.Collections.Hashtable(); data["rows"] = userList; data["total"] = userList.Count; context.Response.Write(Newtonsoft.Json.JsonConvert.SerializeObject(data));
