Json data conversion, json

Several Methods for json conversion:

Newtonsoft. Json. dll plugin

Reference the dll file in the project.

Json serialization:

String Jsonreslut = JsonConvert. SerializeObject (Entity );

For example:

DataSet ds = schoolbll.GetList(" F_schoolLevel="+Level);        string result = JsonConvert.SerializeObject(ds);        Response.Write(result);        Response.End();

Json deserialization:

String str = "jsonstr ";

Class model = JsonConvert. DeserializeObject <Class> (jsonstr );

For example:

string tasklist = Request.Params["Taskmodel"];        pt.Model.T_Task Taskmodel = JsonConvert.DeserializeObject<pt.Model.T_Task>(tasklist);

 

Json format of string output:

          StringBuilder sbs = new StringBuilder();        sbs.Append("{\"flag\":" + flag + ",\"msg\":\"" + msg + "\"}");        HttpContext.Current.Response.Write(sbs.ToString());        HttpContext.Current.Response.End(); 

Hashtable outputs json to the page:

  public void WriteJSON(Object hs, HttpResponse MyResponse)    {        System.Web.Script.Serialization.JavaScriptSerializer jss = new System.Web.Script.Serialization.JavaScriptSerializer();        StringBuilder json = new StringBuilder();        jss.Serialize(hs, json);        MyResponse.ContentType = "json";        MyResponse.Write(json.ToString());        MyResponse.End();    }
