一段处理json的C#代码

服务器端：

using Newtonsoft.Json;
using Newtonsoft.Json.Linq;

public ActionResult GetGatherData()
{
  IList<M_Gather> list = gatherpolygonService.GetAll();

  JArray jarr = new JArray();
  foreach (var g in list)
  {
    jarr.Add(new JObject()
    {
      new JProperty("ID",g.GATHERID),
      new JProperty("POINTNAME",g.POINTNAME),
      new JProperty("DEVICEID",g.DEVICEID),
    });
  }
  JObject jobj = new JObject()
  {
    new JProperty("totalCount",getall.Count()),
    new JProperty("topics",jarr)
  };

  return Content(JsonConvert.SerializeObject(jobj), "application/json");
}

得到的json如下：

{
totalCount:10,
topics:[
{ID:"","POINTNAME":"","DEVICEID":""},...
]
}
