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":""},...
]
}
