C#服务端：

代码如下:

public JsonResult GetData()
        {
            Random ro = new Random();

List<int> vListInt = new List<int>();
            for (int i = 0; i < 12; i++)
            {
                vListInt.Add(ro.Next(400, 500));
            }
            return Json(vListInt, JsonRequestBehavior.AllowGet);
        }
