Question

所以，我正在尝试了解如何将数据导入Kendo UI小部件。小部件是treeview。当然我想用remote data来做。

因此，该网站的演示文档将我带到了这段代码中以获取数据。但我不知道发生了什么。我知道这是一个访问数据的sql语句。但是，我不确定一些语法。比如，?, hasChildren = e.Employees1.Any(), :，方法的签名和return语句（我得到employees变量，但不是jsonRequestBehavior）。

public JsonResult Employees(int? id)
        {
            var dataContext = new Client();

            var employees = from e in dataContext.ClientName
                            where (id.HasValue ? e.ReportsTo == id : e.ReportsTo == null)
                            select new
                            {
                                id = e.EmployeeID,
                                Name = e.FirstName + " " + e.LastName,
                                hasChildren = e.Employees1.Any()
                            };

            return Json(employees, JsonRequestBehavior.AllowGet);
        }

最初的陈述是......

using System.Web.Mvc;
using System.Linq;
using Kendo.Mvc.Examples.Models;

namespace Kendo.Mvc.Examples.Controllers
{
    public partial class TreeViewController : Controller
    {
        [Demo]
        public ActionResult Remote_Data_Binding()
        {
            return View();
        }

        public JsonResult Employees(int? id)
        {
            var dataContext = new SampleEntities();

            var employees = from e in dataContext.Employees
                            where (id.HasValue ? e.ReportsTo == id : e.ReportsTo == null)
                            select new {
                                id = e.EmployeeID,
                                Name = e.FirstName + " " + e.LastName,
                                hasChildren = e.Employees1.Any()
                            };

            return Json(employees, JsonRequestBehavior.AllowGet);
        }
    }
}

理解json语句
