水晶报表使用IEnumerable数据源

这篇我们学习水晶报表，报表呈现的数据源是IEnumerable<T>。比如下面的数据：

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using Insus.NET.Models;

namespace Insus.NET.Entities
{
    public class MachineEntity
    {
        public IEnumerable<Machine> Machines()
        {
            return new List<Machine>()
            {
                { new Machine() {
                    Key =1,
                    ModelNumber ="TC03Q",
                    Brand ="QT",
                    ManufactureDate = Convert.ToDateTime("2008/12/31")}
                },
                { new Machine() {
                    Key =2,
                    ModelNumber ="MH26U",
                    Brand ="HW",
                    ManufactureDate = Convert.ToDateTime("2012/03/09")}
                },
                { new Machine() {
                    Key =3,
                    ModelNumber ="DW569",
                    Brand ="XM",
                    ManufactureDate = Convert.ToDateTime("2015/07/25")}
                }
            };
        }
    }
}
