mvc5+ef+ adminlte教程16-2：两张表进行汇总、对比分析（以欠费清单管理为例
接着上一章。
因为一效直在弄left join的加group by，没整好，所以先把index效果图弄出来。
其中红色为表1中的sum数据，蓝天 要取表2中的数据。
同时点最前面的部门和后面的“详单”都能弹到以部门名或责任人为搜索的清单页面。ArrearsList页面。
1.视图文件
注意视图中还有分页功能。
@model IEnumerable<jsdhh2.Models.NewArreartwo>
<div class="dhhheight1 col-md-12 col-xs-12"></div>
<!--start 右 -->
<div class="col-md-12 col-xs-12 pull-right">

}
2.后台的代码。
一是读取的显示代码v
// GET: 欠费用户清单
public ActionResult ArreasList(string seachDepart,string seachstring,int? page)
{
///只要几个数，主要是分类汇总。
ViewBag.seachstring = seachstring;
ViewBag.seachDepart = seachDepart;
if (!string.IsNullOrEmpty(seachstring)&& !string.IsNullOrEmpty(seachDepart))
{
page = 1;
}
int pageNumber = page ?? 1;
int pageSize = 4;
if (!string.IsNullOrEmpty(seachstring))
{
var seachindexlist1 = (from w in db.NewArrearones
join yy in db.NewArreartwos
on w.Number equals yy.Number
select w).Where(x => x.ResponsiblePeople == seachstring).OrderByDescending(x => x.TotalMoney);
return View(seachindexlist1.ToPagedList(pageNumber, pageSize));
}
var seachindexlist = (from w in db.NewArrearones
join yy in db.NewArreartwos
on w.Number equals yy.Number
select w).Where(x => x.ResponsibleDePart == seachDepart).OrderByDescending(x => x.TotalMoney);
return View(seachindexlist.ToPagedList(pageNumber, pageSize));
}
二是导出EXCLE代码
//导出的方法Npoi:有搜索字符串的
public FileResult ToExlceseachArrears(string seachstring, string seachDepart)
{
//创建Excel文件的对象
HSSFWorkbook book = new HSSFWorkbook();
//添加一个sheet
ISheet sheet1 = book.CreateSheet("Sheet1");
//获取list数据，因是最新欠费表，可能需要关联责任人与责任部门，主要原因是只有月初才分配清单。以后只是对比,所以字段全是表1。
List<NewArrearone> listRainInfo = new List<NewArrearone>();
if (!string.IsNullOrEmpty(seachstring))
{
//同时要还取一个WHERE,当责任人的搜索关键字不为空的时候，为空则是部门
var bijiao = ((from m in db.NewArrearones
join mr in db.NewArreartwos
on m.Number equals mr.Number
select m).Where(x => x.ResponsiblePeople == seachstring)).ToList();
listRainInfo = bijiao;
}
else
{
var bijiao1 = ((from m in db.NewArrearones
join mr in db.NewArreartwos
on m.Number equals mr.Number
select m).Where(x => x.ResponsibleDePart == seachDepart)).ToList();
listRainInfo = bijiao1;
}
//给sheet1添加第一行的头部标题
NPOI.SS.UserModel.IRow row1 = sheet1.CreateRow(0);
//从第2列开始写，第一列是guid.ID
row1.CreateCell(1).SetCellValue("序号");
row1.CreateCell(2).SetCellValue("用户名");
row1.CreateCell(3).SetCellValue("号码");
row1.CreateCell(4).SetCellValue("账号ID");
row1.CreateCell(5).SetCellValue("联系电话");
row1.CreateCell(6).SetCellValue("产品");
row1.CreateCell(7).SetCellValue("套餐");
row1.CreateCell(8).SetCellValue("当月金额");
row1.CreateCell(9).SetCellValue("总金额");
row1.CreateCell(10).SetCellValue("账龄");
row1.CreateCell(11).SetCellValue("地址");
row1.CreateCell(12).SetCellValue("付费类型");
row1.CreateCell(13).SetCellValue("责任部门");
row1.CreateCell(14).SetCellValue("责任人");
row1.CreateCell(15).SetCellValue("备注哟");
//将数据逐步写入sheet1各个行
for (int i = 0; i < listRainInfo.Count; i++)
{
NPOI.SS.UserModel.IRow rowtemp = sheet1.CreateRow(i + 1);
//也从第二列开始写
rowtemp.CreateCell(1).SetCellValue(listRainInfo[i].SerialNumber.ToString());
rowtemp.CreateCell(2).SetCellValue(listRainInfo[i].UserName.ToString());
rowtemp.CreateCell(3).SetCellValue(listRainInfo[i].Number.ToString());
rowtemp.CreateCell(4).SetCellValue(listRainInfo[i].AccountId.ToString());
rowtemp.CreateCell(5).SetCellValue(listRainInfo[i].ContactNumber.ToString());
rowtemp.CreateCell(6).SetCellValue(listRainInfo[i].Product.ToString());
rowtemp.CreateCell(7).SetCellValue(listRainInfo[i].Package.ToString());
rowtemp.CreateCell(8).SetCellValue(listRainInfo[i].AmountMoney);
rowtemp.CreateCell(9).SetCellValue(listRainInfo[i].TotalMoney);
rowtemp.CreateCell(10).SetCellValue(listRainInfo[i].Aging);
rowtemp.CreateCell(11).SetCellValue(listRainInfo[i].Address.ToString());
rowtemp.CreateCell(12).SetCellValue(listRainInfo[i].PayType.ToString());
rowtemp.CreateCell(13).SetCellValue(listRainInfo[i].ResponsibleDePart.ToString());
rowtemp.CreateCell(14).SetCellValue(listRainInfo[i].ResponsiblePeople.ToString());
rowtemp.CreateCell(15).SetCellValue(listRainInfo[i].Bei.ToString());
}
// 写入到客户端
System.IO.MemoryStream ms = new System.IO.MemoryStream();
book.Write(ms);
ms.Seek(0, SeekOrigin.Begin);
return File(ms, "application/vnd.ms-excel", seachstring+ seachDepart+"最新欠费表.xls");
}
测试导出功能正常，还有删除，我默认的没有管他
8,现在来实现index汇总页面的功能。
注意代码中的.tolist()必须要呀，要不然要出错，在select new前必须是tolist()
代码。有点复杂，就不一一说明了，有了注解，我笨，所以用四步来实现。
// GET: NewArrearones
public ActionResult Index()
{
///下面这个先用左join接两个表，因为表2可能是空表，所以对空间中几个int,double字段进行赋值。同时对关键的二个主体字段赋值，用于再次group by
var y = from m in db.NewArrearones.ToList()
join mr in db.NewArreartwos.ToList() on m.Number equals mr.Number into newTable
from item in newTable.DefaultIfEmpty(new NewArreartwo { AmountMoney = 0, TotalMoney = 0, Aging = 0, ResponsiblePeople = m.ResponsiblePeople, ResponsibleDePart = m.ResponsibleDePart })
select item;
//以Y表进行group by
var yy =from mm in y group mm by mm.ResponsiblePeople into mg
select new ArrearsView
{
ResponsibleDePart = mg.FirstOrDefault().ResponsibleDePart,
ResponsiblePeople = mg.Key,
StartAmount = 0,
NewAmount = mg.Sum(m => m.Aging),
StartMoney = 0,
NewMoney = mg.Sum(m => m.AmountMoney)
};
////对表1进行GROU 到NEW 的ArrearsVIew型型。
var xx = from x in db.NewArrearones.ToList()
group x by x.ResponsiblePeople into g
select new ArrearsView
{
ResponsibleDePart = g.FirstOrDefault().ResponsibleDePart,
ResponsiblePeople = g.Key,
StartAmount = g.Sum(m => m.Aging),
NewAmount = 0,
StartMoney = g.Sum(m => m.AmountMoney),
NewMoney = 0
};
//两张表连接
var arrrarviewlist = (from xxyy in yy
join xxxy in xx on xxyy.ResponsiblePeople equals xxxy.ResponsiblePeople
select new ArrearsView
{
ResponsibleDePart = xxxy.ResponsibleDePart,
ResponsiblePeople = xxxy.ResponsiblePeople,
StartAmount = xxxy.StartAmount,
NewAmount =xxyy.NewAmount,
StartMoney = xxxy.StartMoney,
NewMoney = xxyy.NewMoney
}).OrderBy(my => my.ResponsibleDePart); ;
return View(arrrarviewlist);
//return View(await db.NewArrearones.ToListAsync());
}
