关于MVC工厂模式的增删改查sql存储过程
这里MVC中用到了反射,工厂,泛型,接口
在搭建框架的时候,除了MVC的三层以外,还有泛型的接口层和工厂层
下面是dal层调用sql存储过程,增删改查,dal层继承了接口层,实现了接口层里面的方法
1 namespace DAL
2 {
3 public class DalHouse : IHouse
4 {
5 public int Add(HouseInfo m)
6 {
7 string sql = "pro_add";
8 SqlParameter eid = new SqlParameter("@eid", m.Eid);
9 SqlParameter bid = new SqlParameter("@bid", m.Bid);
10 SqlParameter floornum = new SqlParameter("@floornum", m.FloorNum);

17 SqlParameter[] paras = new SqlParameter[] { eid, bid, floornum, roomnum, spaces, ads, tid, sids, uid };
18 int i = DbHelperSQL.ExecuteNonQuery(DbHelperSQL.ConnB2c, CommandType.StoredProcedure, sql, paras);
19 return i;
20 }

36 DataTable dt= DbHelperSQL.ExecuteDataTable(DbHelperSQL.ConnB2c,CommandType.StoredProcedure,sql,paras);
37 List<HouseInfo> info = JsonConvert.DeserializeObject<List<HouseInfo>>(JsonConvert.SerializeObject(dt));
38 return info[0];
39 }

54 page.Direction = ParameterDirection.Output;
55 SqlParameter[] paras = new SqlParameter[] { paraEid, paraBid, paraTid, paraSid, paraAddress, paraSize, count, paraIndex, page };
56 DataTable dt= DbHelperSQL.ExecuteDataTable(DbHelperSQL.ConnB2c,CommandType.StoredProcedure,sql,paras);
57 PageList p = new PageList();
58 p.TotalCount = Convert.ToInt32(count.Value);
59 p.TotalPage = Convert.ToInt32(page.Value);
60 p.House = JsonConvert.DeserializeObject<List<HouseInfo>>(JsonConvert.SerializeObject(dt));
61 return p;
62 }
63
64 public List<Building> ShowBuilding()
65 {
66 string sql = "select * from Building";
67 DataTable dt= DbHelperSQL.ExecuteDataTable(DbHelperSQL.ConnB2c,CommandType.Text,sql);
68 return JsonConvert.DeserializeObject<List<Building>>(JsonConvert.SerializeObject(dt));

73 {
74 string sql = "select * from BuildStruct";
75 DataTable dt = DbHelperSQL.ExecuteDataTable(DbHelperSQL.ConnB2c, CommandType.Text, sql);
76 return JsonConvert.DeserializeObject<List<BuildStruct>>(JsonConvert.SerializeObject(dt));
77 }
78
79 public List<HouseEatate> ShowEstate()
80 {
81 string sql = "select * from HouseEstate";
82 DataTable dt = DbHelperSQL.ExecuteDataTable(DbHelperSQL.ConnB2c, CommandType.Text, sql);
83 return JsonConvert.DeserializeObject<List<HouseEatate>>(JsonConvert.SerializeObject(dt));
84 }
85
86 public List<States> ShowStates()
87 {
88 string sql = "select * from States";
89 DataTable dt = DbHelperSQL.ExecuteDataTable(DbHelperSQL.ConnB2c, CommandType.Text, sql);
90 return JsonConvert.DeserializeObject<List<States>>(JsonConvert.SerializeObject(dt));
91 }
92
93 public List<HouseType> ShowType()
94 {
95 string sql = "select * from HouseType";
96 DataTable dt = DbHelperSQL.ExecuteDataTable(DbHelperSQL.ConnB2c, CommandType.Text, sql);
97 return JsonConvert.DeserializeObject<List<HouseType>>(JsonConvert.SerializeObject(dt));
98 }
99
100 public int Update(HouseInfo m)
101 {
102 string sql = "pro_update";
103 SqlParameter id = new SqlParameter("@id", m.Id);
104 SqlParameter eid = new SqlParameter("@eid",m.Eid);

114 int i= DbHelperSQL.ExecuteNonQuery(DbHelperSQL.ConnB2c,CommandType.StoredProcedure,sql,paras);
115 return i;
116
117 }
118 }
119 }
这是controller与前台交互,控制器里面的方法需要注意的是下拉的绑定,还有分部视图的使用
我用的是强类型视图,所以视图页面和控制器里面参数的变量名要一致,否则控制器中的方法接受不到值的

d.Size = size;
BllHouse bll = new BllHouse();
PageList info = bll.ShowAll(d);
ViewBag.totalpage = info.TotalPage;
ViewBag.totalcount = info.TotalCount;

}
public int DeleteAll(string id)
{
BllHouse bll = new BllHouse();
int i = bll.Delete(id);
return i;
}
public void Delete(string id)
{
BllHouse bll = new BllHouse();
int i = bll.Delete(id);
if (i > 0)
{
Response.Write("<script>alert('删除成功');location.href='/house/index/1'</script>");
}
else
{

}

[HttpPost]
public void Update(HouseInfo h)
{

int i = bll.Update(h);
if (i > 0)
{
Response.Write("<script>alert('修改成功');location.href='/house/index/1'</script>");
}

{
Response.Write("<script>alert('修改失败')</script>");
}
}
public ActionResult Add()
{

return View();
}
[HttpPost]
public ActionResult Add(HouseInfo h)
{
BllHouse bll = new BllHouse();
int i = bll.Add(h);
if (i > 0)
{
return Content("<script>alert('添加成功');location.href='/house/index/1'</script>");
}
else
{
return Content("<script>alert('添加失败')</script>");
} }
}
}
这里需要说一下,jquery写的全选和批删的方法,详情看代码
<script>
//全选
$(function () {
$("#CheckAll").click(function () {
if (this.checked) {
$("input[name='check']").each(function () {
this.checked = true;
})
} else {
$("input[name='check']:checked").each(function () {
this.checked = false;
})
} })
})
function DelAll() {
var check = [];
$("input[name='check']:checked").each(function () {
check.push($(this).val());
})
if (check == 0) {
alert("请先进行选择");
}
else {
$.ajax({
type: "post",
url: "/house/deleteall",
data: { id: check.toString() },
success: function (a) {
if (a > 0) {
alert("批量删除成功!");
location.reload();
}
}
})
} }
</script>
基本的页面布局,这里就不展示了,
还需要说的就是使用强类型视图,在修改的时候,
需要使用@html.Hidden("Id")
