记录下工作中用MVC写的一个机器信息管理平台。
1. 业务需求
- 搭建一个组内平台，管理组员名下所有的VM，内容包括，VM名称、基本系统信息、所安装的主要测试工具版本、VM主人、VM主要用途
- 要求页面可编辑，可增删改查VM信息
2. 使用技术
- Visual Studio 2013/MVC/C#
- SQL Server
进入正题，大家都知道MVC框架技术分为Model, View, Controller三层，在View视图呈现层的基本代码呈现如下：
1 @model PagedList.IPagedList<Advent.GenevaQA.Dashboard.Data.GenevaMachineStatu>
2 @using PagedList.Mvc;
3
4
5 @using (Html.BeginForm("Index", "Machine", FormMethod.Post))
6 {
7 @Html.AntiForgeryToken()
8
9 <div class="panel panel-primary">
10 <div class="panel-heading">
11 <h3 class="panel-title" style="color:white"><strong>Geneva QA Machine List</strong></h3>
12 </div>
13 <div class="panel-body">
14
15 <table>
16 @using (Html.BeginForm())
17 {
18 @Html.AntiForgeryToken()
19 @Html.ValidationSummary(true)
20
21 <tr>
22 <td>@Html.Label("Machine Name : ", new { style = "font-weight:strong" })</td>
23 <td>@Html.TextBox("search", null, new { @class = "", placeholder = "Partial or full machine name" })</td>
24 <td>
25 <button type="submit" value="Index" name="action" class="btn btn-default">Find</button>
26 </td>
27 <td>
28 <button type="button" onclick="location.href=‘@Url.Action("Create", "Machine")‘;" class="btn btn-default">AddNewMachine</button>
29 </td>
30 </tr>
31 }
32 </table>
33
34 @if (Model != null && Model.Count() > 0)
35 {
36 <div id="sourcelist">
37 <table class="table table-striped table-hover">
38 <tr>
39 <th>
40 Name
41 </th>
42 <th>
43 Owner
44 </th>
45 <th>
46 OS/bit
47 </th>
48 <th>
49 SQL
50 </th>
51 <th>
52 IE
53 </th>
54 <th>
55 Purpose
56 </th>
57 <th>
58 Management
59 </th>
60 </tr>
61 @foreach (var item in Model)
62 {
63 <tr>
64 <td>
65 @Html.ActionLink(item.Machine_Name, "Details", new { machineName = item.Machine_Name })
66 </td>
67 <td>
68 @Html.DisplayFor(modelItem => item.Owner)
69 </td>
70 <td>
71 @Html.DisplayFor(modelItem => item.OS_Version_Bit)
72 </td>
73 <td>
74 @Html.DisplayFor(modelItem => item.SQL_Server)
75 </td>
76 <td>
77 @Html.DisplayFor(modelItem => item.IE)
78 </td>
79 <td>
80 @Html.DisplayFor(modelItem => item.Purpose)
81 </td>
82 <td>
83 @Html.ActionLink("Update", "Edit", new { machineName = item.Machine_Name }) |
84 @Html.ActionLink("Delete", "Delete", new { machineName = item.Machine_Name })
85 </td>
86 </tr>
87 }
88 </table>
89 @Html.PagedListPager(Model, page => Url.Action("Index", "Machine", new { page }))
90 </div>
91 }
92 else
93 {
94 <table class="table table-striped table-hover">
95 <tr>
96 <td>
97 <div class="alert alert-warning">No Records</div>
98 </td>
99 </tr>
100 </table>
101 }
102
103 </div>
104
105 </div>
106 }
- 第一行代码中 model的实例化很重要
- using块的巧妙使用
Model层：
1 using System;
2 using System.Collections.Generic;
3 using System.Linq;
4 using System.Web;
5
6 namespace Advent.GenevaQA.Dashboard.Models
7 {
8 public class CreateMachineMode
9 {
10
11 public string Machine_Name { get; set; }
12 public string Owner { get; set; }
13 public string Status { get; set; }
14 public string Domain { get; set; }
15 public string Purpose { get; set; }
16 public string OS_Version_Bit { get; set; }
17 public int? Memory_GB_ { get; set; }
18 public int? Hard_Disk_GB_ { get; set; }
19 public string Special_Software { get; set; }
20 public string VS_Version { get; set; }
21 public string SQL_Server { get; set; }
22 public string IE { get; set; }
23 public string Comments { get; set; }
24 public string Updated_by { get; set; }
25 public DateTime? CreatTime { get; set; }
26 public DateTime? UpdateTime { get; set; }
27
28 }
29 }
Controller层：
1 using System;
2 using System.Collections.Generic;
3 using System.Linq;
4 using System.Web;
5 using System.Web.Mvc;
6 using Advent.GenevaQA.Dashboard.Data;
7 using Advent.GenevaQA.Dashboard.Data.DBHelper;
8 using PagedList;
9 using Advent.GenevaQA.Dashboard.Models;
10 using System;
11 using System.Configuration;
12 using System.Runtime.InteropServices;
13
14 namespace Advent.GenevaQA.Dashboard.Controllers
15 {
16 public class MachineController : Controller
17 {
18 int pageSize = 15;
19 //
20 // GET: /Machine/
21
22 public ActionResult Index(string search, int? page)
23 {
24 IEnumerable<GenevaMachineStatu> list = null;
25 string filter = string.Empty;
26
27 if (page == null)
28 {
29 Session["search"] = search;
30 filter = search;
31 }
32 else
33 {
34 filter = Convert.ToString(Session["search"]);
35 }
36
37 using(GenevaMachineManagement gmm = new GenevaMachineManagement())
38 {
39 //if page = 0 or null, pageNumber =1, else pageNumber = page
40 int pageNumber = (page ?? 1);
41
42 if (!string.IsNullOrEmpty(filter))
43 {
44 List<GenevaMachineStatu> mList = new List<GenevaMachineStatu>();
45 //list = gmm.GetAllMachines().Where(x => (x.Machine_Name+x.OS_Version_Bit+x.SQL_Server+x.Special_Software+x.Owner+x.IE).ToLower().Contains(search.ToLower())).ToPagedList(pageNumber, pageSize);
46 foreach (GenevaMachineStatu model in gmm.GetAllMachines())
47 {
48 if (string.Format(model.Machine_Name + model.Owner + model.OS_Version_Bit + model.SQL_Server + model.Special_Software + model.IE).ToLower().Contains(filter.ToLower()))
49 {
50 mList.Add(model);
51 }
52 }
53 list = mList.ToPagedList(pageNumber, pageSize);
54 }
55 else
56 {
57 list = gmm.GetAllMachines().ToPagedList(pageNumber, pageSize);
58 }
59 }
60
61 return View(list);
62 }
63 }
64 }
这里的pageNumber的定义需要注意下，涉及到翻页刷新的问题。
数据库
使用ADO.NET Entity Data Model链接数据库后增加相应的增删改查方法即可：
1 using System;
2 using System.Collections.Generic;
3 using System.Data.Entity.Infrastructure;
4 using System.Data.Entity.Validation;
5 using System.Linq;
6 using System.Text;
7
8 namespace Advent.GenevaQA.Dashboard.Data.DBHelper
9 {
10 public class GenevaMachineManagement:IDisposable
11 {
12 GenQADashboardEntities entity = new GenQADashboardEntities();
13
14 /// <summary>
15 ///
16 /// </summary>
17 /// <param name="machine"></param>
18 public void AddMachine(GenevaMachineStatu machine)
19 {
20 try
21 {
22 GenevaMachineStatu newmachine = new GenevaMachineStatu();
23 newmachine.Machine_Name = machine.Machine_Name;
24 newmachine.Owner = machine.Owner;
25 newmachine.Comments = machine.Comments;
26 newmachine.CreatTime = machine.CreatTime;
27 newmachine.Domain = machine.Domain;
28 newmachine.Hard_Disk_GB_ = machine.Hard_Disk_GB_;
29 newmachine.IE = machine.IE;
30 newmachine.Memory_GB_ = machine.Memory_GB_;
31 newmachine.OS_Version_Bit = machine.OS_Version_Bit;
32 newmachine.Purpose = machine.Purpose;
33 newmachine.Special_Software = machine.Special_Software;
34 newmachine.SQL_Server = machine.SQL_Server;
35 newmachine.Status = machine.Status;
36 newmachine.Updated_by = machine.Updated_by;
37 newmachine.UpdateTime = machine.UpdateTime;
38 newmachine.VS_Version = machine.VS_Version;
39
40 entity.GenevaMachineStatus.Add(newmachine);
41 entity.SaveChanges();
42 }
43 catch (DbEntityValidationException dbvex)
44 {
45
46 }
47 catch (DbUpdateException dbuex)
48 {
49
50 }
51 catch (InvalidOperationException ioex)
52 {
53
54 }
55 catch (NotSupportedException nsex)
56 {
57
58 }
59 }
60
61 /// <summary>
62 ///

65 public List<GenevaMachineStatu> GetAllMachines()

70 select m;

73 machines = query.ToList();
74
75 return machines;
76 }
77 }
