一、登錄數據庫，在數據庫中創建表User00，并且插入數據。

表的字段分別為：

Id(編號)、Name(姓名)、Grid(級別)、Score(積分)、Password(密碼)、Age(年齡)、Code(邀請碼)。（其中編號是自動編號）

部分命令如下：

select * from User00; /*查詢User00*/insert into User00 values('one','優',10000,'123',24); /*插入一行數據*/update User00 set Grid='優' where Id=001; /*更新已存在數據*/delete from User00; /*刪除表里所有數據*/alter table User00 rename Code to Code; /*更改字段名*/update User00 set Code =null; /*刪除某一列所有數據*/alter table User00 add Age number; /* user00中插入一列*/alter table User00 modify Age varchar2(4); /*更改某字段類型*/delete from User00 where Score is null; /*刪除密碼為空的所有行*/

二、新建mvc項目kaohe00，添加一個控制器Home。

using System;using System.Collections.Generic;using System.Linq;using System.Web;using System.Web.Mvc;using Model;using log4net;using System.Reflection;//using Bll;namespace kaohe00.Models{public class HomeController : Controller{////數據庫 數據庫的private static Bll.Test00 test00 = new Bll.Test00("Data Source=YWW;User Id=Test00;Password=Test00;"); //連接數據庫// GET: /Home/public ActionResult Index() //顯示主頁的動作方法{return View();}public JsonResult ShowInfo() //把數據庫里的表的數據發送到前臺的方法{var list = test00.GetList(); //return Json(new { Rows = list, Total = list.Count }, JsonRequestBehavior.AllowGet);}public ActionResult Register() //注冊的動作方法{return View();}}}

三、為Home的Index添加一個視圖，顯示主頁的信息，將數據庫的表User00的數據放到主頁視圖的表格中。

1、主頁視圖代碼：

@{ViewBag.Title = "Index";}<script src="~/Content/jquery/jquery-1.9.0.min.js"></script><script src="~/Content/script/common.js"></script><script src="~/Content/ligerui/ligerui.all.js"></script><link href="~/Content/ligerui/skins/Aqua/css/ligerui-all.css" rel="stylesheet" /><head><title>我的主頁</title></head><div id="maingrid"></div><script type="text/javascript">$(function () {$("#maingrid").ligerGrid({columns: [{ display: '編號', name: 'Id',heigth:100,width:250 },{ display: '姓名', name: 'Name', heigth: 100, width: 250 },{ display: '積分', name: 'Score', heigth: 100, width: 250 },{ display: '密碼', name: 'Password', heigth: 100, width: 250 },{ display: '級別', name: 'Grid', heigth: 100, width: 250 },{ display: '邀請碼', name: 'Code', heigth: 100, width: 250 }],url: "/Home/ShowInfo", //調用顯示自己信息的動作方法});});</script>

2、主頁視圖界面：

四、實現登錄功能

1、添加一個Login控制器。

using System;using System.Collections.Generic;using System.Linq;using System.Web;using System.Web.Mvc;namespace kaohe00.Controllers{public class LoginController : Controller{//// GET: /Login///數據庫private static Bll.Test00 test00 = new Bll.Test00("Data Source=YWW;User Id=Test00;Password=Test00;"); //連接數據庫public ActionResult Index(){return View();}public JsonResult LoginTest(string Id ,string Password) //登錄驗證動作方法{var succ = test00.LoginTest(Id, Password);return Json(new { Succ = succ });}}}

2.1、為Login的Index添加一個視圖

視圖代碼:

@{ViewBag.Title = "Index";}<script src="~/Content/jquery/jquery-1.9.0.min.js"></script><script src="~/Content/script/common.js"></script><script src="~/Content/ligerui/ligerui.all.js"></script><link href="~/Content/ligerui/skins/Aqua/css/ligerui-all.css" rel="stylesheet" /><head><title>登錄</title></head><div id="login"><div id="Lform"></div></div><script type="text/javascript">$(function () {$("#Lform").ligerForm({fields: [{ display: "編號", name: "Id", newline: false, type: "text", },{ display: "密碼", name: "Password", newline: true, type: "password", }],});$.ligerDialog.open({target: $("#login"),title: "登錄",allowClose: false,buttons: [{text: '登錄', onclick: function (item, dialog) {var form = liger.get("Lform");var data = form.getData();if(data.Id==""||data.Password==""){alert("用戶名或密碼不能為空");return false;}$.post("/Login/LoginTest", data, function (result) {//alert(result.Succ);if(result.Succ == true) {window.document.location.href = "/Home/Index";}else {alert("登錄失敗");return false;}});}},{text: '注冊', onclick: function (item, dialog) {window.document.location.href = "/Register/Index";}},]});});</script>

2.2、登錄視圖的界面：

五、實現注冊功能

1、添加一個注冊控制器Register

using System;using System.Collections.Generic;using System.Linq;using System.Web;using System.Web.Mvc;using Model;using log4net;using System.Reflection;namespace kaohe00.Controllers{public class RegisterController : Controller{//數據庫private static Bll.Test00 test00 = new Bll.Test00("Data Source=YWW;User Id=Test00;Password=Test00;");//// GET: /Register/public ActionResult Index(){return View();}public JsonResult Register(User00 user00){ var succ=test00.AddNew(user00)>0?1:0;return Json(new { Succ = succ }, JsonRequestBehavior.AllowGet);}}}

2.1、為注冊控制器Register的index添加一個視圖

@{ViewBag.Title = "Index";}<script src="~/Content/jquery/jquery-1.9.0.min.js"></script><script src="~/Content/script/common.js"></script><script src="~/Content/ligerui/ligerui.all.js"></script><link href="~/Content/ligerui/skins/Aqua/css/ligerui-all.css" rel="stylesheet" /><script src="scripts/jquery.validate.js" type="text/javascript"></script><head><title>注冊頁面</title></head><div id="reform"></div><div id="rebutton"><input style="margin-left:100px" type="button" value="注冊" onclick="register()"></div><script type="text/javascript">function register() {// alert("test");var form = liger.get("reform");// alert(form.name.getData);var data = form.getData();if (data.Name == "" || data.Password == ""||data.Grid == ""){alert("請完整填寫必填信息");return false;}//alert("test");$.post("/Register/Register", data,function (data) {alert("注冊成功");window.document.location.href = "/Home/Index";});}$(function () {$("#reform").ligerForm({inputWidth: 170, labelWidth: 90, space: 40,fields: [{ display: "姓名 ", name: "Name", newline: true, type: "text",validate:{required:true}},{ display: "密碼", name: "Password", newline: true, type: "password", type: "text", validate: { required: true } },{ display: "年齡", name: "Age", newline: true, type: "text" },{ display: "會員級別", name: "Grid", newline: true, type: "text", type: "text", validate: { required: true } },{ display: "邀請碼", name: "Code", newline: true, type: "text" }],});});</script>

2.2注冊視圖的界面

六、為數據庫的表建立Model模型實體類，建立一個類文件命名為User00.

using System;using System.Collections.Generic;using System.Linq;using System.Text;namespace Model{/// <summary>/// </summary>public class User00{public int Id { get; set; }public string Name { get; set; }public string Grid { get; set; }public int Score { get; set; }public string Password { get; set; }public int Age { get; set; }public int Code { get; set; }}}

七、前文出現的Bll命名空間和類Test00等一些代碼是引用了另外的庫。

1、目錄

2、其中文件Test00的代碼：

using Blocks.Data;using Blocks.Data.CustomType;using Blocks.Data.DbProviders.Oracle;using kaohe00.Mappings;using Model;using System;using System.Collections.Generic;using System.Linq;using System.Text;namespace Bll{public class Test00{/// <summary>/// 數據庫/// </summary>private Database oracle = null;public Test00(string connectionString) {this.oracle = new Database(new OracleDbProvider(connectionString));this.oracle.Mappings(typeof(User00Mapping).Assembly);}public List<User00> GetList() //定義GetList函數，其功能：獲得一個類型是User00類的列表相當于數組{var list = this.oracle.Select<User00>().ToList();return list;}public int AddNew(User00 user00){return this.oracle.Insert(user00);}public bool LoginTest(string Id,string Password) //函數功能：判斷前臺穿的值是否在數據庫中的{// var search = this.oracle.Select<User00>();// var list = search.Where(t => t.Id == int.Parse(Id)) && t.Password == Password; var search = this.oracle.Select<User00>().Where(t => t.Id == int.Parse(Id) && t.Password == Password);var list = search.ToList(); //list相當于數組if (list.Count > 0) //??!!{//var user = list.First();return true;}else{return false;}}}}

3、其中的kaohe00.Mappings文件里的User00Mapping.cs的文件的代碼：

using Blocks.Data.Mapping;using Model;using System;using System.Collections.Generic;using System.Linq;using System.Text;namespace kaohe00.Mappings{public class User00Mapping : ClassMap<User00>{public User00Mapping() {Map(t => t.Id).AutoNumber();Map(t => t.Name);}}}

八、設置路徑： defaults: new { controller = "Login", action = "Index", id = UrlParameter.Optional }，使其先執行Login。

九、查看效果：

1、點擊登錄后密碼錯誤的情況：
