MVC 入門自動生成增刪改查所有功能

本文轉載自查看原文 2014-03-26 10:03 6020 EF/ MVC

MVC現在版本已經是5了 EF現在最新的應該是6.0.2了

開發工具是 Visual Studio2013

數據庫是 SQL Server 2012

這些需要.NET Framework4.5 的支持

如果沒安裝的同學可以先安裝一下.NET Framework4.5

首先打開我們的開發環境，

把項目創建好了以后，

當然我這里是我之前寫好的，我就不創建了

項目目錄結構

現在在Models文件夾下邊創建一個

創建一個數據庫 MVCtest_DB

USE [MVCtest_DB]
GO

/****** Object:  Table [dbo].[UserTab]    Script Date: 2014/3/26 9:23:26 ******/
SET ANSI_NULLS ON
GO

SET QUOTED_IDENTIFIER ON
GO

SET ANSI_PADDING ON
GO

CREATE TABLE [dbo].[UserTab](
    [UID] [int] IDENTITY(1,1) NOT NULL,
    [UserName] [varchar](50) NULL,
    [UserPassword] [varchar](50) NULL,
    [status] [int] NULL,
 CONSTRAINT [PK_UserTab] PRIMARY KEY CLUSTERED 
(
    [UID] ASC
)WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON) ON [PRIMARY]
) ON [PRIMARY]

GO

SET ANSI_PADDING OFF
GO

USE [MVCtest_DB]
GO

/****** Object:  Table [dbo].[RoleTab]    Script Date: 2014/3/26 9:24:38 ******/
SET ANSI_NULLS ON
GO

SET QUOTED_IDENTIFIER ON
GO

SET ANSI_PADDING ON
GO

CREATE TABLE [dbo].[RoleTab](
    [RID] [int] IDENTITY(1,1) NOT NULL,
    [Role] [varchar](500) NULL,
 CONSTRAINT [PK_RoleTab] PRIMARY KEY CLUSTERED 
(
    [RID] ASC
)WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON) ON [PRIMARY]
) ON [PRIMARY]

GO

SET ANSI_PADDING OFF
GO

創建兩張表

到這里准備工作基本完成。

連接數據庫

點擊下一步

連接好了之后

完成！

在Controllers里邊添加一個控制器 UserController

選擇控制器

好了等着 vs自己創建框架視圖等

 public class UserController : Controller
    {
        private MVCtest_DBEntities db = new MVCtest_DBEntities();

        // GET: /User/
        public async Task<ActionResult> Index()
        {
            return View(await db.UserTabs.ToListAsync());
        }

        // GET: /User/Details/5
        public async Task<ActionResult> Details(int? id)
        {
            if (id == null)
            {
                return new HttpStatusCodeResult(HttpStatusCode.BadRequest);
            }
            UserTab usertab = await db.UserTabs.FindAsync(id);
            if (usertab == null)
            {
                return HttpNotFound();
            }
            return View(usertab);
        }

        // GET: /User/Create
        public ActionResult Create()
        {
            return View();
        }

        // POST: /User/Create
        // 為了防止“過多發布”攻擊，請啟用要綁定到的特定屬性，有關 
        // 詳細信息，請參閱 http://go.microsoft.com/fwlink/?LinkId=317598。
        [HttpPost]
        [ValidateAntiForgeryToken]
        public async Task<ActionResult> Create([Bind(Include="UID,UserName,UserPassword,status")] UserTab usertab)
        {
            if (ModelState.IsValid)
            {
                db.UserTabs.Add(usertab);
                await db.SaveChangesAsync();
                return RedirectToAction("Index");
            }

            return View(usertab);
        }

        // GET: /User/Edit/5
        public async Task<ActionResult> Edit(int? id)
        {
            if (id == null)
            {
                return new HttpStatusCodeResult(HttpStatusCode.BadRequest);
            }
            UserTab usertab = await db.UserTabs.FindAsync(id);
            if (usertab == null)
            {
                return HttpNotFound();
            }
            return View(usertab);
        }

        // POST: /User/Edit/5

        // 詳細信息，請參閱 http://go.microsoft.com/fwlink/?LinkId=317598。
        [HttpPost]
        [ValidateAntiForgeryToken]
        public async Task<ActionResult> Edit([Bind(Include="UID,UserName,UserPassword,status")] UserTab usertab)
        {
            if (ModelState.IsValid)
            {
                db.Entry(usertab).State = EntityState.Modified;
                await db.SaveChangesAsync();
                return RedirectToAction("Index");
            }
            return View(usertab);
        }

        // GET: /User/Delete/5
        public async Task<ActionResult> Delete(int? id)
        {
            if (id == null)
            {
                return new HttpStatusCodeResult(HttpStatusCode.BadRequest);
            }
            UserTab usertab = await db.UserTabs.FindAsync(id);
            if (usertab == null)
            {
                return HttpNotFound();
            }
            return View(usertab);
        }

        // POST: /User/Delete/5
        [HttpPost, ActionName("Delete")]
        [ValidateAntiForgeryToken]
        public async Task<ActionResult> DeleteConfirmed(int id)
        {
            UserTab usertab = await db.UserTabs.FindAsync(id);
            db.UserTabs.Remove(usertab);
            await db.SaveChangesAsync();
            return RedirectToAction("Index");
        }

        protected override void Dispose(bool disposing)
        {
            if (disposing)
            {
                db.Dispose();
            }
            base.Dispose(disposing);
        }
    }
