首次做MVC小项目，感觉挺好的，下面来展示下我的第一个MVC小项目：
1：文件布局
2.数据表
3.
CS_Guestbook类代码：
GuestbookController代码：
using System; using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.Mvc;
using Guestbook.Models;
using Guestbook.Controllers;
namespace Guestbook.Controllers {
public class GuestbookController : Controller
{ // // GET: /Guestbook/
public ActionResult Index()
{
DB_GuestbookEntities db = new DB_GuestbookEntities();
var data = db.TB_Guestbook;
return View(data); }
public ActionResult Create()
{
return View();
}
[HttpPost]
public ActionResult Save(CS_Guestbook csdb)
{
DB_GuestbookEntities db = new DB_GuestbookEntities();
db.AddToTB_Guestbook(new TB_Guestbook()
{ Name = csdb.Name,
Email = csdb.Email,
Message = csdb.Message,
DataTime = DateTime.Now
});
db.SaveChanges();
ViewData["Name"] = csdb.Name;
ViewData["Email"] = csdb.Email;
ViewData["Message"] = csdb.Message;
ViewData["DateTime"] = DateTime.Now;
return View();
}
public ActionResult Edit(CS_Guestbook csdb)
{
DB_GuestbookEntities db = new DB_GuestbookEntities();
var data = db.TB_Guestbook.First(x => x.Id==csdb.Id);
data.Name = csdb.Name;
data.Message = csdb.Message;
data.Email = csdb.Email;
db.SaveChanges();
return View();
}
public ActionResult Delete(int Id)
{
DB_GuestbookEntities db = new DB_GuestbookEntities();
var data = db.TB_Guestbook.First(x => x.Id == Id);
db.DeleteObject(data);
db.SaveChanges();
Response.Redirect("/Guestbook/Index");
return View();
}
}
}
4.IndexView代码：
<h2>留言显示</h2>
<table>
<tr>
<th></th>
<th> Id </th>
<th> Name </th>
<th> Email </th>
<th> Message </th>
<th> DataTime </th>
</tr>
<% foreach (var item in Model) { %>
<tr>
<td>
<%: Html.ActionLink("更新", "Edit", new { id = item.Id })%>
<%: Html.ActionLink("删除", "Delete", new { id=item.Id })%>
</td>
<td>
<%: item.Id %>
</td>
<td>
<%: item.Name %>
</td>
<td>
<%: item.Email %>
</td>
<td>
<%: item.Message %>
</td>
<td>
<%: String.Format("{0:g}", item.DataTime) %>
</td>
</tr>
<% } %>
</table>
<p> <%: Html.ActionLink("留下足迹", "Create") %> </p>
5.CreateView代码：
<%@ Page Title="" Language="C#" MasterPageFile="~/Views/Shared/Site.Master" Inherits="System.Web.Mvc.ViewPage<Guestbook.Controllers.CS_Guestbook>" %>
<asp:Content ID="Content1" ContentPlaceHolderID="TitleContent" runat="server"> Create </asp:Content>
<asp:Content ID="Content2" ContentPlaceHolderID="MainContent" runat="server"> <h2>请留言</h2> <% Html.EnableClientValidation(); %> <%=Html.ValidationSummary() %> <% using (Html.BeginForm("Save", RouteData.Values["controller"].ToString())) { %> <%:Html.LabelFor(x => x.Name)%> <%:Html.TextBoxFor(x => x.Name)%> <%:Html.ValidationMessageFor(x=>x.Name) %> <br/><br/> <%:Html.LabelFor(x => x.Email)%> <%:Html.TextBoxFor(x => x.Email)%> <%:Html.ValidationMessageFor(x=>x.Email) %> <br/><br/> <%:Html.LabelFor(x => x.Message)%> <%:Html.TextAreaFor(x => x.Message)%> <%:Html.ValidationMessageFor(x=>x.Message) %> <br/> <input type="submit" value="猛点我便可留言！！" /> <%} %>
</asp:Content>
6.EditView代码：
<%@ Page Title="" Language="C#" MasterPageFile="~/Views/Shared/Site.Master" Inherits="System.Web.Mvc.ViewPage<Guestbook.Controllers.CS_Guestbook>" %>
<asp:Content ID="Content1" ContentPlaceHolderID="TitleContent" runat="server"> Edit </asp:Content>
<asp:Content ID="Content2" ContentPlaceHolderID="MainContent" runat="server">
<h2>Edit</h2>
<% using (Html.BeginForm()) {%> <%: Html.ValidationSummary(true) %> <fieldset> <legend>Fields</legend> <div class="editor-label"> <%: Html.LabelFor(model => model.Id) %> </div> <div class="editor-field"> <%: Html.TextBoxFor(model => model.Id) %> <%: Html.ValidationMessageFor(model => model.Id) %> </div> <div class="editor-label"> <%: Html.LabelFor(model => model.Name) %> </div> <div class="editor-field"> <%: Html.TextBoxFor(model => model.Name) %> <%: Html.ValidationMessageFor(model => model.Name) %> </div> <div class="editor-label"> <%: Html.LabelFor(model => model.Email) %> </div> <div class="editor-field"> <%: Html.TextBoxFor(model => model.Email) %> <%: Html.ValidationMessageFor(model => model.Email) %> </div> <div class="editor-label"> <%: Html.LabelFor(model => model.Message) %> </div> <div class="editor-field"> <%: Html.TextBoxFor(model => model.Message) %> <%: Html.ValidationMessageFor(model => model.Message) %> </div> <p> <input type="submit" value="猛点我来更新" /> </p> </fieldset>
<% } %>
<div> <%: Html.ActionLink("返回首页", "Index") %> </div>
