RouteConfig.cs代码:
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.Mvc;
using System.Web.Routing;
namespace MvcApplication1
{
public class RouteConfig
{
//定义:路由是定义如何处理客户端请求。
//路由名称的设置: 在路由设置中，路由名称是可选输入参数，路由名称可生产URL路由，但是在路由解析中没有什么作用。不过当使用路由名称来生产URL路由的时候，路由模块将快速定位到指定名称的路由，否则将会进行查询，直到找到对应的路由。
//顺序:路由表中的路由输入顺序应该按使用频率从前向后输入。最常用的放在最前面，此法方法不仅提高生产URL路由的效率，而且也提高路由解析的效率。因为在路由解析的过程中，一旦找到匹配的路由，就停止解析。
//注意:在改变路由存放位置时，路由的次序改变是否实质性的影响匹配的结果。
public static void RegisterRoutes(RouteCollection routes)
{
routes.IgnoreRoute("{resource}.axd/{*pathInfo}");
routes.MapRoute(
name: "Default1",
url: "find/{low}-{upp}",
defaults: new { controller = "Home", action = "FindByPrice", low=0,upp=100 }
);
routes.MapRoute(
name: "Default2",
url: "k{year}/{month}/{day}",
defaults: new { controller = "Home", action = "Show", year = "2015", month = "1", day = "1" }
);
routes.MapRoute(
name: "Default3",
url: "{k}-{parent}",
defaults: new { controller = "Home", action = "Show", parent = "" }
);
routes.MapRoute(
name: "Default",
url: "{controller}/{action}/{id}",
defaults: new { controller = "Home", action = "Index", id = UrlParameter.Optional }
);
}
}
}
控制器代码:
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.Mvc;
using MvcApplication1.Models;
namespace MvcApplication1.Controllers
{
public class HomeController : Controller
{
//
// GET: /Home/
public ActionResult Index()
{
return View();
}
public ActionResult FindByPrice(decimal low, decimal upp)
{
List<Car> list = new CarDA().SelectByPrice(low, upp);
return PartialView(list);
}
public string ShowParent(string parent)
{
return "父级下显示的视图...";
}
public string Show(int year, int month, int day)
{
return year + "年" + month + "月" + day + "日";
}
}
}
模型:
首先要用linq连接数据库 然后建一个类开始写方法:
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
namespace MvcApplication1.Models
{
public class CarDA
{
private MyDBDataContext _context = new MyDBDataContext();
public List<Car> Select()
{
return _context.Car.ToList();
}
public List<Car> SelectByPrice(decimal low, decimal upp)
{
var query = _context.Car.Where(p => p.Price >= low && p.Price <= upp);
return query.ToList();
}
}
}
视图代码:
@{
Layout = null;
}
<!DOCTYPE html>
<html>
<head>
<meta name="viewport" content="width=device-width" />
<title>Index</title>
<script src="~/Script/jquery-1.7.1.min.js"></script>
<script>
function test() {
var low = $("#low").val();
var upp = $("#upp").val();
$("#dd").load("/find/" + low + "-" + upp);
}
</script>
</head>
<body>
<div>
<div>
@Html.ActionLink("此处走第二个路径 ", "Show", new { year=2015, month=7,day=11})<br>
@Html.ActionLink("此处走第三个路径 ", "ShowParent", new {parent=""})<br>
@using (Html.BeginForm("FindByPrice", "Home"))
{
<div>
最低价格：@Html.TextBox("low")
最高价格：@Html.TextBox("upp")
<input type="button" onclick="test()" value="查询" />
</div>
}
</div>
<div id="dd"></div>
</div>
</body>
</html>
部分视图代码:
@using MvcApplication1.Models
@model List<Car>
<ul>
@foreach(Car data in Model){
<li>@data.Name @(data.Price)</li>
}
</ul>
