Razor小案例
Model
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
namespace Razor.Models
{
public class Product
{
public int ProductID { get; set; }
public string Name { get; set; }
public string Description { get; set; }
public decimal Price { get; set; }
public string Category { set; get; }
}
}
Controller
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.Mvc;
using Razor.Models;
namespace Razor.Controllers
{
public class HomeController : Controller
{
Product myProduct = new Product
{
ProductID = 1,
Name = "Kayak",
Description = "A boat for one person",
Category = "Watersports",
Price = 275M
}; // 定义一个全局对象
public ActionResult Index()
{
return View(myProduct);
}
public ActionResult About()
{
ViewBag.Message = "Your application description page.";
return View();
}
public ActionResult Contact()
{
ViewBag.Message = "Your contact page.";
return View();
}
}
}
View
@model Razor.Models.Product
@{
Layout = null;
}
<!DOCTYPE html>
<html>
<head>
<meta name="viewport" content="width=device-width" />
<title>Index</title>
</head>
<body>
<div>
@Model.Name
</div>
</body>
</html>
增加_BasicLayout.cshtml
<!DOCTYPE html>
<html>
<head>
<meta name="viewport" content="width=device-width" />
<title>@ViewBag.Title</title>
</head>
<body>
<div>
<h1>Product Information</h1>
<div style="padding: 20px; border: solid medium black; font-size: 20pt">
@RenderBody()
</div>
<h2>Visit <a href="http://apress.com">Apress</a></h2>
</div>
</body>
</html>
修改view
@model Razor.Models.Product
@{
ViewBag.Title = "Product Name";
Layout = "~/Views/_BasicLayout.cshtml";
}
@Model.Name
页面增加逻辑
@switch ((int)ViewBag.ProductCount)
{
case 0:
@: Out of Stock
break;
case 1:
<b>Low Stock (@ViewBag.ProductCount)</b>
break;
default:
@ViewBag.ProductCount
break;
}
@if (ViewBag.ProductCount == 0)
{
@:Out of Stock
} else if (ViewBag.ProductCount == 1) {
<b>Low Stock (@ViewBag.ProductCount)</b>
}
else
{
@ViewBag.ProductCount
}
