        </div>
        <h2>Visit <a href="http://apress.com">Apress</a></h2>
    </div>
</body>
</html>

修改view

@model Razor.Models.Product

@{

    Layout = "~/Views/_BasicLayout.cshtml";
}

@Model.Name

Razor小案例_html

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
}
