.Net视图机制

.Net会有默认的约定。

HomeController下面的Index，会默认渲染Home/Index.cshtml。

当然可以设置成别的，比如设置成About。

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.Mvc;

namespace mvcDemo.Controllers
{
    public class HomeController : Controller
    {
        public ActionResult Index()
        {
            ViewBag.Message = "I like milk.";
            return View("About");
        }

        public ActionResult About()
        {
            ViewBag.Message = "I like cake.";

            return View();
        }

        public ActionResult Contact()
        {
            ViewBag.Message = "Your contact page.";

            return View();
        }
    }
}

这样首页就使用了About的视图页面了。

视图被控制器渲染，控制器提供视图数据，这是.Net约定俗成的。

改为完整路径，

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.Mvc;

namespace mvcDemo.Controllers
{
    public class HomeController : Controller
    {
        public ActionResult Index()
        {
            ViewBag.Message = "I like milk.";
            return View("~/Views/Home/About.cshtml");
        }

        public ActionResult About()
        {
            ViewBag.Message = "I like cake.";

            return View();
        }

        public ActionResult Contact()
        {
            ViewBag.Message = "Your contact page.";

            return View();
        }
    }
}
