asp.net cshtml can't run asp.net code

Question

I'm following the tutorial at asp.net mvc3 at http://www.asp.net/mvc/tutorials/getting-started-with-mvc3-part3-cs

@{
    ViewBag.Title = "Welcome";
}

<h2>Welcome</h2>

<ul> 
   @for (int i=0; i < ViewBag.NumTimes; i++) { 
      <li>@ViewBag.Message</li> 
   } 
</ul>

the hellowWorldcontroller

using System.Web;
using System.Web.Mvc;

namespace MvcApplication1.Controllers
{
    public class HelloWorldController : Controller
    {
        // GET: /HelloWorld/ 

        /*public void Index()
        {
            //return "This is my <b>default</b> action...";
            return View;
        }*/
        public ActionResult Index()
        {
            //ViewBag.Message = "Welcome to ASP.NET MVC!";


            return View();
        }

        // 
        // GET: /HelloWorld/Welcome/ 

        public ActionResult Welcome(string name, int numTimes = 1)
        {
            return View();
            //return HttpUtility.HtmlEncode("Hello " + name + ", NumTimes is: " + numTimes);
        }
    }
}

But it seems that in cshtml, it can't run the asp.net code, only display the static content, why?

And the cshtml also don't apply to the MainContent master page, there is only plain text without any background and button when I run the application, where's the problems?

Because you need to set ViewBag.NumTimes = numTimes; in Welcome action. — hazzik

@hkinterview, for viewbag title to take effect, you need to use it in the markup - for example, <title>@ViewBag.Title</title> in html head section. I guess that it must be located in some layout page. — VinayC

To have your for to work, you must set the value of ViewBag in the controller.

Change the the controller like this

public ActionResult Welcome(string name, int numTimes = 1)
{
    ViewBag.Message = name;
    ViewBag.NumTimes = numTimes;
    return View();
}

how about the master page problem?

Iridio Over a year ago

If you mean the title, it's the same, set ViewBag.Title = "hello". you will find the call in Shared/_layout.cshtml. If you mean the css, in layout check for the correct path of scripts and css

you see this asp.net/mvc/tutorials/getting-started-with-mvc3-part3-cs, the content display in white area, but my application, it only displays the Welcome.cshtml

It should work if you followed the step in the tutorial (and it seems so), maybe your project is broken. Have you tried to make a new MVC3 project from scratch? Maybe you changed something by mistake in the _layout.cshtml.
