asp.net mvc - What does the "@" in ASP MVC mean/do?

Question

I know this is a simple question, but I am new to ASP MVC and just can't find the answer to this anywhere - what is the "@" that I am seeing everywhere? example:

@{
    ViewBag.Title = "Welcome";
}

<h2>Welcome</h2>

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

Answer 1

@ is a syntax element of Razor engine, that is used in ASP.NET MVC 3. Your code will show text from ViewBag.Message ViewBag.NumTimes times.

ViewBag properties are dynamic and can be populated from controller.
