Just wanted to add a class="myClass" in body tag. Is there any html helper or something else can do this in MVC3 view page? Please advise, thanks.

Generally, you can put your c# code wherever you want. The only conventions that MVC adheres to by default are the Controllers and Views folder.
The _ViewStart. cshtml can also be created in the sub-folders of the View folder to set the default layout page for all the views included in that particular subfolder. For example, the following _ViewStart. cshtml in the Home folder sets the Layout property to _myLayoutPage.
@section is for defining a content are override from a shared view. Basically, it is a way for you to adjust your shared view (similar to a Master Page in Web Forms).
A view is an HTML template with embedded Razor markup. Razor markup is code that interacts with HTML markup to produce a webpage that's sent to the client. In ASP.NET Core MVC, views are .cshtml files that use the C# programming language in Razor markup.
This is very similar to Aaron's solution, but doesn't have the weight of a section (which at least in my mind, are for larger blocks of content than a single string). The simplest way is to pass a variable with the ViewBag.
In your layout, just print out the class for the body tag, plus any other page specific variables (page title, extra css/js scripts, etc...)
_Layout.cshtml:
<html>
<title>@ViewBag.Title</title>@* Can easily add in per page titles too *@
<body class="@ViewBag.BodyClass">
@RenderBody()
</body>
</html>
Then, variables set in your view get passed upwards to the layout:
Index.cshtml:
@model MyViewModel
@{
ViewBag.Title = "This page title!";
ViewBag.BodyClass = "...";
}
