ASP — ASP.NET MVC

MVC Pattern

• Model: Data and business logic
• View: User interface
• Controller: Handles requests

Controller

public class HomeController : Controller
{
    public ActionResult Index()
    {
        return View();
    }
    
    public ActionResult About()
    {
        ViewBag.Message = "About page";
        return View();
    }
}

View

@{
    ViewBag.Title = "Home";
}

<h1>Welcome to ASP.NET MVC</h1>
<p>@ViewBag.Message</p>

Model

public class User
{
    public int Id { get; set; }
    public string Name { get; set; }
    public string Email { get; set; }
}

Razor Syntax

@model MyApp.Models.User

<h1>@Model.Name</h1>

@if (Model.IsActive)
{
    <span>Active</span>
}

@foreach (var item in Model.Items)
{
    <li>@item.Name</li>
}
