Introduction

ASP.NET is a popular programming language used for developing web applications. It provides a framework for building websites, web services, and web applications. In this article, we will explore the ASP.NET programming language and provide examples to help you understand its usage.

Getting Started with ASP.NET

To begin with ASP.NET programming, you need to have a understanding of C# language. ASP.NET is built on top of the C# language and uses its and features. If you are new to C#, it is recommended to learn the basics of C# before diving into ASP.NET.

Let's start with a simple of an ASP.NET web application. We will create a basic “Hello World” application that displays a greeting message on a web page.


using System;
using System.Web.UI;

namespace HelloWorld
{
    public partial class Default : Page
    {
        protected void Page_Load(object sender, EventArgs e)
        {
            Response.Write("Hello, World!");
        }
    }
}

In the above example, we have created a new ASP.NET web application named “HelloWorld”. The code is written in C# and is contained within a class named “Default” which inherits from the “Page” class provided by ASP.NET.

The “Page_Load” method is an event handler that gets executed when the web page loads. In this method, we use the “Response.Write” method to display the greeting message “Hello, World!” on the web page.

ASP.NET Web Forms

ASP.NET Web Forms is a part of the ASP.NET framework that allows you to build web applications using a drag-and-drop approach. It provides a set of server controls that can be placed on a web page and manipulated using code-behind .

Let's consider an example where we create a simple registration form using ASP.NET Web Forms.







    Registration Form


    


In the above example, we have an ASP.NET web form named “Registration.aspx”. It contains various server controls such as TextBox and Button. The code-behind file “Registration.aspx.cs” contains the event handler for the button click event.

When the user clicks the “” button, the “btnSubmit_Click” event handler is executed. You can write code in this event handler to perform actions such as validating user input and saving data to a database.

ASP.NET MVC

ASP.NET MVC is a framework within ASP.NET that follows the -View-Controller architectural pattern. It provides a structured way to build web applications by separating the concerns of data, presentation, and user interaction.

Let's consider an example where we create a simple ASP.NET MVC application that displays a list of products.


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

namespace MvcApplication.Controllers
{
    public class ProductController : Controller
    {
        public  Index()
        {
            List products = new List
            {
                "Product 1",
                "Product 2",
                "Product 3"
            };

            return View(products);
        }
    }
}

In the above example, we have a controller named “ProductController” that inherits from the “Controller” class provided by ASP.NET MVC. The “Index” action method returns a list of products to the corresponding view.

The corresponding view file “Index.cshtml” can be created with the following code:


@model List




    Product List


    

Product List

    @foreach (var product in Model) {
  • @product
  • }

In the above view file, we use the “@model” to specify the type of the model from the controller. We then iterate over the list of products using a foreach loop and display them as list items.

Conclusion

ASP.NET is a powerful programming language for building web applications. In this article, we explored the basics of ASP.NET programming and provided examples to help you understand its usage. Whether you choose ASP.NET Web Forms or ASP.NET MVC, ASP.NET provides a robust framework for developing web applications.
