Asp net core application with ado net example


ASP.NET is a popular language used for building web applications. It provides a framework for developing dynamic , web services, and web applications. One of the key features of ASP.NET is its ability to interact with databases ADO.NET.

What is ADO.NET?

ADO.NET is a data access technology provided by Microsoft that allows developers to interact with databases. It provides a set of classes and libraries that enable developers to connect to databases, retrieve data, and various operations on the data.

Creating an ASP.NET Core Application with ADO.NET

To demonstrate how to use ADO.NET in an ASP.NET Core application, let's consider an example of a simple web application that retrieves data from a database and displays it on a web page.

First, let's create a new ASP.NET Core application. Open Visual Studio and select “Create a new project.” Choose the ASP.NET Core Web Application template and give your project a name.

Once the project is created, open the “.cs” file and add the necessary configuration to connect to the database. This typically involves specifying the connection string, which contains information about the database server, database name, and authentication details.

public void (IServiceCollection services)
    // Add database connection
    services.AddDbContext( =>

Creating a Data Model

Next, let's create a data model that represents the table in the database we want to retrieve data from. This can be done by creating a new class and defining properties that correspond to the columns in the table.

public class 
    public int Id { get; set; }
    public string Name { get; set; }
    public decimal Price { get; set; }

Retrieving Data from the Database

Now that we have our data model, let's retrieve data from the database using ADO.NET. In the controller class, create an of the database context and use it to query the database and retrieve the desired data.

public  Index()
    List products = new List();

    using (var context = new ApplicationDbContext())
        products = context.Products.ToList();

    return View(products);

Displaying Data on a Web Page

Finally, let's display the retrieved data on a web page. In the view file, iterate over the list of products and display the relevant information.

@model List

@foreach (var product in Model)

@product.Name - $@product.Price



Using ADO.NET in an ASP.NET Core application allows developers to interact with databases and retrieve data. By following the steps outlined in this article, you can create a simple web application that retrieves data from a database and displays it on a web page.
