Introduction - (ADO.NET Tutorial)

ADO.NET is a set of data access technologies that are included in the .NET framework. It provides a set of libraries and classes for accessing and manipulating data from various data sources like databases, XML documents, and more. ADO.NET is designed to work with .NET languages such as C# and VB.NET.

Syntax

ADO.NET is a set of classes and libraries that are used in .NET application development. To use ADO.NET, you need to learn the syntax of the classes and methods provided by the library. Here is an example of connecting to a SQL Server database using ADO.NET in C#:

using System;
using System.Data.SqlClient;

class Program
{
    static void Main()
    {
        string connectionString = "Data Source=myServerAddress;Initial Catalog=myDataBase;User Id=myUsername;Password=myPassword;"
        SqlConnection connection = new SqlConnection(connectionString);

        try
        {
            connection.Open();
            Console.WriteLine("Connection Open!");
            connection.Close();
        }
        catch (Exception ex)
        {
            Console.WriteLine("Error: " + ex.Message);
        }
    }
}

Example

In the above example, the SqlConnection class is used to create a connection to the database. The Open() method is used to establish a connection to the SQL Server database. The connection string specifies the location of the SQL Server database and other parameters like username and password. The Close() method is used to close the connection after the database operations are completed.

Output

When you run this program, it establishes a connection to the specified SQL Server database and displays the message "Connection Open!" in the console.

Explanation

ADO.NET includes a set of classes and libraries that are used to access and manipulate data from various data sources. ADO.NET is designed to work with .NET languages such as C# and VB.NET, and provides features like data binding, data validation, and data caching.

Use

ADO.NET is used to access and manipulate data from various data sources like databases, XML documents, and more. ADO.NET provides the following benefits:

  • Provides a set of classes and libraries for accessing and manipulating data from various data sources.
  • Supports various types of databases like SQL Server, Oracle, MySQL, and more.
  • Provides features like data binding, data validation, and data caching.
  • Integrates well with other .NET technologies.
