OleDbDataAdapter is used to get the data from an Access database.

To access data from an Access database in a .NET application, you would typically use an OleDbDataAdapter. The OleDbDataAdapter is used to retrieve data from an Access database using the OleDb data provider in .NET. It acts as a bridge between the dataset and the data source, allowing you to fill a dataset with data from the Access database and update changes back to the database if needed.

Here’s a brief explanation of how you would use it:

csharp

using System;

using System.Data;

using System.Data.OleDb;
class Program

{

    static void Main()

    {

        string connectionString = "Provider=Microsoft.ACE.OLEDB.12.0;Data Source=C:\\path\\to\\your\\database.accdb;";

        string query = "SELECT * FROM YourTableName";
        using (OleDbConnection connection = new OleDbConnection(connectionString))

        {

            OleDbDataAdapter adapter = new OleDbDataAdapter(query, connection);
            DataSet dataSet = new DataSet();

            adapter.Fill(dataSet, "YourTableName");

// Now you can work with the data in the dataSet } } }

Replace “YourTableName” with the name of the table you want to retrieve data from, and make sure to adjust the connection string to point to your Access database file.
