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:
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.
