DataAdapter Select Command - Sql Server

OleDbDataAdapter is a part of the ADO.NET Data Provider. OleDbDataAdapter provides the communication between the Dataset and the Data Source with the help of OleDbConnection Object . The OleDbDataAdapter works with the DataSet to provide a disconnected data retrieval mechanism.

The SelectCommand property of the OleDbDataAdapter is a Command object that retrieves data from the data source. The Fill method takes its arguments a DataSet to be populated, and a DataTable object, or the name of the DataTable to be filled with the rows returned from the SelectCommand. The following C# program shows the OleDbDataAdapter using its SelectCommand property to retrieve the data from the Data Source.

    public partial class Form1 : Form
        public Form1()

        private void button1_Click(object sender, EventArgs e)
            string connetionString = null;
            OleDbConnection connection ;
            OleDbDataAdapter oledbAdapter = new OleDbDataAdapter();
            DataSet ds = new DataSet();
            int i = 0;
            connetionString = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=Your mdb filename;";
            connection = new OleDbConnection(connetionString);
                oledbAdapter.SelectCommand = new OleDbCommand("Your SQL Statement Here", connection);
                for (i = 0; i <= ds.Tables[0].Rows.Count - 1; i++)
                    MessageBox.Show (ds.Tables[0].Rows[i].ItemArray[0].ToString());
