如何从只包含选定列的Access数据库填充我的DataGridView？

using System.Data.OleDb;
using System.Windows.Forms;

// 连接到Access数据库
string connectionString = "Provider=Microsoft.ACE.OLEDB.12.0;Data Source=数据库文件路径.accdb";
using (OleDbConnection connection = new OleDbConnection(connectionString))
{
    connection.Open();

    // 执行查询语句
    string query = "SELECT 列名1, 列名2 FROM 表名";
    using (OleDbCommand command = new OleDbCommand(query, connection))
    {
        // 执行查询并获取结果
        using (OleDbDataReader reader = command.ExecuteReader())
        {
            // 填充DataGridView
            while (reader.Read())
            {
                // 逐行读取查询结果并添加到DataGridView中
                dataGridView1.Rows.Add(reader["列名1"], reader["列名2"]);
            }
        }
    }
}
