如何计算c#.net中oledbconnection中的总行数

using System;
using System.Data.OleDb;

class Program
{
    static void Main()
    {
        string connectionString = "Provider=Microsoft.ACE.OLEDB.12.0;Data Source=C:\\path\\to\\database.accdb;";
        string query = "SELECT COUNT(*) FROM TableName";

        using (OleDbConnection connection = new OleDbConnection(connectionString))
        {
            connection.Open();

            using (OleDbCommand command = new OleDbCommand(query, connection))
            {
                int rowCount = (int)command.ExecuteScalar();
                Console.WriteLine("Total row count: " + rowCount);
            }

            connection.Close();
        }
    }
}
