{
    static void Main()
    {
        using (var connection = new SqlConnection("YourConnectionString"))
        {
            connection.Open();

            // Use ReadCommitted to prevent dirty reads
            using (var transaction = connection.BeginTransaction(IsolationLevel.ReadCommitted))
            {
                try
                {
                    // Sample database operation
                    using (var command = new SqlCommand("SELECT * FROM YourTable", connection, transaction))
                    {
                        var reader = command.ExecuteReader();
                        while (reader.Read())
                        {
                            Console.WriteLine(reader["YourColumn"]);
                        }
                    }

                    // Commit the transaction
                    transaction.Commit();
                }
                catch (Exception ex)
                {
                    // Rollback if there's an error
                    transaction.Rollback();
                    Console.WriteLine($"Error: {ex.Message}");
                }
            }
        }
    }
}

🔍 Highlights:

• Read Uncommitted: Allows dirty reads 🥴
• Read Committed: Prevents dirty reads ✅
• Repeatable Read: Locks data for reading 🔒
• Serializable: Highest level of isolation 🏆

Choose wisely to balance performance and consistency!
