}总结与最佳实践
本章重点回顾
在本章中，我们深入学习了工作簿与工作表的基础操作：
- 工作簿操作：创建、打开、保存、属性管理、状态监控
- 工作表管理：创建、复制、隐藏、保护、导航
- 实战应用：企业报表系统的完整实现
- 性能优化：资源管理、内存优化、错误处理
核心知识点总结
工作簿操作要点
- 创建方式：空白工作簿、基于模板、打开现有文件
- 保存策略：常规保存、增量保存、备份保存、自动保存
- 属性管理：内置属性、自定义属性、文档元数据
- 资源管理：正确的Dispose模式、内存泄漏预防
工作表操作要点
- 创建管理：添加、删除、重命名、移动、复制
- 可见性控制：可见、隐藏、深度隐藏
- 保护机制：密码保护、权限设置、区域保护
- 导航技术：激活、选择、遍历、状态管理
最佳实践指南
代码组织最佳实践

// 推荐：使用面向对象的设计

{

{
// 初始化工作簿
using var excelApp = ExcelFactory.BlankWorkbook();
_workbook = excelApp.ActiveWorkbook;
}
public void GenerateReport()
{
try
{
CreateCoverPage();
CreateBalanceSheet();
CreateIncomeStatement();
CreateAnalysis();
// 统一保存
SaveReport();
}
catch (Exception ex)
{
HandleError(ex);
}
}
// 具体的创建方法...
}错误处理最佳实践
csharp
public class SafeWorkbookOperation
{
public void PerformOperation()
{
IExcelApplication excelApp = null;
try
{

// 执行操作
var workbook = excelApp.ActiveWorkbook;
// ... 操作代码
