参考代码 C# 将多个文件打包压缩成一个ZIP文件包 www.youwenfan.com/contentcnv/116275.html
三、功能特点
多文件打包：支持将多个文件和文件夹打包成一个ZIP文件
密码保护：支持为ZIP文件设置密码（使用 SharpZipLib）
压缩级别控制：无压缩、最快压缩、最佳压缩三种级别
进度监控：实时显示压缩进度和当前处理的文件
取消操作：支持中途取消压缩操作
文件夹压缩：支持压缩整个文件夹及其子文件夹
解压功能：支持解压ZIP文件到指定目录
文件过滤：支持按文件类型筛选要压缩的文件
覆盖控制：可选择是否覆盖已存在的输出文件
四、使用说明
4.1 基本使用
- 运行程序，点击"选择文件"或"选择文件夹"添加要压缩的内容
- 设置输出文件路径和压缩选项
- 点击"压缩"按钮开始压缩
4.2 高级功能
- 密码保护：在密码框中输入密码，生成的ZIP文件将需要密码才能解压
- 包含基目录：勾选此项将在ZIP中保留文件夹结构
- 覆盖已有文件：勾选此项将覆盖同名的输出文件
4.3 批量操作
- 可以同时选择多个文件和文件夹进行压缩
- 支持拖拽文件到程序窗口（需要扩展代码）
4.4 注意事项
- 使用 .NET 内置的
ZipFile类不支持密码保护 - 如果需要密码保护，请使用 SharpZipLib 版本
- 大文件压缩可能需要较长时间，请耐心等待
