Title“基础工具” 项目压缩包帮助类 Description步骤描述 1、创建 zip 存档该文档包含指定目录的文件和子目录单个目录 2、创建 zip 存档该存档包含指定目录的文件和目录多个目录 3、递归删除磁盘上的指定文件夹目录及文件 4、递归获取磁盘上的指定目录下所有文件的集合返回类型是字典[文件名要压缩的相对文件名] 5、解压Zip文件并覆盖保存到指定的目标路径文件夹下 6、获取Zip压缩包中的文件列表

①引用命名空间
using Utils.Zip;②实例化压缩帮助类然后调用方法即可,如下所示将文件夹压缩为一个压缩包
//实例化压缩帮助类ZipHelper zipHelper new ZipHelper();
//调用创建压缩包的方法zipHelper.CreatZip(C:\Software\Test, D:\Document\ZipPackage\updatePackage.zip);
