C#实现将文件、文件夹压缩为压缩包
一、C#实现将文件、文件夹压缩为压缩包核心
1、介绍
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
2、代码

二、使用方法
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");
