asp.net压缩,解压缩

首先 需要下载DotNetZip的组件

http://dotnetzip.codeplex.com/

在项目中引入Ionic.Zip

引入名字空间

using System.Text;
using Ionic.Zip;

压缩

public static void zipDir(string source,string target)
        {
            //source d:test
            //target d:/mytest.zip
            using (ZipFile zip = new ZipFile(Encoding.UTF8))
            {
                zip.AddDirectory(source);
                zip.Save(target);
            }
        }

解压缩

public static void enZip(string source, string target)
        {
            //source "d:/Archive.zip"  target"d:/newtest"
            using (ZipFile zip = ZipFile.Read(source))
           {
                zip.ExtractAll(target);
            }
        }

 要使用密码的话 zip.Password = "123456";
