      DotNetZip 是一个短小易用的用来操作 zip 文件的 .NET 类库，支持.NET的任何语言，可很方便的创建，读取，和更新zip文件。而且还可以使用在.NETCompact Framework中。

下面是一些简单的例子：


    
      1
    
      .加密压缩：


    
      using
    
       (ZipFile zip 
    
      =
    
       
    
      new
    
       ZipFile()) 
{ 
 zip.Password 
    
      =
    
       sPassword; 
    
      //
    
      set pwd
    
      

    
       zip.AddDirectory(sZipDir); 
 zip.Save(sSavePath 
    
      +
    
       
    
      @"
    
      \
    
      "
    
       
    
      +
    
       sSaveName); 
}


    
      2
    
      .向压缩文件中添加：

    
      using
    
       (ZipFile zip 
    
      =
    
       
    
      new
    
       ZipFile(
    
      "
    
      Backup.zip
    
      "
    
      ))
 {
 zip.Password
    
      =
    
       
    
      "
    
      123456!
    
      "
    
      ;
 zip.AddFile(
    
      "
    
      ReadMe.txt
    
      "
    
      );
 zip.AddFile(
    
      "
    
      7440-N49th.png
    
      "
    
      );
 zip.AddFile(
    
      "
    
      2005_Annual_Report.pdf
    
      "
    
      ); 
 zip.Save();
 }


    
      3
    
      .解压缩到制定目录：

    
      using
    
       (ZipFile zip 
    
      =
    
       ZipFile.Read(
    
      "
    
      D:\\test\\2007.zip
    
      "
    
      ))
{
 
    
      foreach
    
       (ZipEntry e 
    
      in
    
       zip)
 {
 Console.WriteLine(
    
      "
    
      file name:{0}
    
      "
    
      , e.FileName);
 Console.WriteLine(e.Comment);
 e.Extract(
    
      "
    
      D:\\test\\pwdata
    
      "
    
      , 
    
      true
    
      ); 
    
      //
    
       overwrite == true
    
      

    
       }
} 


    
      4
    
      .中文乱码问题 System.Text.Encoding.Default

    
      using
    
       (ZipFile zip 
    
      =
    
       
    
      new
    
       ZipFile(System.Text.Encoding.Default))
{

    
      foreach
    
       (var f 
    
      in
    
       filesToInclude)
{
zip.AddFile(f, 
    
      "
    
      files
    
      "
    
      );
}
zip.AddEntry(
    
      "
    
      Readme.txt
    
      "
    
      , 
    
      ""
    
      , ReadmeText);
zip.Save(Response.OutputStream);
}
