压缩文件

一：使用DotNetZip(文件名含有中文，出现乱码，暂无解决)
.dll文件下载http://www.codeplex.com/DotNetZip/Release/ProjectReleases.aspx?ReleaseId=12712

 

public void CompressWholeFolder( string FromDirectory, string ToDirectory, string ZipName )
    {
        if( Directory.Exists( FromDirectory ) )
        {
            using( ZipFile zip = new ZipFile( ToDirectory + "\\" + ZipName ))
            {
                DirectoryInfo directInfo = new DirectoryInfo( FromDirectory );
                FileSystemInfo[] FilesInfo = directInfo.GetFileSystemInfos();
                //zip.Password = "123";//压缩密码
                
                zip.Comment = "备份文件！";//压缩文件的信息说明
                foreach( FileSystemInfo file in FilesInfo )
                {
                    if( file is FileInfo )
                    {               
                        zip.AddFile( ( file.FullName.ToString()) );//添加文件
                    }              
                    if( file is DirectoryInfo )
                    {
                        zip.AddDirectory( file.FullName );//添加文件夹
                    }            
                }               
                zip.Save();               
            }
        }       
    }

 

 二：调用winrar压缩

using System.Diagnostics;

    /// </summary>
    /// <param name="patch">被压缩文件路径</param>
    /// <param name="rarPatch">压缩文件存放路径</param>
    /// <param name="rarName">设置要压缩的rar名称</param>
    public static bool DoRAR( string patch, string rarPatch, string rarName )
    {
        String WinRAR;
        RegistryKey Reg;
        Object Obj;
        String CmdCommand;
        ProcessStartInfo ProStart;
        Process Pro;
        try
        {
            Reg = Registry.ClassesRoot.OpenSubKey( "Applications\\WinRAR.exe\\Shell\\Open\\Command" );
            Obj = Reg.GetValue( "" );
            WinRAR = Obj.ToString();
            Reg.Close();
            WinRAR = WinRAR.Substring( 1, WinRAR.Length - 7 );
            
            //命令参数

            // -ao 之压缩具有存档属性的文件
            // -df 压缩后删除源文件
            // -ed 压缩时不添加空目录
            // -hp 加密数据及头文件
            // -p 压缩密码

            // -ep  压缩文件去掉文件夹中路径，使所有文件压缩在一个文件夹下
            // -ep1 设置将所有 tmp 文件夹内的全部文件和文件夹加入到压缩文件 test，但是在压缩的路径名不包含「tmp\」WinRAR a -r -ep1 test tmp\*
            // -ep2 当压缩时存储完整的文件路径 (除了驱动器号与前缀的反斜线)

            // 开关 -SFX[名称] - 创建自解压文件
