c# 压缩 解压 7z

利用7z.dll进行压缩和解压代码如下：

using System;

using SevenZip.Sdk;

using SevenZip.Sdk.Compression;

using SevenZip;

using System.IO;

 

namespace DCRM.Common

{

     

    public class CompressorHelper

    {

        public static void Compressor(string p_7zdllPath,string compressDicrectoryName)

        {

            SevenZipCompressor.SetLibraryPath(p_7zdllPath);

            SevenZipCompressor tmp = new SevenZipCompressor();

            string fileName=Path.GetDirectoryName(compressDicrectoryName)+".7z";

            tmp.CompressDirectory(compressDicrectoryName,fileName);

        }

         

        public static void UnCompressor(string p_7zdllPath,string compressFilesFullName,string des)

        {

            SevenZipExtractor.SetLibraryPath(p_7zdllPath);

            using (SevenZipExtractor tmp = new SevenZipExtractor(compressFilesFullName))

            {

                for (int i = 0; i < tmp.ArchiveFileData.Count; i++)

                {

                    tmp.ExtractFiles(des, tmp.ArchiveFileData[i].Index);

                }

                 

            }

  

        }

    }

}
