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);
                                }
                                
                        }
 
                }
        }
}
