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);
				}
				
			}
 
		}
	}
}
