asp.net用代码压缩服务器上文件夹或文件

实现过程

）先引用ICSharpCodeSharpZipLibdll

）cs文件引入

usingSystemIO;
usingSystemText;

usingICSharpCodeSharpZipLibChecksums;
usingICSharpCodeSharpZipLibZip;
usingICSharpCodeSharpZipLibGZip;

）代码

#region下列代码为压缩并下载代码
ZipOutputStreamzos=null;
StringstrBaseDir="";

voiddlZipDir(stringstrPathstringstrFileName)
{
MemoryStreamms=null;
ResponseContentType="application/octetstream";
strFileName=HttpUtilityUrlEncode(strFileName)Replace(’+’’’);
ResponseAddHeader("ContentDisposition""attachment;filename="+strFileName+"zip");
ms=newMemoryStream();
zos=newZipOutputStream(ms);
strBaseDir=strPath+"";
addZipEntry(strBaseDir);
zosFinish();
zosClose();
ResponseClear();
ResponseBinaryWrite(msToArray());
ResponseEnd();
}
