asp.net实现文件夹及文件压缩，并实现下载

步骤

）先引用 ICSharpCode SharpZipLib dll

） cs文件引入

using System IOusing System Text

using ICSharpCode SharpZipLib Checksumsusing ICSharpCode SharpZipLib Zipusing ICSharpCode SharpZipLib GZip

）代码

#region 下列代码为压缩并下载代码        ZipOutputStream zos = null       String strBaseDir = ""

       void dlZipDir(string strPath string strFileName)        {            MemoryStream ms = null           Response ContentType = "application/octet stream"           strFileName = HttpUtility UrlEncode(strFileName) Replace( + )           Response AddHeader("Content Disposition" "attachment   filename=" + strFileName + " zip")           ms = new MemoryStream()           zos = new ZipOutputStream(ms)           strBaseDir = strPath + ""           addZipEntry(strBaseDir)           zos Finish()           zos Close()           Response Clear()           Response BinaryWrite(ms ToArray())           Response End()       }

将文件批量压缩，使用zipfile库。一幅厚颜无耻的漫画。

以下代码可以将文件批量压缩：importos；importzipfile；fromrandomimportrandrange；defzip_dir(path,zip_handler):forroot,dirs,filesinos.walk(path):forfileinfiles:zip_handler.write(os.path.join(root,file))；if__name__=='__main__':to_zip=input("""Enterthenameofthefolderyouwantto(N.B.:Thefoldernameshouldnotcontainblankspaces)>""")to_zip=to_zip.strip()+"/"zip_file_name=f'zip{randrange(0,10000)}.zip'zip_file=zipfile.ZipFile(zip_file_name,'w',zipfile.ZIP_DEFLATED)zip_dir(to_zip,zip_file)zip_file.close()print(f'FileSavedas{zip_file_name}')。输入下面这行代码，你会跳转到一个漫画网页：>>importantigravity
