任何人都可以帮助我如何将文件夹转换为经典 asp 中的 zip 文件。

<% 
Dim objZip 
Response.write("new") 
Set objZip = Server.CreateObject("Scripting.FileSystemObject") 
Response.write("yahoo") 
objZip.Pack "C:\inetpub\wwwroot\NewZIp\Images\SMM.JPEG", "C:\inetpub\wwwroot\NewZIp\Images.zip" 
objZip.Pack "C:\inetpub\wwwroot\NewZIp\Images\IMS.JPEG", "C:\inetpub\wwwroot\NewZIp\Images.zip" 
Set objZip = Nothing 
%> 

我正在使用这个代码将文件夹转换为 zip

Answer 1

这可以使用 C# 在 asp.net 中轻松完成。以下代码将帮助您压缩文件夹。

using System;
using System.IO;
using System.IO.Packaging;

namespace ZipSample
{
    class Program
    {
        static void Main(string[] args)
        {
            AddFileToZip("Output.zip", @"C:\Windows\ABC.exe");
            AddFileToZip("Output.zip", @"C:\Windows\System32\DEF.exe");
        }

        private const long BUFFER_SIZE = 4096;

        private static void AddFileToZip(string zipFilename, string fileToAdd)
        {
            using (Package zip = System.IO.Packaging.Package.Open(zipFilename, FileMode.OpenOrCreate))
            {
                string destFilename = ".\\" + Path.GetFileName(fileToAdd);
                Uri uri = PackUriHelper.CreatePartUri(new Uri(destFilename, UriKind.Relative));
                if (zip.PartExists(uri))
                {
                    zip.DeletePart(uri);
                }
                PackagePart part = zip.CreatePart(uri, "",CompressionOption.Normal);
                using (FileStream fileStream = new FileStream(fileToAdd, FileMode.Open, FileAccess.Read))
                {
                    using (Stream dest = part.GetStream())
                    {
                        CopyStream(fileStream, dest);
                    }
                }
            }
        }

        private static void CopyStream(System.IO.FileStream inputStream, System.IO.Stream outputStream)
        {
            long bufferSize = inputStream.Length < BUFFER_SIZE ? inputStream.Length : BUFFER_SIZE;
            byte[] buffer = new byte[bufferSize];
            int bytesRead = 0;
            long bytesWritten = 0;
            while ((bytesRead = inputStream.Read(buffer, 0, buffer.Length)) != 0)
            {
                outputStream.Write(buffer, 0, bytesRead);
                bytesWritten += bufferSize;
            }
        }
    }
}
