为多个文件创建zip，然后将其上传到文件夹中

本文关键字：文件夹 然后 文件创建 zip | 更新日期: 2023-09-27 17:49:36

我想将zip文件保存到服务器上，只有一个以上的文件。首先，它应该创建一个zip文件，然后上传到文件夹

    if (FileUpload1.HasFile)
    {
        string fileName = Path.GetFileName(FileUpload1.PostedFile.FileName);
        string fileLocation = Server.MapPath("~/uploads/" + fileName);
        FileUpload1.SaveAs(fileLocation);

        ZipFile createZipFile = new ZipFile();
        createZipFile.AddFile(fileLocation, string.Empty);
        createZipFile.Save(Server.MapPath("~/uploads/CsharpAspNetArticles.zip"));
    }

如果我理解你的"noquestion"问题:)你应该像这样使用IHttpHandler:

using System;
using System.IO;
using System.Web;
using ICSharpCode.SharpZipLib.Zip;
public class ZipHandler : IHttpHandler
{
    public bool IsReusable
    {
        get { return true; }
    }
    public void ProcessRequest(HttpContext ctx)
    {
        var path = HttpUtility.UrlDecode(ctx.Request.QueryString["folder"]);
        if (path == null)
        {
            return;
        }
        var folderName = Path.GetFileName(path);
        if (folderName == String.Empty)
        {
            folderName = "root";
        }
        int folderOffset = ctx.Server.MapPath("~").Length;
        using (var zipStream = new ZipOutputStream(ctx.Response.OutputStream))
        {
            ctx.Response.Clear();
            ctx.Response.BufferOutput = false;
            ctx.Response.AddHeader("Content-Disposition", "attachment; filename=" + folderName + ".zip");
            ctx.Response.AddHeader("Content-Type", "application/zip");
            zipStream.SetLevel(3);
            CompressFolder(path, zipStream, folderOffset);
            ctx.Response.Flush();
        }
    }
    private static void CompressFolder(string path, ZipOutputStream zipStream, int folderOffset)
    {
        string[] files = Directory.GetFiles(path);
        foreach (string filename in files)
        {
            try
            {
                using (var streamReader = File.OpenRead(filename))
                {
                    var fi = new FileInfo(filename);
                    string entryName = filename.Substring(folderOffset);
                    entryName = ZipEntry.CleanName(entryName);
                    var newEntry = new ZipEntry(entryName)
                    {
                        DateTime = fi.LastWriteTime,
                        Size = fi.Length
                    };
                    zipStream.PutNextEntry(newEntry);
                    streamReader.CopyTo(zipStream, 4096);
                    zipStream.CloseEntry();
                }
            }
            catch (IOException) { }
        }
        var folders = Directory.GetDirectories(path);
        foreach (string folder in folders)
        {
            CompressFolder(folder, zipStream, folderOffset);
        }
    }
}
