压缩目录并上传到 FTP 服务器，而无需在 C# 中本地保存 .zip 文件 [英] Zip a directory and upload to FTP server without saving the .zip file locally in C#

问题描述

我的问题是标题.我试过这个:

My question is the title. I have tried this:

public void UploadToFtp(List<strucProduktdaten> ProductData)
{
    ProductData.ForEach(delegate( strucProduktdaten data )
    {
        ZipFile.CreateFromDirectory(data.Quellpfad, data.Zielpfad, CompressionLevel.Fastest, true);
    });
}


static void Main(string[] args)
{
    List<strucProduktdaten> ProductDataList = new List<strucProduktdaten>();
    strucProduktdaten ProduktData = new strucProduktdaten();
    ProduktData.Quellpfad = @"Path	ozip";
    ProduktData.Zielpfad = @"Link to the ftp"; // <- i know the link makes no sense without a connect to the ftp with uname and password

    ProductDataList.Add(ProduktData);

    ftpClient.UploadToFtp(ProductDataList);
}

错误:

System.NotSupportedException:不支持路径格式."

System.NotSupportedException:"The Path format is not supported."

我不知道在这种情况下我应该如何连接到 FTP 服务器并将目录压缩到 ram 中并将其直接发送到服务器.

I have no idea how I should connect in this case to the FTP server and zipping the directory in ram and send it directly to the server.

...有人可以提供帮助或提供指向类似或相同问题的链接吗?解决了什么?

推荐答案

在MemoryStream中创建ZIP压缩包并上传.

Create the ZIP archive in MemoryStream and upload it.

using (Stream memoryStream = new MemoryStream())
{
    using (var archive = new ZipArchive(memoryStream, ZipArchiveMode.Create, true))
    {
        foreach (string path in Directory.EnumerateFiles(@"C:sourcedirectory"))
        {
            ZipArchiveEntry entry = archive.CreateEntry(Path.GetFileName(path));

            using (Stream entryStream = entry.Open())
            using (Stream fileStream = File.OpenRead(path))
            {
                fileStream.CopyTo(entryStream);
            }
        }
    }

    memoryStream.Seek(0, SeekOrigin.Begin);

    var request =
        WebRequest.Create("ftp://ftp.example.com/remote/path/archive.zip");
    request.Credentials = new NetworkCredential("username", "password");
    request.Method = WebRequestMethods.Ftp.UploadFile;
    using (Stream ftpStream = request.GetRequestStream())
    {
        memoryStream.CopyTo(ftpStream);
    }
}

不幸的是，ZipArchive 需要一个可搜索的流.如果不是这样，您将能够直接写入 FTP 请求流，而无需将整个 ZIP 文件保存在内存中.

Unfortunately the ZipArchive requires a seekable stream. Were it not, you would be able to write directly to the FTP request stream and won't need to keep a whole ZIP file in a memory.

基于:

• 使用 System.IO.Compression 在内存中创建 ZIP 存档
• 将文件从字符串或流上传到 FTP 服务器
