問題描述

我的問題是標題.我試過這個:

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);
}

錯誤:

System.NotSupportedException:不支持路徑格式."

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

我不知道在這種情況下我應該如何連接到 FTP 服務器并將目錄壓縮到 ram 中并將其直接發送到服務器.

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.

...有人可以提供幫助或提供指向類似或相同問題的鏈接嗎?解決了什么?

... can someone help or have a link to a similar or equal problem what was solved?

推薦答案

在MemoryStream中創建ZIP壓縮包并上傳.

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 需要一個可搜索的流.如果不是這樣，您將能夠直接寫入 FTP 請求流，而無需將整個 ZIP 文件保存在內存中.

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 在內存中創建 ZIP 存檔
• 將文件從字符串或流上傳到 FTP 服務器
