c#上传不了文件到ftp服务器,压缩目录并上传到FTP服务器而不在C＃中本地保存.zip文件...

在MemoryStream中创建ZIP存档并上传。

using (Stream memoryStream = new MemoryStream())

{

using (var archive = new ZipArchive(memoryStream, ZipArchiveMode.Create, true))

{

foreach (string path in Directory.EnumerateFiles(@"C:\source\directory"))

{

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);

FtpWebRequest request =

(FtpWebRequest)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需要可搜索的流。如果不是，您将能够直接写入FTP请求流，而不需要将整个ZIP文件保存在内存中。
