基于流的上传：
要通过流上传二进制文件，请使用 FtpWebRequest：
FtpWebRequest request = (FtpWebRequest)WebRequest.Create("ftp://ftp.example.com/remote/path/file.zip");
request.Credentials = new NetworkCredential("username", "password");
request.Method = WebRequestMethods.Ftp.UploadFile;
using (Stream fileStream = File.OpenRead(@"C:\local\path\file.zip"))
using (Stream ftpStream = request.GetRequestStream())
{
fileStream.CopyTo(ftpStream);
}基于流的下载：
对于流式下载，请使用 FtpWebRequest：
FtpWebRequest request = (FtpWebRequest)WebRequest.Create("ftp://ftp.example.com/remote/path/file.zip");
request.Credentials = new NetworkCredential("username", "password");
request.Method = WebRequestMethods.Ftp.DownloadFile;
using (Stream ftpStream = request.GetResponse().GetResponseStream())
using (Stream fileStream = File.Create(@"C:\local\path\file.zip"))
{
ftpStream.CopyTo(fileStream);
}以上是如何在C#中使用流式传输通过FTP上传和下载文件？的详细内容。更多信息请关注PHP中文网其他相关文章！
