一、FileZilla
Filezilla分为client和server。其中FileZilla Server是Windows平台下一个小巧的第三方FTP服务器软件，系统资源也占用非常小，可以让你快速简单的建立自己的FTP服务器。
打开FileZilla，进行如下操作
下图红色区域就是linux系统的文件目录，可以直接把windows下的文件直接拖拽进去。
二、WinSCP
跟FileZilla一样，也是一款十分方便的文件传输工具。WinSCP是连接Windows和Linux的。
WinSCP .NET Assembly and SFTP
https://winscp.net/eng/docs/library#csharp
// Setup session options
SessionOptions sessionOptions = new SessionOptions
{
Protocol = Protocol.Sftp,
HostName = "example.com",
UserName = "user",
Password = "mypassword",
SshHostKeyFingerprint = "ssh-rsa 2048 xxxxxxxxxxx...="
};
using (Session session = new Session())
{
// Connect
session.Open(sessionOptions);
// Upload files
TransferOptions transferOptions = new TransferOptions();
transferOptions.TransferMode = TransferMode.Binary;
TransferOperationResult transferResult;
transferResult = session.PutFiles(@"d:\toupload\*", "/home/user/", false, transferOptions);
// Throw on any error
transferResult.Check();
// Print results
foreach (TransferEventArgs transfer in transferResult.Transfers)
{
Console.WriteLine("Upload of {0} succeeded", transfer.FileName);
}
}三、FluentFTP
FluentFTP是一款老外开发的基于.Net的支持FTP及的FTPS 的FTP类库，FluentFTP是完全托管的FTP客户端，被设计为易于使用和易于扩展。它支持文件和目录列表，上传和下载文件和SSL / TLS连接。
它底层由Socket实现，可以连接到Unix和Windows IIS建立FTP的服务器，

举例：
// create an FTP client
FtpClient client = new FtpClient("123.123.123.123");
// if you don't specify login credentials, we use the "anonymous" user account
client.Credentials = new NetworkCredential("david", "pass123");
// begin connecting to the server
client.Connect();
// get a list of files and directories in the "/htdocs" folder
foreach (FtpListItem item in client.GetListing("/htdocs")) {
// if this is a file
if (item.Type == FtpFileSystemObjectType.File){
// get the file size
long size = client.GetFileSize(item.FullName);
}
// get modified date/time of the file or folder
DateTime time = client.GetModifiedTime(item.FullName);
// calculate a hash for the file on the server side (default algorithm)
FtpHash hash = client.GetHash(item.FullName);
}
// upload a file
client.UploadFile(@"C:\MyVideo.mp4", "/htdocs/big.txt");
// rename the uploaded file
client.Rename("/htdocs/big.txt", "/htdocs/big2.txt");
// download the file again
client.DownloadFile(@"C:\MyVideo_2.mp4", "/htdocs/big2.txt");
// delete the file
client.DeleteFile("/htdocs/big2.txt");
// delete a folder recursively
client.DeleteDirectory("/htdocs/extras/");
// check if a file exists
if (client.FileExists("/htdocs/big2.txt")){ }
// check if a folder exists
if (client.DirectoryExists("/htdocs/extras/")){ }
// upload a file and retry 3 times before giving up
client.RetryAttempts = 3;
client.UploadFile(@"C:\MyVideo.mp4", "/htdocs/big.txt", FtpExists.Overwrite, false, FtpVerify.Retry);
// disconnect! good bye!
client.Disconnect();对FluentFTP部分操作封装类
