A commonly used open source SFTP library for .NET is SSH.NET.
.NET 的常用开源 SFTP 库是SSH.NET。
With it, you can use a code like this:
有了它，你可以使用这样的代码：
Dim client As SftpClient = New SftpClient("example.com", "username", "password")
client.Connect()
Using stream As Stream = File.OpenRead("C:\local\path\some.csv")
client.UploadFile(stream, "/remote/path/some.csv")
End Using
There are other libraries too. If you need more high-level functions, like uploading all files in a directory or even complete directory structures, you may find myWinSCP .NET assemblyuseful.
还有其他图书馆。如果您需要更多高级功能，例如上传目录中的所有文件甚至完整的目录结构，您可能会发现我的WinSCP .NET 程序集很有用。
With WinSCP, you can use a code like this to upload all .csv files:
使用 WinSCP，您可以使用这样的代码上传所有 .csv 文件：
Dim sessionOptions As New SessionOptions
With sessionOptions
.Protocol = Protocol.Sftp
.HostName = "example.com"
.UserName = "username"
.UserName = "password"
.SshHostKeyFingerprint = "ssh-rsa 2048 ..."
End With
Using session As New Session
session.Open(sessionOptions)
session.PutFiles("C:\local\path\*.csv", "/remote/path/*").Check()
End Using
WinSCP GUI can generate an upload code template, like the one above, for you.
WinSCP GUI 可以为您生成一个上传代码模板，就像上面的那个一样。
Though, WinSCP .NET assembly is not a native .NET library, it's just a .NET wrapper around a console application. So it has its own limitations.
不过，WinSCP .NET 程序集不是本机 .NET 库，它只是控制台应用程序的 .NET 包装器。所以它有自己的局限性。
