I am trying to connect to an SFTP but am getting the following error from Chilkat in the function sftp.Connect(hostname, port)...

I am primarily using the 4 functions to connect to SFTP

sftp.UnlockComponent(ChilkatKey);
sftp.Connect(hostname, port);
sftp.AuthenticatePw(username, password);
sftp.InitializeSftp();

What am I missing ? Thanks for your help.

正确的顺序应该和你的一样：

sftp.UnlockComponent(ChilkatKey);
sftp.Connect(hostname, port);
sftp.AuthenticatePw(username, password);
sftp.InitializeSftp();

但是在这些家伙之后，你需要调用 OpenDir 和 ReadDir（如果你需要获取远程文件夹上的文件数）方法，比如；

string handler = sftp.OpenDir("remote_path");
SFtpDir compassDir = sftp.ReadDir(handler);

只需下载不需要调用 ReadDir 但必须调用 OpenDir 的文件。在填充 compassDir 对象之后，您可以获得文件计数；

int fileAmount = compassDir.NumFilesAndDirs

或者您可以按名称下载文件，例如；

sftp.DownloadFileByName("local_path","Remote_path_with_file_name");

很抱歉错字错误。
