// This example assumes the Chilkat API to have been previously unlocked.
// See Global Unlock Sample for sample code.

Chilkat.SFtp sftp = new Chilkat.SFtp();

// Set some timeouts, in milliseconds:
sftp.ConnectTimeoutMs = 15000;
sftp.IdleTimeoutMs = 15000;

// Connect to the SSH server.  
// The standard SSH port = 22
// The hostname may be a hostname or IP address.
string hostname = "sftp.example.com";
int port = 22;
bool success = await sftp.ConnectAsync(hostname,port);
if (success != true) {
    Debug.WriteLine(sftp.LastErrorText);
    return;
}

// Authenticate with the SSH server.  Chilkat SFTP supports
// both password-based authenication as well as public-key
// authentication.  This example uses password authenication.
success = await sftp.AuthenticatePwAsync("myLogin","myPassword");
if (success != true) {
    Debug.WriteLine(sftp.LastErrorText);
    return;
}

// After authenticating, the SFTP subsystem must be initialized:
success = await sftp.InitializeSftpAsync();
if (success != true) {
    Debug.WriteLine(sftp.LastErrorText);
    return;
}

// Download the file:
string remoteFilePath;
string localFilePath;
localFilePath = "c:/temp/hamlet.xml";
// Note: The remote filepath may be an absolute filepath,
// a relative filepath, or simply a filename.  
// Relative filepaths are always relative to the home directory
// of the SFTP/SSH user account.  There is no such thing
// as "current remote directory" in the SFTP protocol. 
// A filename with no path implies that the file is located
// in the SFTP user account's home directory.
remoteFilePath = "subdir1/subdir2/hamlet.xml";
success = await sftp.DownloadFileByNameAsync(remoteFilePath,localFilePath);
if (success != true) {
    Debug.WriteLine(sftp.LastErrorText);
    return;
}

Debug.WriteLine("Success.");
