(C# UWP/WinRT) SFTP Synchronize Directory Tree - DownloadDemonstrates how to download files to synchronize a local directory tree with a remote directory tree. The SyncTreeDownload method recursively descends the remote directory tree and downloads files based on existence, last-mod date/time and/or size differences.
// This example requires the Chilkat SFTP API to have been previously unlocked. // See Unlock Chilkat SFTP for sample code. Chilkat.SFtp sftp = new Chilkat.SFtp(); bool success = await sftp.ConnectAsync("my-ssh-server.com",22); if (success == true) { success = await sftp.AuthenticatePwAsync("mySshLogin","mySshPassword"); } if (success == true) { success = await sftp.InitializeSftpAsync(); } if (success != true) { Debug.WriteLine(sftp.LastErrorText); return; } // Synchronize the remote directory tree rooted at "syncDownloadTest/xml" // with the local directory tree rooted at "qa_output" // Both directories are relative paths. The remote directory // is relative to the HOME directory of the SSH user account. // The local directory is relative to the current working directory of the process. // It is also possible to use absolute paths. string remoteDir = "syncDownloadTest/xml"; string localDir = "qa_output"; // Possible modes that can be passed to the SyncTreeDownload method are: // mode=0: Download all files // mode=1: Download all files that do not exist on the local filesystem. // mode=2: Download newer or non-existant files. // mode=3: Download only newer files. If a file does not already exist on the local filesystem, it is not downloaded from the server. // mode=5: Download only missing files or files with size differences. // mode=6: Same as mode 5, but also download newer files. // mode=99: Do not download files, but instead delete remote files that do not exist locally. // This example will use mode 6 to download missing, newer, or files with size differences. int mode = 6; // This example will turn on recursion to synchronize the entire tree. // Recursion can be turned off to synchronize the files of a single directory. bool recursive = true; success = await sftp.SyncTreeDownloadAsync(remoteDir,localDir,mode,recursive); if (success != true) { Debug.WriteLine(sftp.LastErrorText); return; } Debug.WriteLine("Success."); |
