System.Collections.Generic.IEnumerable<RemoteFileInfo> MatchedFiles = session.EnumerateRemoteFiles(SFTPRootDir, FileNamePattern, EnumerationOptions.None);
FileNamePatternis the fileMask pattern one can pass and transfer file to local path.

FileNamePattern filter will be like
How can get the solution.
