FTP downloading files using patterns

Downloading files using patters is a unique feature of our FTP .NET component. It allows you fast download of files of certain types.

Here’s the sample that download all text files (*.txt) files from remote Uploads folder to Downloads folder located on C drive. Remote search includes all child folders recursively – note the true parameter in RemoteSearchOptions constructor. Ftp component is going to create all necessary folders on the local computer.

// C#

using (Ftp ftp = new Ftp())
{
    ftp.Connect("ftp.example.com");    // or ConnectSSL
    Directory.CreateDirectory(@"c:\Downloads");
    ftp.DownloadFiles("Uploads", @"c:\Downloads", new RemoteSearchOptions("*.txt", true));
    ftp.Close();
}

' VB.NET

Using ftp As New Ftp()
	ftp.Connect("ftp.example.com")    ' or ConnectSSL
	Directory.CreateDirectory("c:\Downloads")
	ftp.DownloadFiles("Uploads", "c:\Downloads", New RemoteSearchOptions("*.txt", True))
	ftp.Close()
End Using

You can also set RemoteSearchOptions.UseRegex property to true, if you want to use regex patterns on remote names:

// C#

RemoteSearchOptionsoptions = new RemoteSearchOptions(@"^.*\.txt$", true);
options.FolderPattern = @"^.*$";
options.UseRegex = true;

ftp.DownloadFiles("Uploads", @"c:\Downloads", options);

' VB.NET

Dim options As New RemoteSearchOptions("^.*\.txt$", True)
options.FolderPattern = "^.*$"
options.UseRegex = True

ftp.DownloadFiles("Uploads", "c:\Downloads", options)
