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.

Download using wildcard pattern

// C#

using (Ftp ftp = new Ftp())
{
    ftp.Connect("ftp.example.com");    // or ConnectSSL
    
    Directory.CreateDirectory(@"c:\Downloads");

    RemoteSearchOptions options = new RemoteSearchOptions("*.txt", true);
    ftp.DownloadFiles("Uploads", @"c:\Downloads", options);

    ftp.Close();
}

' VB.NET

Using ftp As New Ftp()
    ftp.Connect("ftp.example.com")    ' or ConnectSSL

    Directory.CreateDirectory("c:\Downloads")
    
    Dim options As RemoteSearchOptions = _
        New RemoteSearchOptions("*.txt", True)
    ftp.DownloadFiles("Uploads", "c:\Downloads", options)

    ftp.Close()
End Using

Download using regex pattern

You can also use RemoteSearchOptions.UseRegexMatch method, if you want to use regex patterns on remote names:

// C#

using (Ftp ftp = new Ftp())
{
    ftp.Connect("ftp.example.com");    // or ConnectSSL
    
    Directory.CreateDirectory(@"c:\Downloads");

    RemoteSearchOptions options = new RemoteSearchOptions();
    options.UseRegexMatch(@"^.*$", @"^.*\.txt$", true);
    ftp.DownloadFiles("Uploads", @"c:\Downloads", options);

    ftp.Close();
}

' VB.NET

Using ftp As New Ftp()
    ftp.Connect("ftp.example.com")	' or ConnectSSL

    Directory.CreateDirectory("c:\Downloads")

    Dim options As RemoteSearchOptions = _
        New RemoteSearchOptions()
    options.UseRegexMatch("^.*$", "^.*\.txt$", True)
    ftp.DownloadFiles("Uploads", "c:\Downloads", options)

    ftp.Close()
End Using
