List files with specific extension using WinSCP .NET assembly

Question

I am using WinSCP .NET assembly to do a download and upload through SFTP with C# .NET. I have the download function working but I am looking for a way to have the files in the remote server listed (or at least listed with a specific extension) so user only have to choose from those files with the specific extension (like .txt) to get the files they want.

Is there a way to do that with WinSCP .NET assembly?

Answer 1

Use the Session.ListDirectories method:

RemoteDirectoryInfo directory = session.ListDirectory("/home/martin");

foreach (RemoteFileInfo fileInfo in directory.Files)
{
    string extension = Path.GetExtension(fileInfo.Name);
    if (string.Compare(extension, ".txt", true) == 0)
    {
        Console.WriteLine("Adding {0} to listing", fileInfo.Name);
    }
}

Or the Session.EnumerateRemoteFiles method:

IEnumerable<RemoteFileInfo> fileInfos =
    session.EnumerateRemoteFiles("/home/martin", "*.txt", EnumerationOptions.None);
foreach (RemoteFileInfo fileInfo in fileInfos)
{
    Console.WriteLine("Adding {0} to listing", fileInfo.Name);
}

Answer 2

Yes, you can use the RemoteFileInfo and RemoteDirectoryInfo classes to get remote file and directory details. Then, depending on your requirements, you can use custom logic to retrieve specific files.
