Delete directory with WinSCP .NET assembly

Have to questions cause can't find it:

1. How to check if directory contains anything e.g folder or files, whatever... or is it empty

2. How to remove an empty directory?

3. How to remove a directory even if there is content.

For instance for creating directory I am using below function:

Public Sub CreateDirectory(path As String)
    If session IsNot Nothing Then
        session.CreateDirectory(path)
    End If
End Sub

To check, if there are any files in a directory, use the Session.EnumerateRemoteFiles method:

Dim anyFile As Boolean =
    mySession.EnumerateRemoteFiles(
        path, Nothing, EnumerationOptions.MatchDirectories).Any()

The Session.EnumerateRemoteFiles is supported since WinSCP 5.9.

With older versions of WinSCP, list directory contents using the Session.ListDirectory and filter out the this (.) and parent (..) entries:

Dim anyFile As Boolean =
    mySession.ListDirectory(path).Files.
    Where(Function(file) Not file.IsThisDirectory And Not file.IsParentDirectory).
    Any()

To remove any directory, be it empty or not, use Session.RemoveFiles:

session.RemoveFiles(RemotePath.EscapeFileMask(path))
