I think my code is simple:
string token = "sl.<REDACTED>";
var dbx = new DropboxClient(token);
var res = await dbx.Files.ListFolderAsync(path: "");
foreach (var entry in res.Entries)
{
Console.WriteLine(entry.Name);
}
if have no entries (Count=0) here.
I have 4 folders and 1 file in in my dropbox folder.
