Convert method syntax to query syntax

Question

Is there any way to automatically convert from linq method syntax to query syntax?

E.G.: I want to automatically convert it:

var aux = Directory.EnumerateDirectories(@"c:\")
                .Where(directory => directory.Contains("xxx"))
                .ToList();

to it:

var aux = (from directory in Directory.EnumerateDirectories(@"c:\")
                  where directory.Contains("xxx")
                  select directory).ToList();
