How can I add different validation of a document extension, if I´m using GetFiles?

[ppr (Peter Preuss)]

e.g.

arrFullFilePaths | String() - String Array =

(From f in Directory.GetFiles(MyDirPathVar)
Let xt = Path.GetExtension(f).toUpper.Replace(".","")
Where {"PDF","TXT","XML"}.Contains(xt)
Select fp = f).toArray
