DirectoryInfo's GetFileInfo Search pattern question

[Mullin Yu]

e.g. c:\test

doc1.txt
doc1.pdf
doc2.txt
doc2.pdf
doc3.txt
doc4.pdf
doc5.txt
doc5.pdf

only doc1, doc and doc5 will be returned as has both .txt and .pdf files

how to implement? i'm not sure whether the DirectoryInfo's GetFileInfo's
seach pattern can do so or not?

You'll have to call the method multiple times, each time with one of the
file patterns. Make sure that the result of the patterns is distinct so you
don't get the same file more than one time.
