System. IO. Directory. GetFiles (" c: \ ", "(*. Exe | *. TXT)");

Oh, still can't believe I was wrong, baidu

The need to use linq,
Can be a var files=dinfo. GetFiles (" *.jpg ")
Concat (dinfo. GetFiles (" *. Tiff "))
Concat (dinfo. GetFiles (" *. BMP "));
This

Can also be getfiles (). The where

Yes, look at the Microsoft data searchPattern merger does not support multiple parameters, so only found out after array to merge, respectively

As for you to use linq or usually add or addrage operating this see you an array of familiarity, can not see the array operation document:
