Counting files with a given extension??

I am needing to count the files inside a certain directory with a certain filemask (eg: "*.ini")when a given event occurs.  I do not need a recursive search through sub directories

I know I can load each into an array and count them there.  I am wondering if there is a directory* or file* class in c++ .net that would be quicker to execute and code??

Thanks, Jason
