This code sample demonstrates how to implement an IEnumerable<string> that utilizes the Win32 File Management functions to enable application to get files and sub-directories in a specified directory.

The FileEnumerator class in this sample project solves a common problem in the System.IO.Directory.GetFiles method - if a directory contains a largenumber of items, this it will take a long time for this method to returnbecause it will enumerate all the files and put the names in an array asan entire operation. This will also cause a very high memory load if the array gets huge.

The FileEnumerator class works differently. It returns one file at a time.And the enumeration can be canceled or reset at anytime.
