#Win32 api gettimestamp as file time serial
In C#, we can use the foreach expression to enumerate some kind of serial value. Using these 3 Win32 APIs, we can enumerate file and sub directory, efficiently and in a controllable manner. Obviously the System.IO.DirectoryInfo.GetDirectories/ GetFiles is inefficient and a waste of time. Sometimes we just want to know if there are some special kind of file or sub directories in a directory. We can use System.IO.DirectoryInfo.GetDirectories or GetFiles to get all file and sub directories.
