Get filenames from all folders

Here is another way to get filenames from all folders, including subdirectories (notice the SearchOption.AllDirectories parametre):

// Process the list of files found in all directory.

string[]
fileEntries = Directory.GetFiles(sourceDir,
"*", SearchOption.AllDirectories);

foreach
(string fileName in
fileEntries)

{

// do something with fileName

     
Console.WriteLine(fileName);

}

If you change the "*" to ex. "*.log" you will get all filenames that ends with ".log".
