Here shows you how to use regex in C#.
You could always just loop the directory that you’re looking in and check the file names instead of making a regex. (You’ll need to use System.IO)
Perhaps something like this?
string [] fileEntries = Directory.GetFiles(targetDirectory);
Regex regex = new Regex("target file name");
Match match = regex.Match(string.Join(" ", fileEntries););
if (match.Success)
{
Console.WriteLine(match.Value);
}
