Maybe I need a regex?

I am making a simple console application for a home project. Basically, it controls the folder for any added files.

FileSystemWatcher fsw = new FileSystemWatcher(@"c:\temp");
fsw.Created += new FileSystemEventHandler(fsw_Created);

bool monitor = true;

while (monitor)
{
    fsw.WaitForChanged(WatcherChangeTypes.Created, 1000);
    if(Console.KeyAvailable)
    {
        monitor = false;
    }
}

Show("User has quit the process...", ConsoleColor.Yellow);

When new files appear, WaitForChanges is called and I can get started.

What I need to do is check the file name for the templates. In real life, I put video files in this folder. Based on the file name, I will have rules that move files to specific directories. So, for now, I will have a list of KeyValue pairs ... containing RegEx (I think?) And a folder. So, if the file name matches the regular expression, it moves it to the appropriate folder.

Example file name:

CSI- NY.S07E01.The 34th Floor.avi

, Regex , CSI "AND" (NY "OR" NewYork "" New York "). , \Series\CSI\NY\.

, :

CSI- Crime Scene Investigation.S11E16.Turn On, Tune In, Drop Dead

, NOT. , , CSI, NOT ( "-" "-" "-" )
