Filesystemwatcher doesn't trigger event

Question

I am trying to monitor a directory for new files in it with the FileSystemWatcher Class.

My Problem is that the event doesn't get triggered. My watcher class is:

public class Filewatcher
{
    private FileSystemWatcher watcher;

    public Filewatcher(string path, string filefilter)
    {
        this.watcher = new FileSystemWatcher();
        this.watcher.Path = path;
        this.watcher.NotifyFilter = NotifyFilters.FileName; //| NotifyFilters.LastWrite | NotifyFilters.LastAccess
        this.watcher.Filter =  filefilter;
        this.watcher.Created += new FileSystemEventHandler(OnChanged);
    }

    public void start_watching()
    {
        //this.watcher.IncludeSubdirectories = true;
        this.watcher.EnableRaisingEvents = true;

        Console.WriteLine("Press Enter to quit\r\n");
        Console.ReadLine(); 
    }

    private static void OnChanged(object source, FileSystemEventArgs e)
    {
        //FileInfo objFileInfo = new FileInfo(e.FullPath);
        //if (!objFileInfo.Exists) return;
        Console.WriteLine("got the change\r\n");
        global_functions.perform_action(Global_Vars.thereader.read(e.FullPath), Global_Vars.thepattern);
    }
}

Operating System is Win 7 Prof x64

what is the content of filefilter variable!Are you filtering for specific files..try *.* to enable raising events for any type of file — Anirudha

We'll need a complete but simple example that reproduces the problem. If I take your code and instantiate a Filewatcher object with new Filewatcher(".", "*.*") and call start_watcher on that instance then create file in the same directory as the exe, OnChanged is called — Peter Ritchie

You don't make a call to start_watching(). Add a call to that and it may work better.
