OpenFileDialog - display only file names that do not have extensions

Question

I have the following code in my C # program:

        OpenFileDialog fDialog = new OpenFileDialog();
        fDialog.Title = "Open a file";
        fDialog.Filter =
           "NCF files (*.ncf)|*.ncf|All files (*.*)|*.*|No Extensions (*.)|*.";

I want the user to be able to choose from the following:

*. NCF (only files with the extension .NCF)
**. * (all files)

and files with no extensions , such as:

<w> filewithnoextension



I know ***. * Will do this, but also displays .NCF, .TXT and all other files in the same directory.

I just want to display the names of files that do not have extensions.



Filtering with *. doesn't do the trick. It works great when it does this with a DOS window ( dir *. ), But C # seems to ignore *. filter.

Is there a way to do this using C #?

Thank.
