Answer 1

I understand that you want to order the items by the extension, this can be done in this way:

        List<string> fileNames = new List<string>();
        fileNames.Add("Form.frm");
        fileNames.Add("Form1.frm");
        fileNames.Add("Form2.frm");
        fileNames.Add("Module.bas");
        fileNames.Add("Module23.bas");

        var ordered = fileNames.OrderBy(p => Path.GetExtension(p));
