How can I make my class not be NULL?

This is the constructor that we have been referring to:

       public  C1()
        {
            InitializeComponent();

            // Clear out placeholder content
            this.wrapPanel.Children.Clear();

            // Add in display content
            //for (var index = 0; index < 300; ++index)
            //{
            //    var button = new KinectTileButton { Label = (index + 1).ToString(CultureInfo.CurrentCulture) };
            //    this.wrapPanel.Children.Add(button);
            //}

            try
            {
                var files = Directory.GetFiles(@".\GalleryImages");
                string[] names = new string[13] { "Cosmin Contra l-a introdus din primul minut pe Ciprian Marica, în timp ce Diego Simeone l-a din nou la dispoziţie pe Diego Costa. Atacantul a ratat un penalty, apoi a dus scorul la 2-0, moment în care s-a şi accidentat, lovind cu genunchiul în bara porţii.", "Joanne", "Robert", "Andrei", "Mihai", "Radu", "Ionica", "Vasile","Cristi","Bogdan","Marian","Georgel","Dan" };

                int i = 0;
                foreach (var file in files)
                {
                    
                  
   
                        FileInfo fileInfo = new FileInfo(file);

                        WineModel wineModel = new WineModel();
                        wineModel.Image = new Uri(file, UriKind.Relative);
                        wineModel.Description = names[i++];
                        wineModel.Price = new Random().NextDouble();

                        BitmapImage bi = new BitmapImage();
                        bi.BeginInit();
                        bi.UriSource = wineModel.Image;

                        bi.EndInit();

                        var button = new KinectTileButton
                        {
                            Label = System.IO.Path.GetFileNameWithoutExtension(file),

                            Background = new ImageBrush(bi),
                            Tag = wineModel
                        };

                        this.wrapPanel.Children.Add(button);
                    
                }
            }

            catch (Exception ex)
            {
                //TODO: Add logging
            }

            // Bind listner to scrollviwer scroll position change, and check scroll viewer position
            this.UpdatePagingButtonState();
            scrollViewer.ScrollChanged += (o, e) => this.UpdatePagingButtonState();
        }

which is what is called when this line executes:

C1 C1 = new C1();
