How to share data with background worker c#

Question

Hello I´m using a backgroundworker to load tumbnail images on to a listView which is on a form.

but i cant access the listview component from the backgroundworker.

         private void backgroundWorker1_DoWork(object sender, DoWorkEventArgs e)
        {
            FileSearch searcher = new FileSearch();
            searcher.SearchExtensions.AddRange(new string[] { ".jpg", ".bmp", ".png" });
            searcher.Recursive = false; // do not include subfolders!

            FileInfo[] files = searcher.Search(folderPath);

            ImageList ilist = new ImageList();
            listView1.LargeImageList = ilist;

            //listView appearance settings
            ilist.ImageSize = new Size(128, 64);
            ilist.ColorDepth = ColorDepth.Depth24Bit;
            ListView_SetSpacing(listView1, 128 + 2, 64 + 30);

            for (int i = 0; i < files.GetLength(0); i++)
            {
                Image img = Image.FromFile(files[i].FullName);
                ilist.Images.Add(img.GetThumbnailImage(128, 64, null, new System.IntPtr()));
                img.Dispose();
                ListViewItem lvi = new ListViewItem(files[i].Name);
                lvi.ImageIndex = i;
                listView1.Items.Add(lvi);
                backgroundWorker1.ReportProgress((i*100)/files.Length);
            }
        }

so listView1 (as all the other components on my form)  can't be accesed from 'private void backgroundWorker1_DoWork(object sender, DoWorkEventArgs e)'

What would be the correct way to handle this?

Thanks in advance :)
