title: Cannot delete an image file that is shown in a listview
body: <p>In my listview I show thumbnails of small images in a certain folder. I setup the listview as follows:</p>
  
  <pre><code>var imageList = new ImageList();
  foreach (var fileInfo in dir.GetFiles())
  {
      try
      {
          var image = Image.FromFile(fileInfo.FullName);
          imageList.Images.Add(image);
      }
      catch
      {
          Console.WriteLine("error");
      }
  }
  
  listView.View = View.LargeIcon;
  imageList.ImageSize = new Size(64, 64);
  listView.LargeImageList = imageList;
  
  for (int j = 0; j &lt; imageList.Images.Count; j++)
  {
      var item = new ListViewItem {ImageIndex = j, Text = "blabla"};
      listView.Items.Add(item);
  }
  </code></pre>
  
  <p>The user can rightclick on an image in the listview to remove it. I remove it from the listview and then I want to delete this image from the folder. Now I get the error that the file is in use. Of course this is logical since the imagelist is using the file.</p>
  
  <p>I tried to first remove the image from the imagelist, but I keep on having the file lock.</p>
  
  <p>Can somebody tell me what I am doing wrong?</p>
  
  <p>Thanks!</p>
