Loading Thumbnails in Code-Behind

The code below demonstrates how to show an open file dialog and set the ItemsSource to a collection containing a filename string for each selected file:

C# Example	Copy Code
OpenFileDialog ofd = new OpenFileDialog(); ofd.Multiselect = true; ofd.ShowDialog(); ObservableCollection<string> thumbnailFiles = new ObservableCollection<string>(); foreach (string fileInfo in ofd.FileNames) { thumbnailFiles.Add(fileInfo); } thumbnailList.ItemsSource = thumbnailFiles;

C# Example

Copy Code

        OpenFileDialog ofd = new OpenFileDialog();
        ofd.Multiselect = true;
        ofd.ShowDialog();
            
        ObservableCollection<string> thumbnailFiles = new ObservableCollection<string>();
        foreach (string fileInfo in ofd.FileNames)
        {
            thumbnailFiles.Add(fileInfo);
        }
        thumbnailList.ItemsSource = thumbnailFiles;
