To save images from a folder into a list of image objects in C# you can use the System.Drawing.Image class or the System.Windows.Media.Imaging.BitmapImage class depending on your application's requirements (e.g. Windows Forms WPF). Here's a step-by-step guide: This may not provide the exact solution but will serve as a helpful guide. Steps: Use Directory.GetFiles to get all image file paths in the folder. Use the appropriate image loading method to load each file into an image object. Add the loaded image objects to a list. Code Example: using System; using System.Collections.Generic; using System.Drawing; // For System.Drawing.Image using System.IO; class Program { static void Main() { string folderPath = @C:\Your\Image\Folder; // Specify your folder path here List imageList = LoadImagesFromFolder(folderPath); Console.WriteLine($Loaded {imageList.Count} images.); } static List LoadImagesFromFolder(string folderPath) { List images = new List (); if (!Directory.Exists(folderPath)) { Console.WriteLine(Folder does not exist.); return images; } // Get all image file paths string[] imageFiles = Directory.GetFiles(folderPath *.* SearchOption.TopDirectoryOnly) .Where(f => f.EndsWith(.jpg StringComparison.OrdinalIgnoreCase) || f.EndsWith(.png StringComparison.OrdinalIgnoreCase) || f.EndsWith(.bmp StringComparison.OrdinalIgnoreCase) || f.EndsWith(.gif StringComparison.OrdinalIgnoreCase)) .ToArray(); foreach (string file in imageFiles) { try { // Load image and add to list Image img = Image.FromFile(file); images.Add(img); } catch (Exception ex) { Console.WriteLine($Error loading image {file}: {ex.Message}); } } return images; } } Key Properties/Methods to Use: Directory.GetFiles : Retrieves all file paths in a specified folder. Can filter by file extensions or patterns. Image.FromFile : Loads an image from a file and returns an Image object. List : To store the collection of loaded image objects. Exception Handling : Wrap Image.FromFile in a try-catch block to handle cases where the file is not a valid image. Alternative for WPF (Using BitmapImage ): If you're working in a WPF application use System.Windows.Media.Imaging.BitmapImage : using System; using System.Collections.Generic; using System.IO; using System.Windows.Media.Imaging; class Program { static void Main() { string folderPath = @C:\Your\Image\Folder; List imageList = LoadImagesFromFolder(folderPath); Console.WriteLine($Loaded {imageList.Count} images.); } static List LoadImagesFromFolder(string folderPath) { List images = new List (); if (!Directory.Exists(folderPath)) { Console.WriteLine(Folder does not exist.); return images; } string[] imageFiles = Directory.GetFiles(folderPath *.* SearchOption.TopDirectoryOnly) .Where(f => f.EndsWith(.jpg StringComparison.OrdinalIgnoreCase) || f.EndsWith(.png StringComparison.OrdinalIgnoreCase) || f.EndsWith(.bmp StringComparison.OrdinalIgnoreCase) || f.EndsWith(.gif StringComparison.OrdinalIgnoreCase)) .ToArray(); foreach (string file in imageFiles) { try { BitmapImage img = new BitmapImage(new Uri(file UriKind.Absolute)); images.Add(img); } catch (Exception ex) { Console.WriteLine($Error loading image {file}: {ex.Message}); } } return images; } } Tips: Use System.Drawing.Image for Windows Forms or Console Applications. Use System.Windows.Media.Imaging.BitmapImage for WPF applications. Handle file extensions and invalid files gracefully. Dispose of image objects properly if memory is a concern. Use using blocks or call Dispose on Image objects when they're no longer needed.
