Context: my end user selects an image from his computer to use as his Profile pic in my C# standalone desktop application. And the backend basically copies the image selected by the end user in the app’s local folder created in User/Documents (also handled in backend).

I want to create a functionality to delete the previous image which was copied to the app’s local folder in the User/Documents and not fill the folder up by keep copying new images.

The RegisterPage.xaml.cs (selection and copying the image)

private void OpenImageFileButton_Click(object sender, RoutedEventArgs e)
{
    OpenFileDialog openFileDialog = new OpenFileDialog();
    openFileDialog.Filter = "Image files (*.png;)|*.png;";
    openFileDialog.InitialDirectory = @"C:"; // Set the initial directory (optional)
    
    if (openFileDialog.ShowDialog() == true)
    {
        string destinationFilePath;
        // Get the selected file path
        string selectedImagePath = openFileDialog.FileName;
        try
        {
            string documentsPath = Environment.GetFolderPath(Environment.SpecialFolder.MyDocuments);

            // Create the directory if it doesn't exist
            string directoryPath = System.IO.Path.Combine(documentsPath, "FT_SGS", "myschoolinfo");
            Directory.CreateDirectory(directoryPath);
            
            // Get the file name from the selected image path
            string fileName = System.IO.Path.GetFileName(selectedImagePath);

            // Combine the destination folder path with the file name
            destinationFilePath = System.IO.Path.Combine(directoryPath, fileName);

            // Copy the image file
            File.Copy(selectedImagePath, destinationFilePath, true);
            BitmapImage bitmapImage = new BitmapImage();
            bitmapImage.BeginInit();
            bitmapImage.UriSource = new Uri(destinationFilePath, UriKind.RelativeOrAbsolute);
            bitmapImage.EndInit();
            this.schllogo.Source = bitmapImage;
            // Now you can use 'selectedImagePath' as needed (e.g., load it into an Image control)

        }
        catch (Exception ex)
        {
            MessageBox.Show($"Error processing image:n{ex.Message}", "Error", MessageBoxButton.OK, MessageBoxImage.Error);
        }                
    }
}
