Is there anyway to change images in a imagebox of emgucv using folderbrowser dialog box. I also need to select images from subfolders I tried this:

C#

private void btSelectFolder_Click(object sender, EventArgs e)
{
        FolderBrowserDialog ofd = new FolderBrowserDialog();
        if (ofd.ShowDialog(this) == System.Windows.Forms.DialogResult.OK)
            try
            {
                textBox7.Text = ofd.SelectedPath;
                image = Directory.GetFiles(ofd.SelectedPath, "*.jpg");
//trying to get all image files
                frame = new Image<Bgr, byte>((Bitmap)Bitmap.image);
// I get error here//this line is to convert image to emguCV image type
            }
            catch (Exception ex)
            {
                MessageBox.Show(ex.Message);

I'm trying to process images from sub-folders which are in a folder and display in image box as it processes.. Im doing contour analysis.. I need to process every image in all sub-folders one by one.. the images are in .jpg format and I tried converting them to a format that a emgucv image box accepts.. But i get errors there.. My problems are two: 1. I dont know how to load images from the folders.. 2.I dont know to convert the image.. Sorry If my question was poor.. Im a beginner here and also for c# emgucv.. Ill be thankful.. If i got a help.. Hope u understand what I need to do?

Hi,

Problem 1 :I don't know how to load images from the folders

C#

FolderBrowserDialog fbd = new FolderBrowserDialog();
            DialogResult result = fbd.ShowDialog();
            string[] files = { };
            if (result == System.Windows.Forms.DialogResult.OK)
                files = Directory.GetFiles(fbd.SelectedPath, "*.jpg", SearchOption.AllDirectories);

Problem 2 : I dont know to convert the image

C#

foreach (var file in files)
           {
               Image<bgr, byte> EmguImage = new Image<bgr, byte>(new Bitmap(file));
           }
