     if (result == true)
     {
       //imagebox.Source = openfile.FileName;
     }

Answer 1

you'll need to change the File Name into a URI and then create a bitmapimage

:

if (File.Exists(openfile.FileName))
{
 // Create image element to set as icon on the menu element
 BitmapImage bmImage = new BitmapImage();
 bmImage.BeginInit();
 bmImage.UriSource = new Uri(openfile.FileName, UriKind.Absolute);
 bmImage.EndInit();
 // imagebox.Source = bmImage;
}

Answer 2

imagebox.Source = new BitmapImage(new Uri(openfile.FileName));

Answer 3

You can also add the image as a resource, ie Add Existing item and change the image's Build Action property to Resource

then reference it this way

BitmapImage bitImg = new BitmapImage(); bitImg.BeginInit(); bitImg.UriSource = new Uri("./Resource/Images/Bar1.png", UriKind.Relative); bitImg.EndInit();

        ((Image)sender).Source = bitImg;

This way you dont need to include the image with the program, its bundled into the package as a resource
