To set the ‘default’ image for a button from local images, call SetImage 

button1 = UIButton.FromType(UIButtonType.RoundedRect);
button1.SetImage(UIImage.FromFile ("sample.png"), UIControlState.Normal);

To apply from an URL,

button1  = FindViewById(Resource.Id.RoundedRect);
var imageBitmap = GetImageBitmapFromUrl("http://xamarin.com/resources/design/home/test.png");
button1.SetImageBitmap(imageBitmap);


private Bitmap GetImageBitmapFromUrl(string url)
{
     Bitmap imageBitmap = null;

     using (var webClient = new WebClient())
     {
          var imageBytes = webClient.DownloadData(url);
          if (imageBytes != null && imageBytes.Length > 0)
          {
               imageBitmap = BitmapFactory.DecodeByteArray(imageBytes, 0, imageBytes.Length);
          }
     }

     return imageBitmap;
}
