Answer 1

Use the following:

• img.PropertyIdList.Contains(orientationId) to check if the Exif tag is present.
• img.GetPropertyItem(orientationId) to get it (after the above check, otherwise you'll get an ArgumentException).
• img.SetPropertyItem(pItem) to set it.

I wrote a simple helper class that does all that: you can check the full source code here.
