Answer 1

Your class is called Image, which is in collision with system defined Image you want to use. So when you try to use Image.FromFile, compiler uses that one defined in your namespace (in your own class) and there's no FromFile method defined.

So when you want to use correct Image class:

1) you should qualify the namespace like: System.Drawing.Image.FromFile

or

2) you can rename your own class to something different from Image, so you have no collision in name
