First you have to write the image:

System.Drawing.Image image = System.Drawing.Image.FromStream (new System.IO.MemoryStream(byteArrayHere));

and afterwards you have the :

image.Height.ToString(); 

and the

image.Width.ToString();

note: you might want to add a check to be sure it's an image that was uploaded?
