Call method with assembly loaded from GAC

Question

I am trying to call the Save method from a System.Drawing.Image object, after loading the assembly from the GAC:

_drawingAssembly = Assembly.Load
                    ("System.Drawing, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a");

_drawingAssembly.GetType("Image").GetMethod("Save").Invoke(myImageObject, new object[] { path });

But it's not working. I can't even get the type for some reason; this returns null:

var t = _drawingAssembly.GetType("Image"); // null

You need to have fully qualified name of class while calling `GetType` might be `_drawingAssembly.GetType("System.Drawing.Image")` — Jenish Rabadiya, Apr 01 '15 at 13:16

You need to specify the full type name System.Drawing.Image as indicated by the documentation:

He'll also need to specify which overload of `Image.Save` he wants from `GetMethod`: https://msdn.microsoft.com/en-us/library/6hy0h0z1(v=vs.110).aspx – 15ee8f99-57ff-4f92-890c-b56153 Apr 01 '15 at 13:18
