Getting the real COM class name

JensHaffner

This problem really puzzles me...
I???d like to get the ArcObjects CoClass name behind the interface pointer, which I have.
If I???ve got an IFeature pointer, I???d like to know whether it???s in fact a Feature object or perhaps a ComplexEdgeFeature or something else.
No matter what I try, I don???t get the right name???

its a little tricky to get the type of com object. you may have to iterate through all the types and compare the object pointer with array of pointers returned by the com object. Below is the code to accomplish this. Hope this helps

 IntPtr iunkwn = Marshal.GetIUnknownForObject(pWorkspace);
            // enum all the types defined in the interop assembly
            System.Reflection.Assembly objAssembly =
            System.Reflection.Assembly.GetAssembly(typeof(IWorkspace));
            Type[] objTypes = objAssembly.GetTypes();
            // find the first implemented interop type
            foreach (Type currType in objTypes)
            {
                // get the iid of the current type
                Guid iid = currType.GUID;
                if (!currType.IsInterface || iid == Guid.Empty)
                {
                    // com interop type must be an interface with valid iid
                    continue;
                }
                // query supportability of current interface on object
                IntPtr ipointer = IntPtr.Zero;
                Marshal.QueryInterface(iunkwn, ref iid, out ipointer);
                if (ipointer != IntPtr.Zero)
                {
                    string str =currType.FullName;
                }
            }
