• Something like this might work:

  [DllImport("ole32.dll")]

  static extern int ProgIDFromCLSID([In] ref Guid clsid, [MarshalAs(UnmanagedType.LPWStr)] out string lplpszProgID);

  . . .

  object tmpComObj = Activator.CreateInstance(comType);

  IPersist persist = comObj as IPersist;

  if (persist != null)

  {

  Guid classId;

  persist.GetClassID(out classId);

  string progId;

  ProgIDFromCLSID(ref classId, out progId);

  Console.WriteLine("Progid = {0}, CLSID = {1}", progId, classId);

  }

  Marshal.ReleaseComObject(tmpComObj);
