ObjectCopier to Copy Common Properties between objects

A useful method to copy properties from one object to another object which has common properties. This is useful is you have a design which uses DTO type objects. Rather than going and writing lines of copy type code you can make a single call to

ObjectCopier.CopyCommonProperties(object1, object2);

        public static void CopyCommonProperties(object source, object destination)
        {
            var myObjectFields = destination.GetType().GetProperties(BindingFlags.Public | BindingFlags.Instance);
            foreach (var pi in myObjectFields)
            {
                if (pi.CanWrite)
                {
                    var sourcepi = source.GetType().GetProperty(pi.Name);
                    if (sourcepi != null && sourcepi.CanRead)
                        if (pi.PropertyType.FullName == sourcepi.PropertyType.FullName)
                            pi.SetValue(destination, sourcepi.GetValue(source, null), null);
                }
            }
        }

            object1.Attribute3 = DateTime.Now;

            // ObjectCopier dones the same as the following
            //TestClass object2 = new TestClass();
