Duplicate in List

In my order insert trigger, i need to update contact for the order information, I know there are duplicate records in the my contact list. so I use

Contact[] contactToUpdate = new List<Contact>(new Set<Contact>(contactList));

to remove the duplicates. 

 

but I still receive the error message: duplicate in List. 

 

any idea?? 

 

Thanks

List datatype always contain duplicate value. Please use set datatype to remove duplicate.
