Invalid type: Schema.SObject

My requirement is, whenever the checkbox is checked on Contact Object then records in the related junction object(Custom Object) should gets deleted automatically.
For that here is the code:

public class DeleteContactsFromRSites {

    @InvocableMethod
    public static void SiteContactDel(List<Id> ContactIds) {

        System.debug('list of contacts ' + ContactIds);

        List<Site_Contact__c> resultList = [SELECT Id, Contact__r.name, 
                                                    , Contact__r.id
                                                    , Contact_r.In_Active__c 
                                             FROM Site_Contact_c 
                                             Where Contact__r.id IN :ContactIds 
                                                And Contact_r.In_Active__c = true];
        System.debug('the list of record to delete' + resultList);

        try{
            if (!resultList.isEmpty()) {
                delete resultList;

                for(Integer i=0;i<resultList.size();i++)
                    System.debug('deleted list of contacts ' + resultList[i].id + '  name is ' + resultList[i].Contact__r.Name);
            }
        }
        catch(Exception e){
            System.debug('Deletion of records failed:' + e);
        }
    }
}

Please Let me know where exactly the error is.
