SubSonic - Using the Exist() Method using predicates

Here is a simple example on how to use the Exist() method that hangs of the collection entities generated by SubSonic.

for (int i = 0; i < originalentitycollection.Count; i++)
{
   Predicate exist = delegate(Model.Person match)
   {
      if (match.PersonId == originalentitycollection[i].PersonId)
         return true;
      else return false;
    };


   if (!distinctpersoncollection.exists(exist))
   {
                              
      distinctpersoncollection.add(originalentitycollection[i]);
   }
}
