I'm attempting to implement a repository pattern with my poco objects auto generated from my edmx.
In my repository class, I have:
IObjectSet<E> _objectSet;
private IObjectSet<E> objectSet
{
get
{
if (_objectSet == null)
{
_objectSet = this._context.CreateObjectSet<E>();
}
return _objectSet;
}
}
public IQueryable<E> GetQuery(Func<E, bool> where)
{
return objectSet.Where(where).AsQueryable<E>();
}
public IList<E> SelectAll(Func<E, bool> where)
{
return GetQuery(where).ToList();
}
Where E is the one of my POCO classes. When I trace the database and run this:
IList<Contact> c = contactRepository.SelectAll(r => r.emailAddress == "
[email protected]");
It shows up in the sql trace as a select for everything in my Contact
table. Where am I going wrong here?
Is there a better way to do this? Does an objectset not lazy load... so it omitted the where clause?
This is the article I read which said to use objectSet's... since with POCO, I do not have EntityObject's to pass into "E"
