ObjectQuery<T> without Entity Framework
How to use ObjectContext
and ObjectQuery<T>
with my own c开发者_如何学Pythonlasses and objects?
I.e. I don't want to use them with Entity Framework.
How can I do this?
ObjectContext and ObjectQuery are the Entity Framework. You could implement your own Custom Linq Provider. A very good example can be found at "THE WAYWARD WEBLOG" http://blogs.msdn.com/mattwar/pages/linq-links.aspx. This Blog helped me implementing my own custom Provider.
public interface IQueryable : IEnumerable {
Type ElementType { get; }
Expression Expression { get; }
IQueryProvider Provider { get; }
}
public interface IQueryProvider {
IQueryable CreateQuery(Expression expression);
IQueryable<TElement> CreateQuery<TElement>(Expression expression);
object Execute(Expression expression);
TResult Execute<TResult>(Expression expression);
}
