Return Value

Type: System.Linq.IQueryable<TElement>
An IQueryable<T> that can evaluate the query represented by the specified expression tree.

NoteNote

The Expression property of the returned IQueryable<T> object is equal to expression.

The CreateQuery method is used to create new IQueryable<T> objects, given an expression tree. The query that is represented by the returned object is associated with a specific LINQ provider.

Most of the Queryable standard query operator methods that return enumerable results call this method. They pass it a MethodCallExpression that represents a LINQ query.
