   System.Xml.Linq.XName name
)

container: The element or document containing the element.

Remarks

Hints are used declaratively. They tell LiveLinq query optimizer to create and use an index on this element, if possible. When the query is executed, the hint method IndexedElement is replaced with the standard LINQ to XML method System.Xml.Linq.XContainer.Element(System.Xml.Linq.XName). See C1.LiveLinq.Hints for more details.

Example

var query =
    from c in customers
    where (string)c.IndexedElement("CustomerID") == "ALFKI"
    select c;
