  The following example demonstrates the find methods for the <xref:System.Collections.Generic.List%601> class. The example for the <xref:System.Collections.Generic.List%601> class contains `book` objects, of class `Book`, using the data from the [Sample XML File: Books (LINQ to XML)](https://msdn.microsoft.com/library/94252daf-6097-4625-afc2-0eb778958d4f). The `FillList` method in the example uses [LINQ to XML](https://msdn.microsoft.com/library/f0fe21e9-ee43-4a55-b91a-0800e5782c13) to parse the values from the XML to property values of the `book` objects.
